Blackstone Minerals Limited announced it has intersected high-grade massive sulfide Nickel-Cu-PGE in four maiden drill holes at Ban Chang, part of its Ta Khoa Nickel-Cu-PGE project in Vietnam, after receiving results for the latest hole, BC20-04. The four maiden drill holes were drilled more than 1.2km apart and along strike within a 1.2km-long massive sulfide target zone defined by high priority EM plates. The Company has quickly moved to an aggressive drill out phase to delineate a maiden resource at Ban Chang to supplement the ongoing studies focused on producing nickel sulfate for the lithium-ion battery industry. Blackstone's fourth maiden drill hole BC20-04 at Ban Chang is located more than 1.2km along strike from. Blackstone's first maiden drill hole BC20-01. It intersected the following high-grade results: BC20-04: 21.5m @ 0.69% Ni, 0.66% Cu, 0.03% Co & 0.81g/t PGE from 71m; 13.4m @ 1.01% Ni, 0.96% Cu, 0.05% Co & 1.14g/t PGE from 76m. Incl. 2.1m @ 2.53% Ni, 1.36% Cu, 0.11% Co & 0.76g/t PGE from 77.6m. Blackstone's previously announced maiden drill holes BC20-01, BC20-02, and BC20-03 intersected the following high-grade results: BC20-01: 5.2m @ 0.66% Ni, 0.73% Cu, 0.04% Co & 0.79g/t PGE from 58.0m; 1.5m @ 2.20% Ni, 2.12% Cu, 0.13% Co & 2.66g/t PGE from 58.5m. Incl. 1.05m @ 2.98% Ni, 1.22% Cu, 0.18% Co & 3.43g/t PGE from 58.5m. BC20-02: 4.1m @ 0.92% Ni, 0.69% Cu, 0.05% Co & 0.26g/t PGE from 85.9m; 2.3m @ 1.6% Ni, 1.09% Cu, 0.09% Co & 0.43g/t PGE from 85.9m. Incl. 1.8m @ 2.01% Ni, 1.27% Cu, 0.12% Co & 0.53g/t PGE from 86.4m. BC20-03: 9.8m @ 1.45% Ni, 0.9% Cu, 0.08% Co & 0.70g/t PGE from 57.05m; 5.7m @ 2.07% Ni, 1.08% Cu, 0.12% Co & 0.95g/t PGE from 60.0m. Incl. 1.85m @ 3.59% Ni, 1.18% Cu, 0.20% Co & 1.97g/t PGE from 63.35m. The Ban Chang prospect is located 2.5km south-east of the Ban Phuc deposit and processing facility, adjacent to the Chim Van ­ Co Muong fault system. The prospect geology consists of a tremolitic dyke swarm within phyllites, sericite schists and quartzites of the Devonian Ban Cai Formation. The known mineralization style is mainly veins and lenses of massive sulfide as well as disseminated sulfide (DSS) hosted within tremolite dykes. The dyke swarm is approximately 900m long and varies between 5m and 60m wide. The dykes and massive sulfide are interpreted to be hosted within a splay off the major regional Chim Van ­ Co Muong fault system. The West Zone is a 420m long zone of interpreted bifurcating MSV lenses. This zone strikes NW-SE and dips moderately to the SW. The Central Zone is consistent in strike and dip with the West Zone, defined by a weathered gossan which is 200m long and up to 1.4m wide and containing 0.18- 0.27% Ni and 1.29- 1.38% Cu. The prospect area was historically mapped and trench sampled (19 trenches) by Vietnamese geologists in the 1960-63 period. The largest intersection obtained in this period was in Adit Level 13 which intersected patchy zones of weak nickel-copper mineralisation. Channel samples included 3.9m at 1.07% Ni & 0.95% Cu including 1.1m at 1.62% Ni & 1.48% Cu. Drill hole BLK 4 intersected a zone of 1.7m at 1.89% Ni & 0.91% Cu from 62.9m. Drill hole BLK 2 intersected a 1m wide MSV within schist grading 2.65% Ni & 1.07% Cu from 58.5m down hole. Blackstone Minerals aims to deliver a maiden resource in third quarter, focused initially on the DSS at Ban Phuc and continues to investigate the potential to restart the existing Ban Phuc concentrator through focused exploration on both MSV and DSS deposits. Blackstone Minerals has commenced a scoping study on the downstream processing facility at Ta Khoa. The scoping study, also to be announced in third quarter, will provide details for joint venture partners to formalise the next stage of investment. Blackstone Minerals has commenced metallurgical testing on the Ban Phuc DSS deposit with an aim to develop a flow sheet for a product suitable for the lithium-ion battery industry. In addition, Blackstone Minerals will investigate the potential to develop downstream processing infrastructure in Vietnam to produce a downstream nickel and cobalt product to supply Asia's growing lithium-ion battery industry. The Ta Khoa Nickel-Copper-PGE Project in northern Vietnam includes an existing modern nickel mine which has been under care and maintenance since 2016 due to falling nickel prices. Existing infrastructure includes an internationally designed 450ktpa processing plant. Previous project owners focused mining and exploration efforts primarily on the MSV at Ban Phuc.
