Blackstone Minerals Limited announced that mining activities have recommenced at the Company's 90% owned Ta Khoa Nickel Project in northern Vietnam. Using a combination of Australian and Vietnamese mining professionals and operators, Blackstone will: Complete ~1,000m of development through the Ban Phuc disseminated orebody generating nickel ore representative of the life of mine plant feed. Recommission the Ban Phuc Nickel Concentrator to produce two batches of Nickel Concentrate for use in the Ta Khao Refinery piloting programs. Deliver the first batch of concentrate to Perth for treatment by ALS Laboratories in the first phase piloting program. Process and store the second batch for use in the second phase pilot plant which will be built in Son La in 2022. In December 2021, Blackstone was granted approval to recommence mining activities as part of its ongoing development of the Ta Khao Project. Approval was received to perform mining works that will involve completion of ~1,000m of lateral development. The development drive starts from the 1,270mRL level of existing Ban Phuc underground workings (approximately 130m below natural ground level) and extends completely through the middle of the Ban Phuc disseminated sulfide resource. Multiple cross cuts extend from the main development drive to provide access to a wide distribution of ore zones. Ore produced from the mining program will be processed through the existing 450ktpa Ban Phuc concentrator. Blackstone has finalised studies to temporarily de-rate the existing plants capacity to suit the requirements of the pilot programs. Blackstone has refurbished the Ban Phuc concentrator over the last six months. The crushing circuit was recommissioned in November 2021, with ore commissioning planned for the mill and flotation circuit in January 2022. The first parcel of ore will be treated in a semi-batch manner. Approximately 10 tonnes (t's) of 8% nickel concentrate will be shipped to ALS in Perth for use in the phase 1 piloting program. Following this first campaign, several larger campaigns will be used to test the milling and flotation performance of the Ban Phuc disseminated sulfide, and generate nickel concentrate for further large-scale piloting use. This concentrate will be bagged and stored in containers for treatment through the Phase 2 Pilot Plaint in Vietnam. Blackstone has also purchased an upstream pilot plant capable of treating 250kg/hr. During the main campaigns, Blackstone will also run multiple trials through this pilot facility to optimise flotation parameters for the DFS, as well as testing pilot versions of key process equipment.
