High-Grade Gold Intersections At North Hill And Silicia Ridge

VANCOUVER - Gold Bull Resources Corp.reported on the 2022 Drill Program with all gold assays received from its Sandman Project, located in Humboldt County, Nevada. The reverse circulation (RC) drilling program comprised 24 holes for 4,954m (16,253ft). High grade gold intersections were drilled at North Hill and Silica Ridge. Gold intersections extended beyond the Abel Knoll resource by 100 m to the east, and it remains open at depth and along strike. Scout drill holes in the Sandbowl target west of North Hill and at a new exploration target north of Abel Knoll intersected significant zones of anomalous gold, worthy of follow-up.

CEO, Cherie Leeden, said, “The drill results yielded widespread gold intersections, including high grade at North Hill, Silica Ridge and Abel Knoll, with the best gold intersection received from Silica Ridge SA-0052 returning 83.8 m @ 1.50 g/t Au from the surface, including a significant intersection of 3m @ 14.67g/t gold and 1.5m @ 15.53g/t gold as well as hole SA-0037 from North Hill returning 32m @ 1.31g/t Au from 42.7m including 1.5m @ 9.34g/t gold at North Hill. The intersections of low-grade gold mineralization over significant widths at Sandbowl and north of Abel Knoll open new areas for further exploration. A scoping study investigating the economic parameters of a near-term production scenario is well underway.

The Sandman 2022 drill program comprised 24 reverse circulation drill holes for 4,954m (16,253 feet). All assays have now been received. The program included eight (8) holes targeting deeper mineralization beneath the existing mineral resources at North Hill and Silica Ridge, a further eight (8) holes were drilled around existing deposits testing for extensions to the currently defined Mineral Resource Estimate (MRE). Eight (8) scout holes were drilled testing targets at Midway, Sandbowl and Windmill.

Although the scout holes did not yield a high-grade discovery, the intersection of multiple zones of low-grade strata-bound mineralization at Sandbowl may indicate the presence of a gold-bearing fluid feeder structure that has not yet been intersected by drilling. Similarly, the intersection of 13.7 m (45 ft) @ 0.42 g/t Au from 175.2 m (575 ft) in an interpreted north-south striking structure 1.7 km (1.1 mile) north of Abel Knoll defines a potentially significant new mineralized zone that is open in all directions. Further evaluation of these results is warranted to understand the potential for a higher-grade orebody close to these intersections.”

Six (6) holes were drilled at Silica Ridge, with four drill holes (SA-0043, SA-0044, SA-0045, SA-0052) targeting down-dip extensions to the Mineral Resource Estimate. The holes targeted intersections of structures projected beneath the deposit close to the basement contact, at which hydrothermal mineralizing fluids flow from the tighter Triassic phyllite basement rocks into the more porous Tertiary units above. The holes intersected silicified tuff and quartz-adularia altered, iron oxide-stained sandstone, conglomerate, and tuff.

The best results intersected at Silica Ridge were received from holes SA-0044, SA-0045 and SA-0052. Hole SA-0044 returned 47.2m (155 ft) @ 1.54 g/t Au from 1.5m (5 ft), including 6.1m (20 ft) @ 8.01 g/t Au from 3m (10 ft), as well as 1.5m (5 ft) @ 13.87 g/t from 3m (10 ft) and 1.5m (5 ft) @ 1.15 g/t from 24.4m (80 ft). Hole SA-0045 intersected 74.7m (245 ft) @ 0.93g/t Au from 0m (0ft), including 3m (10ft) @ 1.55g/t Au from 0m (0 ft) and including 51.8m (170 ft) @ 1.12 g/t Au from 22.9m (75 ft), as well as 3m (10 ft) @ 2.28 g/t Au from 25.9m (85 ft) and 18.3m (60 ft) @ 1.98 g/t Au from 38.1m (125 ft), and a high grade intersection of 1.5m (5 ft) @ 13.13 g/t Au from 41.1m (135 ft) and 7.6m (15 ft) @ 1.29 g/t Au from 65.5m (215m). Gold mineralization with grades >0.1g/t extends intermittently to a down-hole depth of 195m (635 ft) in hole SA-0052.

Hole SA-0043 intersected an upper 25.9 m wide zone of low-grade zone containing strata-bound mineralization to the west of the current Mineral Resource Estimate, returning 1.5 m (5 ft) @ 0.25 g/t Au from 27.4 m (90 ft), 3.0 m (10 ft) @ 0.51 g/t Au from 36.6 m (120 ft), and 9.1 m (30 ft) @ 0.47 g/t Au from 44.2 m (145 ft). This result indicates that shallow incremental gold ounces could be added to an open pit resource by extension drilling to the west of Silica Ridge.

