Minera Camargo

Exploring the Sierra Madre of Mexico for gold and base metals.


Recently completed airborne LiDAR (light detection and ranging) has mapped the exact location of more than 680 adits, prospect pits and historic mine excavations.    

Time Event
1983 The Consejo de Recursos Minerales (now the Servicio Geologico Mexicano or SGM) staked the “Viva Zapata” concession over a total surface area of 31,705 Ha on behalf of the Mexican Government. Existing claims internal to “Viva Zapata” included Nuestra Señora de La Candelaria, Los Placeres, La Norteñita, San Antoñio, San Agustín, La Chorrera, El Rodeo and La Soriana.
1984 The SGM mounted a significant exploration campaign including at least four geologists. Their mandate was to sample and document the known workings both on the “Viva Zapata” concession and on the internally held Properties. La Gloria returned values of 54 g/t Au and 20 g/t Ag across 0.1 m (AVG 2 channel samples), San Agustín 8 g/t Au and 41 g/t Ag across 1.1 m (AVG 15 channel samples), and Los Tajitos 7.6 g/t Au and 54 g/t Ag across 0.9 m (AVG 15 channel samples).
1987 The SGM sent a geologist to sample the Tatemales workings on the Nuestra Señora de la Candelaria Property. Seven underground chip-channel samples, between 0.2 and 1.02 meters wide, yielded average results of 1.82 g/t Au and 39 g/t Ag across 0.6 meters.
1990's Minas Picacho drove a 200 meter long tunnel underneath the historic San Agustín mine. In 1997, they sold the mine to Thunderbird Projects, who agreed to acquire 100% of the shares of Minas Picacho for: (i) the reimbursement of U.S. $560 000 of exploration expenses, (ii) make underlying payments to the vendors of U.S. $1 300 000, and (iii) issue 5,000,000 shares at a deemed value of $0.24 per share (Thunderbird Projects news release, 18 June 1997).
1998 Esperanza del Oro was active on the Profeta Property, a group of 3 concessions overlapping the northern half of what is now the Tango concession. They completed a preliminary prospecting, soil sampling and hand trenching program in several phases over a 3-year period.
1999 SGM completed regional geological mapping and stream sediment geochemical sampling of Cacalotán map sheet F13A47 and La Rastra map sheet F13-A48.
2003 Minera Camargo completed traverses of El Placer, La Cocolmeca and San Agustín. Eleven historic workings were located and sampled. The average result of these samples was 6.3 g/t Au, 75.2 g/t Ag, 0.9% Cu, 0.2% Pb and 0.4% Zn. The Tango concession was applied for by Minera Tango, a business owned partly by Minera Camargo and Tango Mineral Resources. RNC Gold did a reverse-takeover of Tango Mineral Resources.
2004 RNC Gold optioned the Project to Northwest Mineral Ventures. Soil sample geochemistry and underground mine chip-channel sampling was completed. The best underground result was 21.09 g/t gold and 6 g/t silver across 0.8 meters from La Gloria. The average result of 502 soil samples was 197 ppb gold, 0.9 ppm silver, 115 ppm copper, 321 ppm lead, and 599 ppm zinc.
2005 Northwest Mineral Ventures acquired the Tango 2 concession based on identification of a strong copper anomaly in the SGM stream sediment sample database then dropped their option.
2006 RNC Gold did a stream sediment survey of the Property. The best result was 6841 ppb gold from a creek downstream of San Antoñio. Yamana Gold merged with RNC Gold. Seafield Resources purchased Minera Tango from Yamana.
2007 Seafield Resources completed surface trenching of La Cocolmeca Vein and extended the soil geochemical grid. The best result was 44.09 g/t Au, 47 g/t Ag, 0.4% Cu, 0.2% Pb and 0.7% Zn across 0.8 m from Mina San Antoñio.
2008 Seafield Resources completed 1747 meters of reverse circulation drilling in 14 holes. The best result was 2.04 meters of 80 g/t Ag, 5.0% Pb, 0.74% Zn and 1.0% Cu between 89.76 and 91.8 meters in Hole TAN10. A rock-sample grid of 100 m by 100 m was completed on the porphyry.
2009 Minera Camargo bought the Property from Seafield Resources.
2012 Hudbay Minerals completed a widely spaced soil survey of the porphyry prospect.
2013 Minerales Vane S.A. de C.V. took about 1300 tonnes of gold bearing rock from a natural block cave at the north end of the 619 m level extraction level of the San Agustín Vein in the first half of 2013 to their processing plant at San Dieguito de Arriba (SDA) in Acaponeta, Nayarit. An electronic report provided by the metallurgist stated that the dry weight of the material was 1100 tonnes with a head grade of 6.25 g/t Au. They recovered 5221 g of gold and 13600 g of silver.
2014 Minerales Vane withdrew another 1500 tonnes of rock from the same place and sent it to the SDA mill. The metallurgist reported that 1502.7 tonnes were milled, 8.56 tonnes of concentrate were produced (using sulfide flotation), and 162.44 tonnes of gambusino tailings were moved from the mine to the SDA mill. Vane reported a head grade of 4.35 g/t Au and 47 g/t Ag for all material, a concentrate grade of 577 g/t Au and 1171 g/t Ag and a tailings grade of 0.78 g/t Au and 24 g/t Ag. Rose Petroleum, the owner of Minerales Vane, optioned the Property until the end of 2016.
2017 to 2019 Minera Camargo sampled San Agustín, El Pino, Los Lentes, Urrea, El Salvador, Colorín, La Víbora and La Tarántula Veins from underground. The best result was 113.08 g/t gold and 62.2 g/t silver across 1 meter from San Agustín.
2020 to 2021 Brigadier Gold Ltd. optioned the Property and completed 5057 meters of diamond drilling, 5343 meters of surface trenching with underground sampling and a LiDAR topographic survey. Brigadier drilled 7.45 g/t Au, 51 g/t Ag, 321 ppm Cu, 0.19% Pb and 0.34% Zn across a 7 m core width at San Agustín and 12.62 g/t Au, 78 g/t Ag, 4.51% Cu, 0.16% Pb, 0.23% Zn across 0.8 meters core width at San Antoñio.
