Mexico junior miner Brigadier Gold (TSSXV:BRG/FSE:B7LM) announced today that it had discovered and was sampling no less than 29 historic mine workings at its Picachos Project in Mexico.
A systematic sampling process is underway at the gold-silver project, which is located in Mexico’s rich Sinaloa mining district. Brigadier has several assays still under scrutiny at the time of writing. It is using the underground workings for previous activity at the site to get a better handle on the gold and silver deposits in the area.
Brigadier Gold has rehabilitated, mapped and sampled 29 newly discovered historic mine workings in the central part of the property near the intersection of the ENE trending Cocolmeca Vein system (CVS) and northwesterly trending El Placer system. The underground workings are concentrated in two areas named El Cobre and El Placer Norte.
Accessing and sampling these underground workings was regarded by the miner as an efficient and inexpensive way to improve Brigadier’s knowledge of the mineralising systems at Picachos. The pending assay results together with related surface trenching and nearby diamond drilling will assist in understanding the mineralization on the property and greatly assist in identifying our next drill targets.
“There is a lot of geological action in the Cobre Area”, commented Geologist and Qualified Person, Michelle Robinson. “We have northerly trending veins represented by El Cobre, Las Calzadas and 27047. These appear cross-cut and offset by the northwesterly trending El Herrero Vein. More recent strike-slip movement on La Cocolmeca is regionally important and apparently offsets some vein segments…For now, we are exploring the vein potential, but this Project has an exposed porphyry system in the northwest, and buried parts may be discovered by drilling under veins such as El Cobre”.
Results from El Cobre indicate silver, gold, lead and bismuth
At El Cobre, five principle veins have been identified. Brigadier Gold has assay results for Level 755, a crosscut 10.1 metres long oriented 070° NE across El Herrero Vein. The first 8 metres intercepted 0.12% copper in a quartz-chalcopyrite-pyrite stockwork hosted in pervasively silicified ignimbrite. The last 2.1 metres intercepted 3.3% copper and 0.56% lead with 108 g/t silver, 0.1 g/t gold, 177 ppm bismuth and 23 ppm tungsten. Most of the assays for El Cobre are pending.
Brigadier Gold said that at the El Placer Norte area individual veins were defined by mapping and sampling historic workings between 1000 and 1180 metres elevation. The historic workings are mainly short adits that follow narrow higher-grade intervals within the larger El Placer Vein system.
Underground work comes close to bonanza gold
The best result from the underground work was 31.4 g/t Au, 11 g/t Ag, 0.2% Cu, 0.5% Pb and 2% Zn across 0.3 m in sample BRG-25139.
To better understand the potential of the larger system Brigadier Gold did 80 metres of trenching across El Placer in three segments starting northeast of Los Lentes. Results include 8 metres of 2.14 g/t gold and 0.12% lead across the Tacuachas Vein (BRG-117146) and 4 metres of 1.95 g/t gold, 0.1% lead and 0.3% zinc across the surface of Los Lentes (BRG-117154).
In addition to verifying the structures mapped underground, the surface trenches have identified gold anomalies between known veins that indicate the presence of several additional veins. Assays for La Chivera, El Huarache and Pantufla are pending, the miner said yesterday.
