Vancouver, British Columbia – February 17, 2021 – Brigadier Gold Limited (the “Company” or “Brigadier”) (TSXV: BRG|FSE: B7LM|USA: BGADF) is pleased to provide additional diamond drill and underground sampling results from ongoing phase one exploration at its Picachos gold-silver project, Sinaloa Mexico (the “Picachos Project”, “Picachos” or the “Property”). Brigadier has completed and received assay results for 3085 metres of diamond drilling in 28 holes on the Picachos Project. Assays results for holes 21 through 28 and recent underground sampling are provided in Table 1.
Phase-one exploration highlights to date:
- Confirmed seven-kilometre long vein system of precious metals mineralization
- Widely spaced holes show vein continuity on strike and at depth with robust width
- High grade nature of precious metals mineralization consistently observed in assays
- Confirmed meaningful gold/silver mineralization in hanging wall and footwall of vein systems
- Discovered previously unexplored high-grade gold and silver historic workings
- Multiple new surface and subsurface targets discovered during reconnaissance and mapping
- Copper porphyry target sampling suggests high priority follow-up exploration
Geologist and Qualified Person as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), Michelle Robinson comments “results of our phase-one program at Picachos imply a robust and geographically expansive mineralized system for which we have only just scratched the surface. I am very pleased with our results, in particular the number of targets demanding follow up drilling or for newly discovered zones, a first ever drill hole. The Cocolmeca vein structure (CVS) is persistent and strongly mineralized and I look forward to expanding the depth and strike length in 2021, as well as continuing the exploration of the rest of the CVS, particularly in the central Cocolmeca area.”
Of the 28 holes drilled to date, fourteen (1704 metres) were drilled to test the San Agustín Vein, 10 holes (1029 metres) tested surface exploration targets defined by trenching, 2 holes (168 metres) tested under the historic San Antoñio Mine and one hole tested under the historic La Gloria Mine. San Agustín and San Antoñio represent two gold-rich, polymetallic mineral chutes about 2.5 kilometres apart on Brigadier’s regional-scale Cocolmeca Vein System (CVS), and La Gloria historically produced gold from a northwesterly trending vein roughly orthogonal to the CVS. The CVS has been defined at varying levels of certainty along the east-northeasterly trending diagonal of the Property for more than seven kilometres.
La Gloria Gold Mine and Palodismo
La Gloria underground gold mine is accessed from a 106 metre long east-southeasterly trending cross-cut located at 965 metres elevation in the central part of the Property. This opening provides access to a southeasterly trending stope that is more than 70 metres long and about 1.5 metres wide. Historic sample MTA-15659 was cut across the northwest face of this stope and contained values of 21.09 g/t Au, 6.6 g/t Ag, 0.4% Cu, 0.8% Pb and 0.5% Zn across 0.8 metres. The orientation of the structure at this location is 162°/75° SW. Brigadier cut a sample across the southeastern face of the stope which returned a result of 49.6 g/t Au and 31 g/t Ag across 0.4 metres (BRG-26402) and a notably more easterly orientation of 150°/74° SW. Mineralization in the stope consists of microcrystalline quartz breccia intergrown with pink epidote (piemontite?), and native gold along a shear zone hosted in agglomerate. The mud matrix between volcanic blocks and bombs is pervasively replaced by microcrystalline grey quartz intergrown with galena, sphalerite and lesser chalcopyrite.
Palodismo was first identified in historic sample MTA-19690 with results of 27.61 g/t Au and 4 g/t Ag across 1.3 metres from a small underground prospect 65 metres north of the entrance to La Gloria. Characteristic “pink epidote-quartz” is mentioned in the notes from 2007. A second underground prospect 115 metres SE of La Gloria cross-cut was sampled by Brigadier with results of 9.7 g/t Au and 2 g/t Ag across 0.8 metres (BRG-25207). Measured vein orientations from both prospects are 147°/75° SW.
Drill hole BRG-028 was collared 72 metres southwest of La Gloria. It was designed to intercept both Palodismo and La Gloria under historic sample MTA-15657 with a result of 5.27 g/t Au and 7 g/t Ag across 1.5 metres. All of DH-BRG-028 was altered to propylitic mineral assemblages dominated by epidote and chlorite. Microcrystalline galena and sphalerite in silicified mud between volcanic blocks and bombs defines a broad geochemical response of 0.4% Zn, 0.2% Pb, 170 ppm Cu, 0.2 g/t Au and 2 g/t Ag along the entire hole length of 183.5 metres. The section between 59 and 64 metres contains 1.2% Zn and 0.3% Pb with 348 ppm Cu across 5 metres. Shear zones marked by kaolinite and/or and pink quartz-piemontite breccias contain elevated gold values. Several of these were intercepted in the hanging wall to Palodismo. One of these contains 1.8 g/t Au and 1.9 g/t Ag across 2 metres between 35 and 37 metres. Palodismo itself is defined by a geochemical anomaly of 2.29 g/t Au across 8 metres between 105 and 113 metres. The Palodismo Vein is marked by pink quartz-epidote breccia between 110 and 111 metres with values of 10.65 g/t Au across 1 metre. A three-point solution between MTA-19690, BRG-25207 and this intercept in DH-BRG-028 yields an orientation of 145°/73° SW, in good agreement with field measurements from underground exposures of Palodismo.
A second intercept of 6.26 g/t Au between 141 and 142 metres in DH-BRG-028 is only tentatively correlated to La Gloria Vein. This interpretation implies that the vein flattens out at depth to a dip of about 65 degrees. Alternatively, the strike may have changed as implied by BRG-26402, and DH-BRG-028 never reached La Gloria Vein. Further drilling is required to clearly define La Gloria Vein at depth.
