Cobre, BHP start drilling at Botswana copper venture

01 april 2025

Cobre has begun a diamond drilling programme in collaboration with diversified miner BHP at the Kitlanya West project in Botswana, targeting copper-silver mineralisation.

It said the drill programme forms part of the recently announced BHP earn-in to joint

venture agreement and includes three deep mineral systems holes that will target large anticlinal trap-sites identified in seismic sections and provide insights into the deeper basin architecture.

“In addition to testing for copper/silver mineralisation in compelling trap-sites, drill results will answer a variety of key questions assessing the potential for the northern KCB margin to host large Tier 1 deposits,” said Cobre chief executive Adam Wooldridge.

“Results from this important phase of work will be used to further refine our seismic-driven targeting strategy."

This phase of work forms the first part of a larger A$11 million ($6.9 million) exploration budget for the 2025/26 period, which includes further seismic survey along with a number of deep test holes designed to assess the potential of both of Cobre’s Kitlanya projects to host Tier 1 copper-silver deposits.
