VANCOUVER, British Columbia, Nov. 14, 2012 /PRNewswire/ -- Teryl Resources Corp. (TSX Venture Exchange: TRC.V, OTCBB: TRYLF) and Minewest Silver and Gold announce that analytical results from the 2012 Silverknife Ag-Zn-Pb core re--sampling project in north central B.C. have been received and compiled by the Company and confirm historically reported mineralization. Additionally, the 2012 program has defined high priority drill targets for a fully permitted 2013 diamond drilling program targeting extension to the known Ag-Zn-Pb mineralization.
During the course of the 2012 Silverknife program, the Project was accessed and the 25+ year old core storage site was re-established with all recoverable core re-boxed, re-logged, and where practicable mineralized intervals and proximal area were re-sampled. It is estimated that 85% of the historic core was resurrected and restored. Specific representative intervals of Ag-Zn-Pb mineralization were selected for detailed Inspection and any germane previously sampled intersections of core were quartered and previously un-sampled core intervals were halved. Due to core loss and degradation over the intervening years, exact duplication of previously sampled intervals was not always possible, where practicable however, the 2012 sampling was conducted on systematic 1 metre intervals
The 2012 core re-Iogging and re-sampling program confirmed the grade and tenor of mineralization previously identified on the Silverknife Project with grades from trace to 21.19 ounces/ton (726.8 ppm) Ag with an average of 1.79 ounces/ton (61.36 ppm) Ag; trace to 16.48% Zn with an average of 1.99% Zn; trace to 10.98% Pb with an average of 0.87% Pb; and from trace to 1.1 ppm Au. A comparison of the historic analytical results to the 2012 analytical results do not show an exact 1:1 ration, however owing to the style of mineralization (coarse grained sphalerite and galena) and the disparate analytical techniques and sampling intervals, this variation Is expected.
It was noticed by Company geologists during the re-Iogging of the core that where visible Ag-Zn-Pb mineralization was identified, a corresponding drop in core recovery was common. This observation is exceedingly valuable, as this rack of core recovery within mineralized sections is indicative of a potential understatement of grade. The Company is confident that armed with this information, more care can be taken when drill testing these areas, and potentially with such care reported grades will increase.
In total 101 core samples were collected and submitted for assay to Inspectorate Exploration and Mining Services Inc., of Richmond. BC, an ISO 9001:2008 certified laboratory. Samples were shipped by Company consultants to Inspectorate's Whitehorse, YT preparation facility where samples were sorted and crushed to appropriate particle size (pulp) and representatively split to a smaller size for shipment to Inspectorate's, Richmond, B.C. analysis facility. Assay procedures consisted of 30 element Inductively Coupled Spectrophotometry (ICP) following multi-acid digestion as well as standard fire assay for gold, with atomic adsorption (AA.) finish. When overlimits were reported, Inspectorate's Ore-Grade analyses for Ag, Pb, and Zn; respectively, was utilized. Assay standards were inserted into the sample stream as part of the Silverknife OA/OC program.
A detailed GPS survey of the historic SlIverknife "Discovery" drill out was conducted during the 2012 program coincident with an updated Silverknife mineral claim Boundary survey. With the data collected and compiled from the 2012 program, the Company will now intends to digitize the historic drilling data and model the Silverknife mineralization with the help of 3D geological modeling software. This work will allow the Company to define the extent of the defined mineralization, target 2013 drill holes and focus exploration efforts on extending and expanding the Silverknife Ag-Zn-Pb mineralization through diamond drilling.
