Maiden Mineral resource for Faboliden gold deposit

ASX Announcement



ASX ANNOUNCEMENT 31 DECEMBER 2015


MAIDEN MINERAL RESOURCE FOR FÄBOLIDEN GOLD DEPOSIT


  • Fäboliden Mineral Resource totals 743,000 ounces grading 3.3 g/t gold;

  • Detailed open-pit mining study in progress.


Dragon Mining Limited (ASX:DRA) ("Dragon Mining" or "the Company") is pleased to announce the completion of the maiden Mineral Resource estimate for the higher grade zone of gold mineralisation on the Fäboliden Gold Project ("Fäboliden') in northern Sweden. The maiden estimate totals 6,900,000 tonnes grading 3.3 g/t gold for 743,000 ounces and incorporates all results from the Diamond core drilling campaign completed earlier in 2015 that confirmed and better delineated the extent and geometry of the near surface, higher grade zone of gold mineralisation in the southern portion of the Fäboliden Gold Deposit.


The Mineral Resource estimate was prepared by independent consultants RungePincockMinarco Limited in Perth, Western Australia and has been reported in accordance with the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves ("the JORC Code").


The Fäboliden Gold Deposit is a medium grade body of gold mineralisation that has good potential for exploitation by open-pit and underground mining methods. The deposit is now subject to a detailed open-pit mining study as Dragon Mining continues to evaluate the viability of establishing a new gold mine in close proximity to the Company's existing processing infrastructure at Svartliden. A second phase of bench scale metallurgical test work is also in progress, with the results expected to be available during the first quarter in 2016, whilst preparation of applications for a test mining campaign and a new Environmental Permit are advancing.


Executive Director Mr. Brett Smith stated, "The Fäboliden Mineral Resource result is extremely encouraging. It highlights the overall potential of the recently acquired Fäboliden Gold Project and provides a solid foundation from which the project can progress into development in the earliest possible time frame."

Fäboliden is an advanced gold project located 30 kilometres by road, southeast of Dragon Mining's wholly owned Svartliden Production Centre and 750 kilometres north of the Swedish capital Stockholm. It represents a potential source of gold bearing material that could be trucked to, and processed at Svartliden, an operating 300,000 tonne per annum conventional comminution and carbon in leach (CIL) plant.

The 1,739.57 hectare Fäboliden project comprises the Fäboliden K nr 1 Exploitation Concession that hosts the Fäboliden Gold Deposit and four contiguous Exploration Permits that encompass the southwest strike extensions of the deposits host geological sequence.


The Fäboliden Gold Deposit is an orogenic gold deposit, with mineralisation hosted by Paleoproterozoic meta- sediments and meta-volcanic rocks, surrounded by granitoids. The host sequence is cross-cut by a set of northwest-southeast striking, flat lying undeformed and unmineralised dolerites.


The mineralised system is delineated over a strike length of 1,295 metres and includes a 665 metre vertical extent from 485mRL to -180mRL. Gold displays a strong association with sulphides and most abundant gangue minerals. Arsenopyrite, boulangerite and pyrrohotite are commonly associated with gold in variably boudinaged quartz and sulphide veins where the gold is found in fractures and as inclusions.

Gold is also seen as free grains in the silicate matrix of the host rock with feldspars, quartz and micas common hosts. The gold is generally fine grained ranging from 2µm to 40 µm.


Exploration at Fäboliden commenced in 1993 and has primarily involved drilling, with 333 holes, 64,784.47 metres drilled prior to Dragon Mining's acquisition of the project. In addition to drilling, other activities undertaken by the previous owners include test mining and processing, resource estimation and compilation of a Definitive Feasibility Study for a large tonnage low grade mining and processing operation.


Dragon Mining completed the conditional acquisition of Fäboliden in July 2015 and have completed a 34 hole Diamond core drilling program to evaluate the near surface, higher grade zone, improving the density of drilling in a select area to a nominal grid base of 25 by 25 metre and 25 by 50 metre basis over a strike length of approximately 400 metres.


