"The assay results from the first seven holes appear to confirm the resource within the eastern portion of the Lundberg deposit and the drilling program continues on plan," commented Warren Macleod, President and Chief Executive Officer of Buchans Minerals.
The drilling program has been designed with multiple objectives, which include: (1) the upgrade of a substantial portion of the current inferred resource to an indicated category; (2) seeking to expand a number of higher grade areas within the conceptual open pit, specifically both the near surface "Engine House" deposit and also beneath the old "Lucky Strike Glory Hole"; and (3) seeking to expand the potential size of the Lundberg deposits with step-out exploration holes.
The Lundberg Deposit
The Lundberg deposit is a stockwork-type volcanogenic massive sulphide ("VMS") deposit surrounding and extending from the old Buchans mine, containing lower grade zinc, copper, lead and minor silver. The current Inferred Resource within the Lundberg conceptual open pit as defined by Wardrop Engineering, a Tetra Tech Company ("Wardrop"), is estimated as 17.28 million tonnes with average grades of 1.63% zinc, 0.69% lead, 0.40% copper, and 5.96 gpt silver.
The Lundberg deposit was assessed by a positive Preliminary Economic Assessment ("PEA") completed by Wardrop in 2011 that identified the deposit has the potential to become a stand-alone 5,000 tonne per day mine. The PEA is available for viewing on the Company's website and a summary of the PEA can be read from the Company's news release August 11, 2011.
Minco Joint Venture Agreement
On April 30th, 2012, Buchans Minerals and Minco announced an agreement granting Minco the right to earn a 51% interest in the Company's base metal properties in central Newfoundland by spending $8 million to advance the Lundberg deposit to final feasibility over four (4) years and further explore the Company's extensive mineral properties in the region.
Minco is required to spend $3.5 million over the next two years to advance the project to the pre-feasibility stage. During this period Minco plans to undertake a range of development activities that will include drilling, resource estimation, geotechnical engineering, open-pit mine plan, metallurgy, plant design, engineering, environmental studies and an economic evaluation. Following the expenditure of $3.5 million, Minco will have the option to proceed to complete a final feasibility study by spending a further $4.5 million over the following two years.
Qualified Person
The drill program is being supervised by Buchans Minerals Corporation. Drill intercepts quoted are core lengths and true widths have not been estimated due to the stockwork and disseminated nature of mineralization intersected, although previous drilling suggests the mineralization consists of a flat-lying "stratigraphically controlled blanket". Paul Moore, M.Sc., P.Geo., (NL), Buchans Minerals' Vice President of Exploration, is acting as Qualified Person in compliance with National Instrument 43-101 with respect to this release and has reviewed the contents for accuracy.
Sampling Procedure
All drill core was logged and sampled by Buchans Minerals geological and technical staff with cores descriptively logged on site, aligned, marked for sampling and split longitudinally using a Diamond saw. Samples consist of quartered NQ-size Diamond core (47.6 mm diameter core). Three quarters of the core are preserved in core boxes for future reference. As part of Buchans Minerals' QAQC protocols, samples comprising quartered core were bagged, tagged, sealed and delivered directly to Eastern Analytical Limited's laboratory in Springdale by Buchans Minerals' personnel. Samples are nominally one metre in length, except where specific geologic parameters required a different interval be sampled. Sample preparation was completed by Eastern Analytical with each sample crushed to approximately -10 mesh and split using a riffle splitter to approximately 300 g. Each sample split was pulverized using a ring mill to approximately 98% -150 mesh. In addition to regular samples, blank samples (one per 20 samples) and certified standards (one per 20 samples) were also submitted for sample preparation and assay.
All assays were completed by Eastern Analytical of Springdale Newfoundland by the inductively coupled plasma method (ICP-30) for base metals (Cu, Pb, Zn) and to Ore Grade Assay Cu, Pb and Zn if upper detection limits by ICP were exceeded for either element (upper detection limits; Cu 10,000 ppm, Pb 2,200 ppm, Zn 2,200 ppm).. ICP analyses were completed using a 0.500 g sample digested in nitric and hydrochloric acid and analyzed by ICPOES (Inductively Coupled Plasma Optical Emission Spectroscopy). Base metal Ore Grade Assays (Cu, Pb, Zn) were completed using a 0.200 g sample digested in nitric and hydrochloric acid and analyzed by the atomic absorption (AA) method. Silver assays were completed using a 1,000 mg sample digested in hydrochloric and nitric acid and analyzed by AA. Gold assays were completed by standard � assay ton fire assay using the AA method. All samples analyzed by the Ore Grade Assay method are ultimately re-assayed as check assays by ALS Canada Limited of Vancouver, BC. Eastern and ALS also implement independent QAQC protocols that include insertion of blanks and certified CanMet standards as part their routine analyses.
