Vancouver, British Columbia (FSCwire) – Tosca Mining Corp (TSQ-TSX-V, TSMNF:OTCBB, TQ4:FSE), announces that it has received analytical results from core samples obtained from a recently completed drill program on its Carol Copper project, located in Sonora, Mexico.

Six drill holes, totaling of 577 metres, were drilled to investigate the continuity and extent of skarn mineralization encountered in surface trenches and outcrop. Drilling tested a target area measuring 875 metres in length.

All holes encountered moderately to strongly altered skarn zones. The Company is in the process of correlating surface data with the drill results. 

A total of 400 samples (including blanks and standards) were sent for analysis with core samples ranging in length from 0.5 to 2 metres.  Values received ranged from trace to 0.288 g/t gold, trace to 9.2 g/t silver, trace to 2.39% copper, trace to 0.10 % lead and trace to 1.06 % zinc.

In general, mineralization is localized over narrow widths. The widest intervals encountered in core were from hole 5, which intersected 0.98 % zinc over 2 metres from 6 to 8 metres depth and 0.29 % copper over 3 metres from 26 to 29 metres depth.

Fracture controlled mineralization combined with geochemistry indicates that the skarn formation was subjected to significant leaching and subsequent remobilization that has resulted in the copper/silver/gold/lead/zinc mineralization being concentrated in a zone at or near surface.  The controls on the location of the higher grade mineralization intersected in the trenches remains to be fully understood.

About the Carol Copper Project

The Carol Copper project covers over 750 hectares and is located in southern Sonora State, Mexico. It is approximately five km northeast of the producing Piedras Verdes copper mine, Mexico’s third largest. Tosca has the right to acquire a 100 percent interest in the Carol project under an option agreement further described in its Oc. 14, 2013, news release.

Ian Foreman, P.Geo., president of Alta Vista Ventures and independent to Tosca, is the Qualified Person, as defined by NI 43-101, for the Carol Project and is responsible for the technical information in this news release.

Samples from Carol were prepared and analyzed by IPL Inspectorate in their facilities in Mexico and Vancouver, respectively.  Samples generally consisted of 1-3 kg of material.  Gold, silver, copper, lead and zinc were analyzed as part of a multi-element ICP package using an aqua regia digestion.  Over limit samples with greater than 1% Cu, Pb and Zn were re-analyzed using ore grade detection limits.