The highest-grade mineralization within the Silica Ridge Mineral Resource Estimate occurs at the intersection of structures striking north-northwest to south-southwest and east-west, intruded by a mafic dike. Drillhole SA-0046 was collared east of Silica Ridge to test the intersection of the E-W dyke with a NNW striking dyke associated with an extensive lag geochemical anomaly. However, the hole failed to test the targeted structure due to early abandonment caused the hole collar blowing out.

Five (5) drill holes were drilled at North Hill with four (4) holes (SA-0035, SA-0036, SA-0037 and SA-0038) targeting modeled feeder structures below the Mineral Resource Estimate. The fifth hole (SA-0039) was drilled east of the Mineral Resource, testing a down dip extension to strata-bound mineralization. The intersection of 4.6 m (15 ft) at 0.94 g/t Au from 39.6 m (130 ft) in SA-0039 extended the known deposit laterally by 80m.

The drill holes targeted intersecting gold bearing structures below the North Hill deposit and high-grade gold was intersected in the upper portions of the holes, with intermittent lower grade (>0.1 g/t) gold intersected in the deeper portions of the drill holes. Results from SA-0035 returned more consistent gold at depth above the basement phyllite contact, indicating the hole is possibly close to a gold bearing structure. Further evaluation of this hole and potential feeder structures is required.

The best North Hill intersections include holes SA-0035 returning 7.6 m (25 ft) @ 1.51 g/t Au from 48.8 m (160 ft), and SA-0036 returning 19.8m (65 ft) @ 0.71 g/t Au from 33.5m (110 ft) including 9.1m (30 ft) @ 0.84 g/t Au from 33.5m (110) ft and including 1.5m (5 ft) @ 2.91 g/t from 36.6m (125 ft). Hole SA-0037 returned 32m (105ft) @ 1.31 g/t Au from 42.7m (140 ft), including 19.8m (65 ft) @ 1.56 g/t Au from 42.7m (140 ft) and 1.5m (5 ft) @ 9.34 g/t Au from 59.4m (195 ft). Hole SA-0038 returned 7.6m (25ft) @ 2.35 g/t Au from 83.8m (275m), including 1.5m (5 ft) @ 9.3 g/t Au from 88.4m (290 ft).

Six (6) holes were drilled at Abel Knoll targeting deposit step-out holes with five (5) drilled to the east of the prior 2021 Mineral Resource Estimate (MRE) boundary and one (1) drilled north of the western mineralized diatreme breccia. Step out drilling east of the Abel Knoll MRE intersected low-grade (0.2 to 0.4 g/t Au) mineralization in holes SA-0048, SA-0049, SA-0050, SA-0051, and SA-0056. Significant mineralized intervals were intersected in SA-0048 and SA-0049. SA-0048 returned intersections including 42.7 m (140 ft) at 0.35 g/t Au from 74.7 m (245 ft) and 18.3 m (60 ft) @ 0.26 g/t Au from 135.6 m (445 ft). SA-0049 returned a best intersection of 56.4 m (185 ft) @ 0.2 g/t from 103.6 m (340 ft). These intersections are located east of the previously reported intersection of 90 m (295 ft) at 0.6 g/t Au from 76.2 m in SA-0031.

Eight (8) exploration scout holes were drilled to test targets at Sandbowl (SA-0053 and SA-0054), Midway (SA-0040 and SA-0041), east of the Silica Ridge deposit (SA-0046), Windmill (SA-0055), west of North Hill (SA-0034) and north of Abel Knoll (SA-0057). Gold mineralization was intersected in the Sandbowl holes, with SA-0053 and SA-0054 returning low grade but anomalous gold in a fluviatile Tertiary sequence. Hole SA-0053 intersected 1.5 m @ 0.46 g/t Au from 13.7 m (45 ft) and 7.6 m @ 0.24 g/t Au from 102.1 m (335 ft), and SA-0054 intersected 13.7 m @ 0.22 g/t Au from 97.5 m (320 ft) and 3.0 m @ 0.82 g/t Au from 149.4 m (490 ft). These results are very encouraging, as the holes are not located close to a deposit (400m west of North Hill deposit) and are potentially near a feeder structure for mineralizing fluids that has not yet been drilled. Hole SA-0057 north of Abel Knoll returned 13.7m (45 ft) @ 0.42g/t Au from 175.2m (575 ft) along a north-south striking fault, which is interpreted to be part of the eastern basin-bounding structural zone associated with the Abel Knoll and SE Pediment deposits. The results for this hole are encouraging, as the intersection is close to historic mineralization on competitor tenure and remains open in all directions.
