Tertiary Minerals to Commence Fresh Drilling at Mushima North Project in Zambia

Strategic Insights

— 1 min read

Tertiary Minerals PLC is gearing up to begin a new round of drilling at its promising silver, copper, and zinc deposit at the Mushima North project in Zambia. The AIM-listed explorer plans to spend about 1,000 metres drilling at Target A1, which is situated 28km east of the historic Kalengwa copper-silver mine. The drilling contractor, Ox Drilling, has obtained all necessary permits and is preparing to move equipment to the site. The latest drilling effort aims to follow up on encouraging results from previous drilling, which revealed high-grade intersections, including 58 metres grading 49 grams per tonne (g/t) of silver and 0.26% copper.

Key Takeaways:

  • Tertiary Minerals will commence fresh drilling at the Mushima North project in early November, spending about 1,000 metres on new drilling at Target A1.
  • The drilling is designed to follow up on encouraging results from previous drilling, which uncovered high-grade intersections of up to 49g/t of silver and 0.26% copper.
  • The mineralised area at the project now stretches approximately 450 by 400 metres and remains open in several directions and at depth.
  • The company expects the new drilling programme to take about two weeks, finishing before the rainy season begins in December.
  • Samples will first be analysed on site using portable X-ray equipment, with selected material sent to an external lab for detailed testing.
  • The data from the new drilling could support the company's first formal mineral resource estimate within the next year.
  • The Mushima North project lies within Zambia's Iron-Oxide-Copper-Gold belt, a region known for hosting significant mineral deposits.
  • The project has already shown signs of elevated metals such as bismuth, antimony, and gallium alongside silver, copper, and zinc, indicating a diverse mineral signature.

Statistics:

  • 1,000 metres: the planned length of new drilling at Target A1.
  • 28km: the distance between Target A1 and the historic Kalengwa copper-silver mine.
  • 49 grams per tonne (g/t): the highest-grade silver intersection from previous drilling.
  • 0.26%: the copper grade from one of the high-grade intersections.
  • 450 by 400 metres: the current size of the mineralised area at the project.
  • 58 meters: the length of one of the high-grade intersections.
  • 73 meters: the length of another high-grade intersection.
