East Star Resources Plc
("East Star" or the "Company")
Verkhuba Copper Deposit Drilling Underway
First major operational milestone of Joint Venture with Xinhai
East Star Resources Plc (LSE: EST), the Kazakhstan-focused gold and copper exploration and development company, is pleased to announce the commencement of drilling at the Verkhuba Copper Deposit ("Verkhuba"), as part of its Joint Venture ("JV") with Hong Kong Xinhai Mining Services Ltd ("Xinhai").
Highlights
· A programme of approximately 5,000 metres of diamond core drilling has commenced.
· The drilling programme is intended to support resource conversion, geological modelling, mine planning and feasibility study activities, with particular focus on the first 3 to 5 years of mining operations.
· East Star is allocating two geologists and providing some additional administrative support, paid for by Xinhai through the JV, to ensure continuity of care in exploration and relationships with local stakeholders.
· Drilling is expected to take up to 3 months with assays and an updated resource to follow shortly after.
· The drilling programme is at no cost to East Star which is fully carried to production. At that point East Star will hold 30% of the producing mine with a current JORC Inferred Resource of 20.3Mt @ 1.16% copper, 1.54% zinc and 0.27% lead.
Alex Walker, CEO of East Star, commented:
"Having established the JV company and received initial funding from our partner, Xinhai, we are now moving directly into the operational phase required to advance the project towards feasibility. This circa 5,000-metre programme will provide the data required to support resource conversion and inform mine planning, bringing us closer to production of a sizeable deposit at no further cost to East Star."
