Mustang Announces Increase to Mayville Resource
(firmenpresse) - TORONTO, ONTARIO -- (Marketwire) -- 02/20/13 -- Mustang Minerals Corp. (TSX VENTURE: MUM)(FRANKFURT: NJF) ("Mustang" or the "Company") today announced the results of a National Instrument 43-101 compliant resource estimate for its Mayville Deposit located in southeastern Manitoba. Indicated resources increased significantly from the resource estimate announced April 15, 2010. The indicated resource announced in 2010 was 11.6 million tonnes at 0.55% copper and 0.21% nickel which increased to 24.3 million tonnes at 0.45% copper and 0.19% nickel (0.69% copper equivalent). Inferred resources increased from 0.2 million tonnes at 0.55% copper and 0.2% nickel in 2010 to 4.1 million tonnes at 0.45% copper and 0.18% nickel (0.68% copper equivalent). The updated resource estimate was reported at a $20 NSR cut-off.
A substantially larger mineral resource at Mayville provides a positive catalyst for development of the Makwa and Mayville Deposits. The Company has announced that it plans to complete a Preliminary Economic Assessment based on co-development of the two deposits. The Mayville Property in particular has excellent exploration potential and remains open at depth and along strike. The Mayville and Makwa deposits are located within Mustang's mineral tenements in the highly prospective Bird River Greenstone Belt - an emerging area prospective for nickel, copper and platinum group metals.
Details of the resource estimate are as follows:
MINERAL RESOURCE ESTIMATE SUMMARY
In the area of the M2 deposit, the Mayville drill hole database includes 103 diamond core holes totalling 24,138 m. Drill sections are spaced 50 m apart along strike with intercepts on each section averaging 50 m apart down dip. A set of three-dimensional wireframe models of the mineralized zones were interpreted in cross section and plan views using the descriptive logs, a minimum NSR value of C$15 per tonne, and a minimum true thickness of two metres. Prior to compositing to two metre lengths, assays were capped to 2.5% Cu, 1.5% Ni, 0.40 g/t Au, 0.35 g/t Pt, and 0.70 g/t Pd. Block grades were estimated using the inverse distance squared interpretation algorithm. A global density of 3.0 t/m3 was assigned to the material contained within the wireframe models. Mineral Resources are reported within a preliminary pit shell generated in Whittle software.
Within the updated resource block model, the low concentrations of the precious metals (Au, Pt, and Pd) are such that they do not contribute to the NSR value due to typical treatment and refining terms and penalties. While they have no influence on the cut-off value and reported resource tonnage, they are estimated on the assumption that local higher grade zones may be present within the resource area. These higher grade areas do contribute to the Whittle pit optimization process using the assumed treatment and refining terms and conditions and may potentially offer revenue enhancement at some future point.
Exploration
Mustang will shortly commence drilling along strike of the Mayville Deposit to follow up on a recent step out hole approximately 200 meters east of the resource that intersected 18.53 meters of 0.56% copper and 0.16% nickel (see press release dated December 12, 2012). The objective of future drilling will be to look at the potential for on strike incremental tonnage at Mayville. Targets along an approximately one kilometer strike extension will be tested.
Current mineral reserves and mineral resources at Mustang's two deposits are:
Makwa Ni-Cu Deposit
NI 43-101 Probable Mineral Reserve Estimate of 9.86 million tonnes containing 0.541% nickel, 0.113% copper 0.433 g/t combined PGM. (reserve estimate completed February 2010 by Micon International Limited)
Mayville Cu-Ni Deposit
NI 43-101 Indicated Mineral Resource estimate is 24.3 million tonnes containing 0.45% copper, 0.19% nickel. Inferred mineral resource estimate is 4.1 million tonnes containing 0.45% copper and 0.18% nickel. (Feb. 2013 RPA Inc.)
