McEwen Mining Inc. (TSX:MUX,NYSE:MUX) announced drill results that it believes will extend the mine life and improve the grade at its Mexico-based El Gallo 1 mine. The results are from the San Jose del Alamo and Twin Domes deposits, which are the most advanced being explored.
In terms of San Jose del Alamo, the company said:
The San José del Alamo deposit is located 15 kilometres north of the El Gallo 1 mine (Figure 2). The deposit outcrops at surface and the mineralization extends to a depth of 190 metres and has a strike length of 800 metres with an average width of five metres.
A small resource estimate was released in August 2013 for San José del Alamo that was based on 36 holes. Since then an additional 73 holes have been drilled. An updated resource estimate for San José del Alamo is scheduled for Q3 2015 as part of the El Gallo 1 resource estimate update.
Metallurgical testing indicates the mineralization is amenable to heap leaching and can be processed at the El Gallo 1 mine.
Twin Domes is located 17 kilometres northwest of the El Gallo 1 mine (Figure 3). The deposit occurs at surface and extends to 40 metres depth. The current known strike length is 180 metres however a recent step out hole (TDX-053) indicates the potential to extend mineralization 200 metres to the south. Surface geochemistry also suggests the potential for mineralization further to the north.
Mineralization occurs as a series of stacked lenses with an overall width of 30 metres and individual lenses one to five metres in width. It is structurally controlled with sporadic high grades (up to 114 gpt Au). A total of 65 holes have been drilled since the deposit was discovered in 2013. Results for the first 18 holes were announced in 2013. In 2014 and 2015, 47 holes have been drilled at Twin Domes; highlights from this drilling are in Table 2. A follow-up drill program is currently in progress to both infill the deposit for resource estimation purposes as well as possibly expand the known mineralization.
An initial resource estimate for Twin Domes will be included in the El Gallo 1 resource estimate update scheduled for Q3 2015.