The results from the drilling program showed that the high grade zone displays good continuity both down dip and along strike, the grades received from drilling commensurate with the results from historic drilling. Intercepts received have included the robust 4.00 metres @ 20.70 g/t gold, 7.00 metres @ 18.24 g/t gold, 14.00 metres @ 11.05 g/t gold, and 13.00 metres @ 8.37 g/t gold. All results were released to the ASX on the 29 July 2015 - High Grade Intercepts Received from the Fäboliden Gold Project and 15 September 2015 - Robust Results Highlight Potential at Fäboliden. Both of these releases are available at www.asx.com.au (ASX Code: DRA).

Summary of Information Material to Understanding the Reported Estimates


  • Geology and Mineralisation Interpretation

    The Fäboliden Gold Deposit is located within the Fennoscandian Shield, southwest of the Skellefte District in northern Sweden and is classified as an orogenic gold deposit.


    Gold mineralisation at Fäboliden is hosted by Paleoproterozoic meta-sediments and meta-volcanic rocks, surrounded by granitoids. The project geology is cross-cut by a set of northwest-southeast striking, flat lying undeformed dolerites which are not mineralised.


    Gold mineralisation is delineated over a strike length of 1,295 metres (from 7,169,125mN to 7,170,420mN) and includes a 665 metre vertical extent from 485mRL to -180mRL. It represents a multiple tabular style of mineralisation that dips at approximately 55° to the southeast in the southern portion of the deposit to near vertical in the northern portion of the deposit, with the strike of the deposit varying from NNE-SSW in the south to NNW-SSE in the north.


    Gold displays strong associations with sulphides and most abundant gangue minerals. Arsenopyrite, boulangerite and pyrrohotite are commonly associated with gold in variably boudinaged quartz and sulphide veins where the gold is found in fractures and as inclusions. Gold is also seen as free grains in the silicate matrix of the host rock with feldspars, quartz and micas common hosts. Gold is generally fine grained ranging from 2µm to 40 µm.


    All geological interpretations are based on lithology, alteration and mineralisation observations obtained from drill holes. The interpretation of the extent and geometry of the gold mineralisation is based on gold assays.


  • Drill Information and Sampling

    A total of 367 holes have been completed on the project to date, comprising 67,725.97 metres. The majority of drilling has been undertaken by Diamond core methods, with 11 holes completed by reverse circulation (RC) methods. Drill holes used in the Mineral Resource estimate included 8 RC holes and 206 Diamond holes for a total of 4,681m within the wireframes.


    Historical drilling has been undertaken on a nominal grid spacing of 50 metres by 50 metres for the near surface material, increasing to 100 metres by 100 metres and greater for the depth extensions. The recent drilling completed by Dragon Mining has improved the drill density to a nominal 25 metre by 25 metre and 25 metre by 50 metre basis for the near surface material over a strike length of 400 metres.


    Most drill holes were completed perpendicular to the strike of the deposit and drilled at dips between -35° and -75°. A small number of holes were drilled vertically. Historical core predominantly measured 36mm to 39mm (BQ) diameter, more recent historical drilling at 42mm to 49mm (NQ). Core from the Dragon Mining campaign measured 50.5mm (WL-66). Core recovery where measured, has corresponded well with expectations of drilling in unweathered crystalline bedrock.


    Historical drill hole collars have been surveyed to the Swedish National Grid system - RT90 2.5 gon väst (standard). A program of resurveying by independent survey consultants Tyrens AB, on behalf of Dragon Mining has verified the historical coordinates. New drill holes completed by Dragon Mining have been surveyed using a Trimble R8 GNSS device by independent survey consultants Tyrens AB.


