Underground Sampling from Undrilled Surrounding Veins Returns 109.14 g/t Gold and 20 g/t Silver Across 0.5 Metres
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:
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.

San Antoñio is a historic prospect cut across the major ENE trending Cocolmeca Vein system that bisects the Property along the 8 km ENE diagonal 250 metres northwest of La Gloria Gold Mine. Values of 44.1 g/t Au, 47 g/t Ag, 0.4% Cu, 0.2% Pb and 0.7% Zn across 0.8 metres were obtained in historic sample MTA-19856. A prior operator drilled RC hole TAN3 under MTA-19856 in 2008 and got a result of 0.8% Cu, 0.29 g/t Au, 451 ppm Pb and 525 ppm Zn across 1.02 metres between 84.66 metres and 85.68 metres down-hole. Brigadier decided that historic result did not make sense considering the high-grade nature of this large, continuous vein. To clarify this view, two PQ diamond core holes were drilled with pierce points into La Coco on either side of TAN3. DH-BRG-026, cut northeast of TAN3, yielded a result of 1.07 g/t Au, 18 g/t Ag, 0.4% Cu, 0.2% Zn across 3.9 metres between 74 and 77.9 metres. This result includes 4.44 g/t Au, 6 g/t Ag, 0.1% Cu across 0.9 metres between 77 and 77.9 metres. DH-BRG-027, cut southwest of TAN3, intercepted a vein of semi-massive chalcopyrite with 12.62 g/t Au, 78 g/t Ag, 4.5% Cu, 0.2% Zn, 0.2% Pb across 0.8 metres between 54.7 and 55.5 metres down-hole. Both intercepts have significant hangingwall and footwall alteration comprised of piemontite, sphalerite, galena, pyrite and chalcopyrite (similar to La Gloria). From this data Brigadier concludes that the RC drilling method used previously was inadequate for sampling the Veins on this Property, although it was successful in locating the Veins in the subsurface.

Nearby NW trending Veins
Several underground mines and prospects are developed on near-parallel veins within 500 metres to the southwest of La Gloria. These include Colorín, El Salvador, Urrea and Mangos. Of these, Urrea is the best developed with extraction levels at 840 metre, 860 metre, 895 metre, 935 metre and 1040 metre. Underground rock chip-channel results from these Veins include:
The Company has located and mapped several underground drifts and cross-cuts northwest of Lentes (Company PR dated 6 October) and near the Cobre Veins. A new batch of 224 underground and trench samples has been received by SGS laboratories. Results will be published when these are available from the Lab.

The Picachos land package was methodically assembled by Michelle Robinson (MASc., P.Eng., Geologist and Qualified Person) over 10 years ago. Michelle is a respected industry veteran who has worked in Mexico for over 20-years with a number of major mining companies. She has authored over 20 technical reports and published several papers for the Society of Economic Geologists. Michelle and her team are executing on our 5,000-metre diamond drill program – the first ever on this project
The project’s location, situated 25 kilometres equidistant from two recent bonanza grade discoveries of Vizsla Resources and GR Silver and along the same mineralized trend, positions Picachos as a truly exciting opportunity for Brigadier Gold and our shareholders.
The 3,954 hectare Picachos Property is centered over the historic “Viva Zapata” National Mineral Reserve, Sinaloa, Mexico. It overlaps two mineralized systems, a porphyry copper-molybdenum system hosted by a Paleocene granite-granodiorite intrusive complex, and a gold-silver vein complex comprised of both east-northeasterly trending veins (La Cocolmeca Vein System) and northwesterly trending veins (El Placer System). Sericitic alteration related to the porphyry system has been mapped over the northwestern two-thirds of the Property. Quartz-biotite veinlets with chalcopyrite and bornite occur in the central part of this broad zone of sericitic alteration and imply the presence of a significant porphyry system at depth. La Colcomeca Vein system has been mapped from San Agustín Underground Gold Mine in the southwestern part of the Property to El Pino seven kilometres to the northeast. In the central part of the Property, the best exposure of the northwesterly trending system occurs between La Gloria Underground Gold Mine and the Urrea Gold Mines, located 630 metres southwest of La Gloria. In this area, other northwesterly trending veins between these veins include Paldodismo, Colorin, Salvador, Trompetas and Mangos. On the eastern part of the Property, Tatemales and La Botica define a four kilometre long trend.
The growing inventory of priority drill targets underscore the untapped potential of this particular region of Sierra Madre Occidental epithermal belt.
