Assays From Drilling At The Highland Gold-Silver Property
VANCOUVER - Bravada Gold Corporation reported that seven holes (a total of 2,098.4 meters) were drilled in two areas, with further analysis planned.
President, Joe Kizis, said, "Highland is a large property with multiple "hot spots" of high-grade gold at surface in the upper portion of a large low-sulfidation-type gold/silver system where undiscovered high-grade vein deposits may be preserved in their entirety. A recent example is Hecla's discovery in December 2020 of the Green Racer deposit beneath barren sinter on their Midas property, a Nevada mining operation placed in production 23 years ago."
All four holes in the Western Vein zone returned 1.5 to 9.1 meter intercepts of +0.3 grams per tonne (g/t) gold and anomalous silver within wider zones of anomalous gold values. Bravada has arranged for several of the vein zones to be re-assayed for gold and silver by preparing a new, 500-gram pulp from rejects to evaluate the possibility of particulate gold issues in the vein zones, which has previously been observed on the property.
Vein mineralogy and textures along with very low concentrations of base metals suggest the intercepts are from shallow levels of the hydrothermal system, likely above any extensive zones of high-grade gold. Hole HL21-2 is north of a post-mineral fault that has down-dropped and offset the main vein zone to the west and may have intersected that zone in the 7.6m interval of 0.425g/t Au and 45.0g/t Ag. A 2006 drill hole, HL-8, is located approximately 400m to the NW along projected strike and may be the further extension of the main vein zone. HL-8 (previously reported) intersected several vein zones including 1.5m of 1.8g/t Au and 74g/t Ag and 7.6m of 0.4g/t Au and 17g/t Ag. Only two other shallow holes have been drilled in this overburden-covered area and both intersected similar gold values in similar shallow-level quartz/carbonate vein material.
Three holes were drilled in the eastern portion of the property, one on the Big Hammer target (HL21-07) and two farther east (HL21-05 & HL21-06) that tested faults identified by CSAMT geophysics beneath extensive sinter and overburden. Low concentrations of anomalous gold and arsenic were encountered at shallow depths in the two eastern-most holes, but concentrations returned to background levels above the targeted fault intersections. The hole at Big Hammer did intersect a narrow zone of +0.3g/t gold and widespread anomalous arsenic, but very little quartz veining. The data will be reviewed in greater detail, but it is consistent with extensive lateral flow in this shallow level of the hydrothermal system.
Recent mapping and new gravity geophysics has not yet been evaluated in detail; however, detailed mapping at the Geyser Target has refined the presence of a well-preserved paleo-geyser conduit and surrounding near-vent facies of sinter at the intersection of a NW-trending graben/fault zone and the southern E-W trending Desotoya Caldera margin. The poorly exposed, NW-trending Cabin vein system was also refined, with additional sampling confirming strongly anomalous, multi-gram gold values.
