Rob McEwen delivers new explorations results from his new Twin Domes discovery in Mexico.

"9.7 gpt Gold over 10.3 Meters - 17 Meters below Surface
5.0 gpt Gold over 16.8 Meters - 7 Meters below Surface
Twin Domes is located 17 kilometers (10.5 miles) northwest of the Company's El Gallo 1 heap leach mine (Fig. 1). Initial test results show that the gold mineralization at Twin Domes is potentially amenable to heap leaching, which would allow it to be processed at El Gallo 1. Ten additional core holes were completed in this recent drilling. Although it is early, McEwen Mining is highly encouraged by these results and believes Twin Domes could have a positive impact on the El Gallo 1 mine."

Higher Silver and Gold prices will provide future catalyst for this developing story and these encouraging exploration results show the basis to grow the resources for McEwen Mining in Mexico and potentially process it at the existing facilities at El Galo 1 after the ongoing expansion.


Rob McEwen: Gold prices are going up in September MUX, TNR.v, GLD

"Rob McEwen is bullish on Gold and his call about the bottom in the gold market has proven to be right so far. Silver action is particularly important for McEwen Mining now as it provides the very high leverage to its operations.

Suddenly after all doom and gloom this story is looking very promising again and Shorts has to run to cover. Los Azules copper project can change it overnight for McEwen Mining and TNR Gold.

Copper was building the base with the news from China about better economic data and high premiums in the copper supply chain due to the delivery delays. Positive news from Argentina will bring upcoming new PEA on Los Azules to the headlines again this Fall."

TORONTO, ONTARIO--(Marketwired - Aug. 19, 2013) - McEwen Mining Inc. (NYSE:MUX)(TSX:MUX) is pleased to announce core drill results from its new Twin Domes discovery, including9.7 gpt gold over 10.3 meters and 5.0 gpt gold over 16.8 meters. These results are a follow-up to the discovery holes announced in April, which intersected 8.8 gpt gold over 9.7 meters and 9.8 gpt gold over 4.6 meters, in addition to a trench that returned 20.9 gpt gold over 12.7 meters. The Company believes Twin Domes is attractive due to its higher gold grades and its close proximity to the Company's process plant.

Twin Domes is located 17 kilometers (10.5 miles) northwest of the Company's El Gallo 1 heap leach mine (Fig. 1). Initial test results show that the gold mineralization at Twin Domes is potentially amenable to heap leaching, which would allow it to be processed at El Gallo 1. Ten additional core holes were completed in this recent drilling. Although it is early, McEwen Mining is highly encouraged by these results and believes Twin Domes could have a positive impact on theEl Gallo 1 mine. Highlights are shown below.

To date, gold mineralization at Twin Domes has been identified from surface to a depth of 45 meters. The known length (or strike) of the zone is approximately 275 meters. A total of 20 additional core holes have been planned in order to follow up on these results. This program will start next week.

Samples from the core drilling were split on-site at the Company's El Gallo 1 mine. One half of the split drill core is shipped to ALS Chemex for sample preparation and analysis by fire assay for gold and 4-acid digestion with ICP determination for silver. Samples returning greater than 10 ppm gold or 1500 ppm silver were re-analyzed using gravimetric fire assay. Standards and blanks were inserted every 20 samples. All holes were drilled with HQ bits and reduced to NTW where required. Samples were taken based on lithologic and/or mineralized intervals and vary in length. Samples were analyzed by ALS Chemex using the same methods as for drill core samples. The true width of the mineral zones has not been determined.
