$BGADF announced that the first five diamond core drill holes of a 5000 metre, 40-hole program at its Picachos Property ("Picachos"
have intersected the San Agustín vein up to 180 metres below surface. Core from holes BRG-001 to BRG-005 has been received by SGS Labs in Durango. Assays will be made public upon completion of the analytical work.
The 3,954 hectare Picachos Gold-Silver Property is centered over the historic "Viva Zapata" National Mineral Reserve, Sinaloa, Mexico and features 46 veins including San Agustín. The San Agustín mine was the subject of underground channel sampling by a prior operator which returned an average grade of 81.22 grams per ton (g/t) gold (Au) and 73.36 g/t silver (Ag) across 1.2 m (Thunderbird Projects news release dated 18 June 1997). Values of 185 g/t Au were cut across the bottom of a production shaft (sample HBM-73175).
Holes BRG-004 and BRG-005 are collared below the southwestern part of a historic exploration drift accessed from the El Carrito Adit. Underground rock-chip channel sample BRG-120613 from this drift yielded an SGS lab result of 8.02 g/t gold, 63 g/t silver, 446 ppm Cu, 0.3% Pb and 0.5% Zn across 1 metre. Historic underground rock-chip channel sample MCA-29887 from extraction Level 646 contained 125.52 g/t Au and 76 g/t Ag across 1.5 metres. Drill hole BRG-004 is angled at -46 degrees towards the southeast (azimuth 112 degrees) and tested the San Agustin Vein 16 metres below MCA-29887. Anomalous silver that is expected to correlate with gold was identified using a Niton FXL benchtop XRF analyzer at several locations in the hole. The XRF silver anomaly associated with the San Agustin Vein peaks at 86 ppm Ag and occurs between 63 and 76 metres down-hole in BRG-004.
Drill hole BRG-005 is angled at -70 degrees towards the southeast (azimuth 114 degrees). It tested the San Agustin Vein 51 metres below the intercept of BRG-004. The XRF silver anomaly associated with the San Agustin Vein peaks at 68 ppm Ag and occurs between 92 and 115 metres down-hole in BRG-005. The upper part of this silver anomaly is associated with quartz-specularite veining in argillite. The lower part is located at the contact of argillite in the hanging wall, and porphyritic ignimbrite correlated to the Tarahumara Formation in the footwall. This contact is faulted and mineralized with precious metal bearing microcrystalline and crustiform quartz. Panned pulp samples from both quartz-specularite and microcrystalline quartz veinlets show gold.
