VANCOUVER, Nov. 20, 2014 /CNW/ - During the summer, 2014, WMR ("the Company") conducted a follow-up program of exploration at the 100% owned Sierra Breccia target discovered in 2013 (See WMR Press Release 13-05 of October 18, 2013 for details, including analytical methods). The breccia zone has been traced for a length of approximately 200 meters in a series of four equally spaced historic (1950's?) mined-out pits and trenches. The steeply-dipping breccia zone has a vertical extent of 70 meters over the known strike length, and is hosted in a rhyolite sequence of Tertiary volcanic rocks. The Sierra target lies 700 meters above the Company's porphyry intrusion El Cobre exploration target.
The Sierra hydrothermal breccia contains high grades of copper, silver and gold where seventeen grab samples averaged 4.8% Cu, 101 g/t Ag and 4.4 g/t Au (see Press Release WMR 13-05, October 18, 2013) as well as high sulphidation system geochemical signatures anomalous in the elements iron, barium, bismuth and mercury.
Sierra Trench One is located at the lowest elevation of the four hand mined workings where due to the contour of the land the exposed high grade breccia material was peeled from the upslope footwall cliff face contact at all four trenches. The exposed footwall zone shows hematitic fractures and minor quartz stockwork development in argillic-hematitic altered rhyolite crystal-ash tuff adjacent to the mined out one to two meters wide breccia zone. The poorly exposed downslope hanging wall shows argillic and sericitic alteration of the crystal-ash tuff adjacent to the breccia zone. In Trench One the only exposure of remaining in situ breccia material assayed 147.9 g/t silver, 2.38 g/t gold and 1.4% copper and 15.5% iron across 0.4 meters. The only observed continuous exposure of footwall mineralization adjacent to the breccia was chip sampled in Trench One for an into the footwall ( width) upslope distance of 7.9 meters from the high grade breccia contact. This continuous zone sampling averaged 61.8 g/t silver, 0.895 g/t gold and 0.17% copper over the 7.9 meters. Also in Trench One the only in situ exposure of the hanging wall available to chip sample was a 1.2 meter width of sericitic-argillic altered rhyolite assaying 29.5 g/t silver, 0.09 g/t gold and 0.8% copper. At the other 3 higher elevation trenches, cliff face footwall chip sampling of altered hematitic fractured rhyolite returned copper, gold and silver contents comparable to those sampled in intervals at Trench One over its 7.9 meter width. However at Trenches 2, 3 and 4 ,width extent sampling of footwall mineralization is limited due to the near vertical cliff face footwall contour.
The highest grade grab sample of Sierra hydrothermal breccia was collected from the Trench Two area. Its contents of 6.0% copper, 87.2 g/t silver and 2.74 g/t gold compares well with results from the seventeen breccia grab samples as reported in 2013.
The results from the recent outcrop sampling along the mapped exposure of the Sierra breccia target confirm the high grades found in previously collected breccia grab samples. In addition, the new 2014 sampling of in situ hanging wall and footwall altered volcanics adjacent to the mapped breccia zone demonstrated that Sierra system mineralization contains copper, silver and gold and extends for at least 9.5 meters in width at Trench One.
A campaign of exploration along strike and to depth is warranted as the Sierra target hydrothermal breccias with diatreme characteristics and high-sulphidation system affinities make the potential at the Sierra system attractive.
