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.