    Down hole dip and azimuth deviations of historical holes were recorded using a Reflex Maxibor II tool on all holes completed since 2006, approximately 50% of all holes drilled. All drill holes completed by Dragon Mining were surveyed using a DeviFlex instrument for down hole dip and azimuth. The starting azimuth was resurveyed by GeoVista AB using a RTK-GPS.


    Diamond drilling was logged for a combination of geological and structural attributes. The core has been photographed and measured for RQD and core recovery. All Diamond logging data is entered into a Microsoft Excel spread sheet then imported into a Microsoft Access database.


    Prior to 1999 the entire core was submitted for crushing and analysis. Since 1999 the previous owners submitted half core samples for analysis. Samples were generally collected on metre intervals, though sample lengths have varied from 0.1 metres to 4.0 metres. Sample preparation was conducted by ALS Chemex in Piteå, Sweden, with sample pulps sent to various laboratories including Boliden Minesite Laboratory, SGS-Filab and ALS Chemex (Minerals).


    Reverse circulation drill hole samples were collected at 1 metre intervals. Samples were collected at the rig, representing the drill cutting's coarse fraction. A sub-sample was collected at the drill rig for analysis. Sample preparation was conducted by ALS Chemex in Piteå, Sweden, with sample pulps sent to ALS Chemex in Vancouver, Canada for analysis.

    Dragon Mining submitted half core samples to the ALS Minerals facility in Piteå, Sweden for sample preparation and analysis at the ALS Minerals facilities at Loughrea in Ireland for analysis for gold and multi-elements. Samples were generally collected at 1 metre intervals.


  • Sample Preparation and Analysis

    Historical sample preparation was conducted by SGS and ALS Chemex in Piteå, Sweden, with sample pulps sent to Boliden Minesite Laboratory, SGS-Filab and ALS Chemex (Minerals) in Vancouver, Canada for assaying for gold by 30gm or 50gm Fire Assay methods.


    Samples are weighed, assigned a unique bar code and logged into the ALS system. The entire sample was dried and crushed to 5mm. The entire sample was then pulverised to better than 85% passing 75 microns using a LM5 pulveriser. The pulverised sample is split with multiple feed in a Jones riffle splitter until a 100 gram sub-sample is obtained for analysis for gold and multi-elements.


    Analysis for gold by 50 gram fire assay fusion with an Atomic Absorption Spectrometry (AAS) finish. Silver was assayed using nitric acid and aqua regia digestion followed by atomic absorption spectrometry. Samples were also assayed by aqua regia digest followed by inductively coupled plasma optical emission spectroscopy for a suite of 33 elements.


    Samples from Dragon Mining drilling were submitted to the ALS Minerals facility in Piteå, Sweden for sample preparation. Half-core samples were weighed, assigned a unique bar code and logged into the ALS system. The entire sample was dried and crushed to 5mm. A sub-sample of the crushed material was then pulverised to better than 85% passing 75µm using a LM5 pulveriser. The pulverised sample was split with multiple feed in a Jones riffle splitter until a 100-200g sub-sample was obtained. The sub-sample was dispatched to the ALS Minerals facilities at Loughrea in Ireland for analysis for gold by 30g Fire Assay fusion with an Atomic Absorption Spectrometry (AAS) finish. Samples with gold values greater than 5g/t gold were re-analysed using 30g Fire Assay methods with gravimetric finish.


    The previous owners implemented a program of inserting certified reference materials representing six different standards ranging in gold grades from 0.43 g/t to 9.64 g/t gold in 2005. Insertion was completed at a rate of approximately 1 for every 188 samples submitted. Blank samples were inserted at a rate of 1 in 20 samples. The samples were submitted by the laboratory on behalf of the previous owners and are not considered blind. There was no systematic blind repeat sampling program implemented by the previous owners, the repeat pulp samples submitted being done at a rate of 1 sample for every 49 samples. No coarse duplicates samples were submitted by the previous owner.


