Tertiary Minerals starts drilling at Target A1 silver discovery in Zambia

Tertiary Minerals has commenced its largest drilling program to date in Zambia, targeting the Target A1 silver discovery at the Mushima North project. The 4,000-metre campaign aims to support the delineation of a formal mineral resource by year-end, while also testing extensions to known mineralisation and nearby targets that could add further tonnes and ounces. The existing exploration target already stands at up to 58 million ounces of silver equivalent, with managing director Richard Belcher noting substantial scope for growth across the wider project area.

For precious metals traders, this drilling program represents a potential catalyst for Tertiary Minerals' share price and the broader silver exploration sector. Positive results could validate the scale of the deposit and attract further investment, while delays or disappointing assays may weigh on sentiment. Silver prices remain sensitive to supply-side developments, and new discoveries can influence market expectations for future production. Traders should monitor assay results and resource updates as they emerge, as these will be key drivers for the stock.

Looking ahead, the company will focus on completing the drilling campaign and releasing assay results in the coming months. Success at Target A1 could lead to an expanded resource estimate and potentially a preliminary economic assessment. Investors should also watch for updates on deeper sulphide mineralisation, which Belcher flagged as an additional upside opportunity. The Zambian mining jurisdiction adds a layer of geopolitical risk, but the country's pro-mining policies have supported exploration activity in recent years.
