Alamos Gold, Orla Mining and Oroco Resource released drilling results during the first week of February. Alamos Gold presented high grade gold results on epithermal high sulfidation mineralization from the Puerto del Aire zone of the Mulatos project in Sonora. Puerto del Aire is a higher-grade underground deposit, adjacent to the main Mulatos pit, holding 428,000 Oz Au in mineral reserves grading 4.67 gpt Au. Since that resource estimation, further 27,117 m in 92 holes have been drilled. The interval of 25.95 m grading 33.40 gpt Au is one of the highest reported since this compilation began last year.
Orla Mining results on drilling of the sulfide zone of the Camino Rojo deposit in Zacatecas produced also very good high gold grades over tens of meters of core length in tentative feeder zones to the Camino Rojo intermediate sulfidation mineralization hosting 7.3 M Oz Au in measured and indicated resources. According to Orla, this mineralization is underlain by garnet bearing skarn mineralization, pointing to a distal gold skarn model for the overall system. Regional exploration drilling produced up to 7.10 m @ 0.54 gpt Au and 2.35 m @ 1.35 gpt Au at the Guanamero target.
Oroco Resouce drill results are from the South Zone of its Santo Tomás porphyry copper project in Sinaloa. Core intervals are said to be within 10% of true width. The zone is approximately 2 km long and divided in the northern, middle and southern segments, with the 500 m long northern one still pending to be drilled. The southern segment is characterized by west dipping intrusions and mineralization, cut by hydrothermal breccia bodies and stockwork and vein mineralization.
The drill intercepts by Gatos Silver correspond to last week’s press release on drilling at Cerro Los Gatos in Chihuahua. The drilling expands the intermediate sulfidation epithermal mineralization in the South-East Deeps zone laterally and at depth since last October by 400 m in strike length and 85 m vertically.