    QAQC protocols were stringently adhered to throughout the duration of the drilling program undertaken by Dragon Mining. Dragon Mining included a certified reference standard, blank and pulp duplicate on a 1 in 20 basis. Analysis on coarse crush duplicates were undertaken at an umpire facility (Actlabs - Ancaster, Ontario and Kamloops, British Columbia) on a 1 in 10 basis. The primary laboratory, ALS Minerals implement an internal QAQC program that includes the insertion of blanks, certified reference material and duplicates with each analytical run.


  • Estimation Methodology and Classification

    This Mineral Resource estimate was compiled by independent mining consultants, RungePincockMinarco Limited in Perth, Western Australia and was reported in accordance with the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.


    Samples were composited to 1m based on an analysis of sample lengths inside the wireframes. High grade cuts were applied to the data based on statistical analysis of individual lodes and ranged between 15 g/t to 40 g/t gold.


    A Surpac block model was used for the estimate with a block size of 10m NS by 5m EW by 5m vertical with sub- blocks of 2.5m by 1.25m by 1.25m. This was selected as the optimal block size as a result of kriging neighbourhood analysis (KNA).


    Ordinary kriging (OK) grade interpolation was used for the estimate, constrained by Mineral Resource outlines based on mineralisation envelopes prepared using a nominal 0.5 g/t gold cut-off grade for low grade and 1.3 g/t gold for high grade, with a minimum down-hole length of 2 metres. Three passes were used to estimate the blocks in the model and more than 95% of blocks were filled in the first two passes.


    Bulk densities ranging between 1.8t/m3 and 2.97t/m3 were assigned in the block model dependent on lithology and weathering.

    The Mineral Resource was classified as an Indicated and Inferred Mineral Resource based on data quality, sample spacing, and lode continuity. The Indicated Mineral Resource was defined within areas of close spaced Diamond and RC drilling of less than 50m by 50m. The Inferred Mineral Resource was assigned to areas where drill hole spacing was greater than 50m by 50m, where small isolated pods of mineralisation occur outside the main mineralised zones, and to geologically complex zones.


  • Mining, Metallurgy and Other Modifying Factors

The Fäboliden Mineral Resource estimate will form the basis of a new Pre-feasibility Study. Detailed open-pit mining studies are currently in progress as part of this study. A second phase of bench scale test work is also advancing, this following an initial phase of bench scale test work and production scale test work completed by Dragon Mining in late 2014.


Historic metallurgical test work completed by the previous owners focussed on their preferred flow sheet proposal comprising a flotation circuit and cyanide leaching of concentrates. Metallurgical test work directed to leaching of whole rock material was limited, the work that was completed indicated that gold extraction levels were related to grind size.


As part of the due diligence process, Dragon Mining submitted a representative drill core sample from the near surface higher grade zone at Fäboliden, to ALS Metallurgy in Perth for bench scale comminution and leaching test work, using process parameters from Svartliden as reference. The test work program was managed by independent consultants Minnovo Pty Ltd, Perth.


The comminution results showed moderate hardness and abrasion, with a Bond ball mill work index of 15.3 kWh/t and an abrasion index of 0.2614. These results were not significantly dissimilar to those of earlier test work programs completed by the previous owner. Modelling of the Svartliden mill based on the obtained parameters showed that for a grind size of P80 53 µm, a throughput range of 33 to 42 t/hr should be achievable. Similarly, for a grind size of P80 106 µm a throughput range of 46 to 53 t/h should be achievable.


Contrary to the results of the historic leach test work, the new leach test work program did not show a strong correlation between grind sizes and leach extraction with extraction levels ranging from 70.3% to 84.4%. All tests completed displayed relatively fast leaching, with approximately 97% of the final gold extraction being achieved after 16 hours. Cyanide and lime consumption were moderate at approximately 1.0 kg/t and 0.3 kg/t, respectively.


