Microsoft Word - 150930 FINAL Pahtohavare Drilling Update
ASX & MEDIA ANNOUNCEMENT
Pahtohavare Assay Results
30 September 2015
Further wide, high-grade copper-gold-silver assays from the Central deposit at the Pahtohavare Cu-Au Project including the following intercept from PADH15006:
o 12.3m @ 2.99% Cu, 0.87g/t Au, 1.66g/t Ag from 29.2m (1% Cu lower-cut, 0m internal dilution)

Hannans Reward Ltd (ASX:HNR) is pleased to announce additional diamond drillhole assay results from the Central deposit at the Pahtohavare Cu-Au Project. Pahtohavare comprises three deposits, namely Central, Southern and South Eastern and is located approximately 8km south-west of Kiruna, a full service mining town in northern Sweden (refer Figure 4 below).
Hannans' Swedish joint venture partner Lovisagruvan AB (AktieTorget: LOVI) is funding the costs of exploration pursuant to the Joint Venture announced to ASX on 27 March 2015 with Hannans to retain a 25% free carried interest through to a Decision to Mine. The assay results reported below have been reviewed by Mr Stefan Sädbom, Exploration Director, Lovisagruvan AB and the announcement has been approved for release by Lovisagruvan AB. The Joint Venture exploration drilling program at Central was planned and managed by Amanda Scott, Exploration Manager, Hannans Reward Ltd.
Assay results have now been received for drillholes PADH15006 and also the diamond tail PARC13001D which include significant copper-gold-silver intercepts of:
PADH15006
30.43m @ 1.75% Cu, 0.49g/t Au, 1.54g/t Ag from 20.07m (0.1% Cu lower-cut, 1m internal dilution)
Inc. 12.3m @ 2.99% Cu, 0.87g/t Au, 1.66g/t Ag from 29.2m (1% Cu lower-cut, 0m internal dilution)
PARC13001D
-
18m @ 1.48% Cu, 0.36g/t Au, 0.9g/t Ag from 155m (0.1% Cu lower-cut, 1m internal dilution)
-
9m @ 0.49% Cu, 0.15g/t Au, 0.71g/t Ag from 176m (0.1% Cu lower-cut, 1m internal dilution)
The original RC assay intercept3 from PARC13001 was:
-
3m @ 4.02% Cu, 0.75g/t Au, 4.67g/t Ag from 129m (0.1% Cu lower-cut, 1m internal dilution)
Note that all widths are downhole widths as true widths are not currently known. Full drillhole information is provided in Tables 1 and 2 below.
Drillhole PADH15006, located on infill Profile F (refer Figure 2 below), was drilled towards the west which is perpendicular to the dip of the lithology. Profile F is a new infill (25m) profile and the mineralisation in PADH15006 confirms that the high-grade, strongly oxidised copper-gold-silver mineralisation continues along strike from between Profiles 6 & 7.

Refer ASX Announcement dated 17th July 2013 for more information regarding the drilling results for PARC13001 including JORC Table 1 information.
The main zone of mineralisation in PADH15006 is hosted within strongly goethite altered (oxidised/weathered) tuffaceous units. In addition to the main copper mineralised zone there are several narrower sub-economic (
In 2013, the first hole of an 8 hole RC programme was abandoned at 141m after encountering difficult drilling conditions. As part of the recent diamond drilling programme, the hole (PARC13001) was re-entered and a diamond tail was completed to a total depth of 235.3m. The hole intercepted copper-gold-silver mineralisation within a strongly goethite altered (oxidised/weathered) tuffaceous unit. As with PADH15005 (previously reported) and PADH15006, the highest grade copper mineralisation is associated with a very distinct strongly goethite altered and vughy breccia (refer Figure 3 below) where the secondary copper mineralisation (chrysocolla and malachite) is commonly present as matrix-fill. No significant primary copper mineralisation was intercepted at depth within PARC13001D although the hole terminated in a strongly altered skarn unit, typical of the Kiruna area but not previously seen at Pahtohavare.
Figure 3: High-grade copper mineralisation (malachite and chrysocolla) within strongly goethite altered breccia (PADH15005), Pahtohavare Copper-Gold Project, northern Sweden.
All drillholes from the recent diamond drilling programme have now been logged, sampled and dispatched to the laboratory for assaying; the balance of results is expected in October.
Joint venture partner Lovisagruvan AB is expected to make a decision on whether to proceed to Stage 2 of the joint venture agreement in late October.
The Central deposit contains a current JORC Compliant Inferred Mineral Resource Estimate6 of 1.4Mt at 1.8% Cu and 0.6 g/t Au (2.4% CuEq7).
6 Refer ASX Announcement dated 31st January 2014 for more information regarding the resource estimate including JORC Table 1 information.
7 Copper equivalent (CuEq) has been calculated using metal selling prices of USD$3.56 / lb for Cu and USD$1,510 / Oz for Au, along with metal recoveries of 90% for Au and 65% for Cu in sulphide material and 80% for Au and 50% of Cu in oxide material. The following equations were used:
-
Oxide: CuEq = (1.12 x Au (ppm) grade) + (0.98 x Cu% grade)
-
Sulphide: CuEq = (0.97 x Au (ppm) grade) + (0.99 x Cu% grade)
It is the company's opinion that the copper and gold metals used in the metal equivalent calculation have a reasonable potential for recovery and sale based on historical metallurgial testwork and previous mining.

Sampling techniques
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole 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
Sampling method is half-core sampling of HQ3 diamond drill core. Quarter-core sampling utilised where a duplicate samples have been taken.
Sampling was carried out under Hannans' sampling protocols and QAQC procedures as per industry best practice.
Diamond drilling completed using HQ3 coring equipment. Drillholes have been sampled on geological intervals (0.5-2.0m). All samples have been crushed, dried and pulverised (total prep) to produce a sub sample for multi-element analysis by four acid digest with ICPMS/OES and fire assay and AAS for gold.

Geology

Deposit type, geological setting and style The mineralisation at the Central of mineralisation. deposit has been classified as epigenetic copper-gold. Whilst the ore
appears to be preferentially located within a brecciated, highly altered (silica-albite) and oxidised felsic tuff, recent drilling (RC in 2013 and current diamond drilling) by Hannans has shown that copper mineralisation also occurs in the black graphitic shales sitting stratigraphically above the felsic tuff and also in the mafic sill (gabbro) which dominates the footwall. It has become apparent from the current drilling programme that there is a strong supergene control on secondary mineralisation in addition to lithological and structural controls. A new geological interpretation is required for the Central deposit as a result of the current drilling.
