Golden Predator Files Technical Report on Brewery Creek Project
TSX: GPD
VANCOUVER, June 18, 2012 /CNW/ - Golden Predator Corp. (TSX:GPD) (the "Company") is pleased to announce that further to its press release dated May 1, 2012, the Company has filed a National Instrument 43-101 Technical Report detailing Indicated and Inferred Mineral Resource estimates on its flagship Brewery Creek Project, located in the Yukon, Canada. The Technical Report along with further information on the project can be found under the Company's profile on SEDAR at www.sedar.com and on the Company's website at www.goldenpredator.com.
Indicated Mineral Resources are estimated at 20.4 million tonnes grading 0.89 g/t gold containing 581,000 ounces of gold and Inferred Mineral Resources are estimated at 13.0 million tonnes grading 0.83 g/t gold containing 346,000 ounces of gold. Cut off gold grade values of 0.20 g/t gold for oxide material and 0.70 g/t gold for sulfide material were implemented.

(1) | The Brewery Creek Resource Estimate includes six separate zones of mineralization and each zone was estimated with different gold grade capping values as follows; Big Rock 6.0 g/t, Fosters-Canadian 12.0 g/t, Bohemian-Schooner 22.5 g/t, Sleeman 16.0 g/t, North Slope 15.0 g/t, Classic 3.5 g/t. The following estimated parameters were used to determine the cut off grades for oxide and sulphide material; gold price $1500/oz, oxide recovery 65%, sulfide recovery 75%, open pit mining costs $2.00/tonne, oxide heap leach process costs $3.50/tonne, sulfide milling process costs $23.00/tonne and G & A costs $1.16/tonne. Tonnes and contained ounces have been rounded to the nearest 1,000. |
The Mineral Resources for the Company's Brewery Creek Project were estimated by EBA, a Tetra Tech Company (EBA), utilizing the Company's drilling and sampling programs, together with independently validated historic sampling and drilling data conducted by previous operators including Loki Gold Corp., Viceroy Minerals Corp. and Alexco Resource Corp. Gemcom (GEMS) modelling software was used to complete the resource estimations and conform to guidelines and definitions established by National Instrument 43-101 and the Canadian Institute of Mining and Metallurgy.
To complete the resource estimations, a total of 54,822 samples from 1,244 drill holes, totalling 106,650 metres (34,929 samples from 957 RC holes, totalling 67,689 metres, and 19,983 samples from 287 core holes, totalling 38,981 metres) were composited to 2 metre lengths and interpolated into six separate GEMS partial block models. Ordinary Kriging (OK) methodology was applied to interpolate gold grades for the Big Rock, Bohemian-Schooner, Fosters-Canadian and North Slope Deposits, and Inverse Distance cubed (ID3) methodology was applied to interpolate resources for the Classic Deposit. Oxide resources were defined by partial or full blocks lying above an interpreted reduction-oxidation (redox) boundary supplied by the Company and based on actual drill hole logs.
Project Geology
Cretaceous-age quartz monzonite sills and subordinate lower Paleozoic silici-clastic sedimentary strata, host epithermal-style gold mineralization at Brewery Creek. En echelon style quartz veinlets and stockworks cut the pervasively clay-altered and locally silicified intrusions. Areas of elevated gold concentration relate directly to zones of concentrated quartz veining, though most of the lower-grade material occurs as disseminations in the altered and strongly limonitic intrusions. Trace elements associated with gold mineralization include arsenic, antimony and mercury, and unoxidized sulphide -bearing portions of the deposits commonly contain abundant pyrite and stibnite. Resources are reported from six zones which are mostly open to expansion in one or more directions laterally as well as at depth. Ongoing exploration has been designed to increase known resources as well as to identify new resource areas within the project area.
Project Overview
The Brewery Creek Project was operated by Viceroy Gold from 1996 to 2002 as an open pit operation with run-of-mine material delivered to the heap leach pad with approximately 280,000 ounces of gold recovered. Historic overall gold recovery from the heap leach operation is estimated at approximately 60%. Historic reports indicate that run-of-mine material included preg-robbing material was placed on the heap leach which reduced ultimate recoveries. The Company is undertaking a metallurgical characterization program to properly determine gold recovery profiles and preg-robbing characteristics by mineralized area and rock type. The program will include large diameter core drilling in the summer of 2012 for use in column leach tests. Data indicates that the preg-robbing material is predominantly restricted to sedimentary rocks which can be visually identified and, if necessary, selectively removed from material reporting to a process facility.