Minnovo commented that the initial leach test conducted at P80 53 µm, which returned a gold extraction level of 84.43% appeared to be anomalous as the subsequent tests undertaken at this grind size failed to replicate the initial result. It was thus concluded that at the minimum grind size (P80 53 µm) considered achievable when processing at Svartliden, that gold extraction levels exceeding approximately 75% are unlikely for material from Fäboliden.


During the due diligence period, Dragon Mining also carried out a full scale production test of approximately 1,000 tonnes of higher grade gold bearing material from Fäboliden at the Svartliden Plant. This material was excavated during the previous owner's 2005 test mining and processing program and stockpiled at surface. The production test confirmed the results of the new bench scale leach test work, yielding a head grade of 3.02 g/t gold and a gold extraction level of 79.4%.

Commentary

Sampling techniques

  • Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

  • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

  • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.

The Fäboliden deposit has been sampled by a series of Diamond core and reverse circulation drill holes completed from surface, as well as test mining and processing.


A total of 322 Diamond core drill holes and 11 reverse circulation holes have been completed by the previous owners. A total of 98 blast holes were also drilled to carry out the test mining.


Dragon has completed 34 WL-66 Diamond core drill holes for a total advance of 2,941.50 metres.


Historical drilling has been completed on a nominal grid spacing of 50m by 50m for the near surface material, increasing to 100m by 100m and greater for the depth extensions.


The drilling completed by Dragon has improved the drill density to a nominal 25m by 25m and 25m by 50m basis for the near surface material, over a strike length of 400m.


The previous owners completed a program of test mining in 2005, targeting a zone of near surface higher grade mineralisation immediately north of Dragon's drilling area, with the excavation of three trenches.


Historic drill hole collars have been surveyed to the Swedish National Grid system - RT90 2.5 gon väst (standard). Details of the survey process, equipment used, who performed the surveys or the level of accuracy of the survey has not been documented. A program of resurveying by independent survey consultants Tyrens AB, on behalf of Dragon has verified the historical coordinates.


New drill holes have been surveyed using a Trimble R8 GNSS device by independent survey consultants Tyrens AB.

spreadsheets and then transferred to a Microsoft Access database.


Prior to 1999 the entire core was submitted for analysis. Since 1999 half core samples have been analysed. Samples were generally collected on metre intervals, though samples have varied from 0.1m to 4m.


Half core samples of select zones of core from the Dragon drilling program was submitted to the laboratory. Sampling was completed on a one metre basis.


Sample preparation of historic samples was conducted by ALS Chemex in Piteå, Sweden, with sample pulps sent to ALS Chemex in Vancouver, Canada for assaying for gold by 50 gram Fire Assay methods. Samples were also assayed by aqua regia digest followed by inductively coupled plasma optical emission spectroscopy for a suite of 33 elements.


Dragon samples were prepared at the ALS Minerals facility in Piteå, Sweden. Sample pulps were sent to the ALS Minerals facility in Loughrea, Ireland for assaying for gold by 30g Fire Assay methods (Au- AA25) and multi-elements by ME-ICP41. Samples with gold values greater than 5g/t Au were re- analysed using 30g Fire Assay methods with gravimetric finish (Au-GRA 21).

Drilling techniques

  • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of Diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc).

Diamond core drilling has been the primary drilling method used at Fäboliden. The majority of the historic drilling was completed using 36mm to 39mm core diameter, more recent drilling completed using 42mm to 49mm (NQ) diameter.


Historical hole depths ranged from 41.6m to 762m.


Core was collected with a standard tube. There is no record to indicate that core orientation was undertaken on all of the historical holes.


Down hole dip and azimuth deviations were recorded using a Reflex Maxibor II tool on all holes completed since 2006, approximately 50% of all holes drilled.


The recent drilling completed by Dragon was completed using WL-66, with hole depths ranging from 35 to 162m.


Core was collected with a standard tube and all holes except the first hole were fully orientated.

core blocks.


Core recoveries were routinely recorded during the RQD logging process.


Core recovery has been excellent and corresponded well with expectations of drilling in unweathered crystalline bedrock.


Experienced local drilling contract groups undertook the drilling completed by the previous owners and Dragon.


No relationship has been noted between sample recovery and grade.

Logging

  • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.

  • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.

  • The total length and percentage of the relevant intersections logged.

Detailed geological logging was undertaken on all drill core. The core was logged using 286 codes, made up of 77 lithology codes, 5 intensity codes, 97 structural codes, 82 mineralisation codes and 25 general codes. Logging was performed to a level that will support Mineral Resource estimation.


Drill samples were logged for lithology, mineralisation and alteration. Logging was a mix of qualitative and quantitative observations. The core was systematically photographed by hand.


All holes were logged in full.

Sub-sampling techniques and sample preparation

  • If core, whether cut or sawn and whether quarter, half or all core taken.

  • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.

  • For all sample types, the nature, quality and appropriateness of the sample preparation technique.

  • Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples.

  • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.

  • Whether sample sizes are appropriate to the grain size of the material being sampled.


Prior to 1999 the entire core was submitted for analysis. Since 1999 half core samples have been analysed. Drill core was cut by saw.


Drilling completed by the previous owners was completed primarily by Diamond core methods.


Reverse circulation drill hole samples were collected at 1m intervals. Samples were collected at the rig, representing cutting's coarse fraction. A sub-sample was collected at the drill rig for analysis. There is no information available describing the sub-sampling process or the quality of the sample.


Drilling completed by Dragon was completed by Diamond core methods.


Sampling of Diamond core samples used industry standard techniques.


Drill core is sawn in half using a core saw.


With respect to the nature of the mineralised system and the core diameter the use of half-core is considered appropriate.


Sample preparation is completed by ALS Minerals and follows industry best applicable practice. ALS Minerals procedures and facilities are organised to assure proper preparation of the sample for analysis, to prevent sample mixing, and to minimise dust contamination or sample to sample contamination.


Samples are submitted to the ALS Minerals facility in Piteå, Sweden for sample preparation.


Criteria JORC Code explanation Commentary

Half core samples are weighed, assigned a unique bar code and logged into the ALS system. The entire sample is dried and crushed to 5mm. A sub-sample of the crushed material is then pulverised to better than 85% passing 75 microns using a LM5 pulveriser. The pulverised sample is split with multiple feed in a Jones riffle splitter until a 100-200g sub-sample is obtained for dispatch to the ALS Minerals facilities at Vancouver in Canada for analysis for gold and multi- elements for the historical samples and Loughrea in Ireland for gold and multi-elements for the Dragon samples.


All sub-sampling is carried out at the ALS Minerals facility in Piteå, Sweden.


Core sample intervals are measured and clearly marked on core. Core is sawn in half longitudinally and at the start and finish of each individual sample.


ALS personnel were trained to carry out the sampling of the Dragon drill core, in accordance with Dragon protocols.


Certified reference material and blanks were routinely inserted with the sample submission, at a rate of 1 sample every 20 samples. Results have returned in accordance with expected values, apart from one sample that returned a value outside the acceptable levels. This has been fully checked by the Company and the laboratory and it has been concluded that the original results was incorrect from follow-up analysis. Additional check work has been instigated by the Company.


Certified reference materials were not routinely inserted with the sample submission by the previous owners. The small database available returned an acceptable level of bias from the laboratory. Blank samples were inserted at the rate of 1 in 20 by the previous owners, the results indicating that there is little evidence of contamination between samples.


Analysis of coarse crush duplicates has not been performed by the previous owners. Dragon has commenced a program of check analysis on coarse crush duplicates. Results from the initial batch returned values commensurate with the primary analysis. Results are pending from the second batch.


The method selected for sample preparation is considered appropriate to correctly represent the style of mineralisation, the thickness and consistency of the intersections, the sampling methodology and assay value ranges for gold.

ALS Minerals are a certified global laboratory group. They are monitored by an internal QAQC program and a QAQC program implemented by Dragon, both of which include the inclusion of blank material, duplicates and certified reference material.


The analytical methods used for gold are considered total.


The analytical work is undertaken at a level suitable for inclusion in Mineral Resource estimates.


No geophysical tools were used for analytical purposes on sample material from Fäboliden.


QAQC protocols were not stringently adhered to throughout the duration of all drilling programs undertaken by the previous owners.


The previous owners implemented a program of inserting certified reference materials (sourced from Ore Research and Exploration and supplied by Analytical Solutions Ltd from Toronto, Canada) representing six different standards ranging in gold grades from 0.43 g/t to 9.64g/t Au in 2005. Insertion was completed at a rate of approximately 1 for every 188 samples submitted.


Blank samples were inserted at a rate of 1 in 20 samples. The samples were submitted by the laboratory in behalf of the previous owners and are not considered blind.


There was no systematic blind repeat sampling program implemented by the previous owners, the repeat pulp samples submitted being done at a rate of 1 sample for every 49 samples.


No coarse duplicates samples were submitted by the previous owners.


QAQC protocols were stringently adhered to throughout the duration of all drilling programs undertaken by Dragon.


Dragon included a certified reference standard, blank and pulp duplicated on a 1 in 20 basis. Coarse crush duplicates are being undertaken at an umpire facility on a 1 in 10 basis.


ALS Minerals implement an internal QAQC program that includes the insertion of blanks, certified reference material and duplicates with each analytical run.


A review of the previous owners QAQC results has shown reasonable consistency between different laboratories, analytical methods and results.


The results for Dragon have yielded values as expected to date, apart from one sample that returned a value outside the acceptable levels. This has been fully checked Dragon and the laboratory and it has been concluded that the original results was incorrect from follow-up analysis. Additional check work has

been instigated by Dragon.

Verification of sampling and assaying

  • The verification of significant intersections by either independent or alternative company personnel.

  • The use of twinned holes.

  • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.

  • Discuss any adjustment to assay data.

Dragon has no knowledge of the procedures implemented by the previous owners to verify significant intersections.


Significant intersections are verified by Dragon geologists.


The previous owners reverse circulation program was implemented to twin some of the Diamond core drill holes.


Dragon has not twinned any holes.


Primary data was collected by the previous owners and Dragon personnel.


All measurements and observations were recorded into an Excel spreadsheet. Primary assay and QAQC data is entered into an Excel spreadsheet.


No adjustment has been made to assay data.

Location of data points

  • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.

  • Specification of the grid system used.

  • Quality and adequacy of topographic control.

Details of the survey process, equipment used, who performed the surveys or the level of accuracy of the survey was not been located during the due diligence process completed by Dragon.


A program of resurveying by independent survey consultants Tyrens AB, on behalf of Dragon has verified the historical coordinates.


New drill holes have been surveyed using a Trimble R8 GNSS device by independent survey consultants Tyrens AB.


Historic down hole dip and azimuth deviations were recorded using a Reflex Maxibor II tool on all holes completed since 2006, approximately 50% of all holes drilled.


All drill holes completed by Dragon were surveyed using a DeviFlex instrument for down hole dip and azimuth. The starting azimuth was resurveyed by GeoVista AB using a RTK-GPS.


The grid system used for the reporting of results is the Swedish National Grid System RT90 2.5 gon väst (standard).


Details of the topographic control over the Fäboliden deposit were not obtained by Dragon. Dragon is yet to establish specific topographic control over the Fäboliden Gold Project.


The survey methodology and equipment utilised during the collar surveys provides sufficient detail and accuracy for the topographic control as needed for inclusion in Mineral Resource estimates.

Data spacing and distribution

  • Data spacing for reporting of Exploration Results.

  • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation

Historic drilling has been undertaken from surface on a nominal grid base of 50m by 50m for the near surface material and 100m by 100m and greater for the material at depth.
