US$0.5M Grant from BHP for Copper Porphyry Exploration, Kazakhstan

&

Appointment of Director

East Star Resources Plc (LSE:EST), which is defining mineral resources in Kazakhstan for the energy revolution, is delighted to announce it has been selected to receive a grant of up to US$0.5 million from BHP under the 2024 BHP Xplor programme to initiate a copper porphyry exploration strategy in Kazakhstan.

Highlights:

Alex Walker, East Star CEO, commented:

"We are extremely proud that BHP has chosen to work with East Star with the provision of $500,000 of non-dilutive grant funding to look for major new copper porphyry deposits in the region. Porphyry deposits are the primary deposit style for copper production in the world and Kazakhstan is host to several exceptional but significantly under explored regions that contain a number of world-class copper porphyry mines. This is an exciting new strand to our copper strategy as we progress both porphyry and VMS exploration."

Alongside this, we are delighted to welcome Chris van Wijk as a Non-Executive Director. Chris has exceptional exploration pedigree, having conducted joint venture management and project evaluation for major mining companies and having been involved in several exploration success stories. Chris enabled East Star to develop this opportunity and his technical expertise will be a valuable addition to our Board and exploration portfolio."

Head of the BHP Xplor Program, Charlee Johnson, commented:

"The diversity and quality of the submissions amongst the applicants is amazing and inspiring. We are excited to partner with East Star and help bring their ideas and passion for their exploration projects to life. We aim to accelerate this process and create disruptive results with new concepts, data and testing opportunities." 

Copper Porphyry Exploration Strategy

East Star has developed a strategy of regional target generation for copper porphyry deposits, principally focussed on the Balkash-Ili magmatic arc, host to the Kounrad deposit (~650Mt @ 0.59% Cu) and Aktogai-Aidarly (~2.5Bt @ 0.39% Cu). By applying modern mineral systems concepts with advanced desktop analytical techniques and on the ground geological confirmation, East Star intends to secure several exploration licences within the area of interest for further field work. The BHP Xplor grant will be directed towards licence costs, field programmes, desktop evaluation work, and staff and administrative costs in the execution of the work plan. The programme will be managed by East Star with guidance from the BHP Xplor and wider expert team.

About BHP Xplor

BHP Xplor is a cohort-based world-first accelerator programme, dedicated to unearthing new critical mineral deposits by uniting BHP experts, thought leaders and innovative mineral explorers to offer participants with the opportunity to accelerate their exploration concepts and the potential to establish a long-term partnership with BHP. The programme offers participants funding, mentorship and coaching, and connection into BHP's network of suppliers and service providers.

BHP Xplor merges concepts from both venture-capital and early-stage accelerators, to establish a fit-for-purpose exploration portfolio of innovative, early-stage mineral exploration companies and helps drive their exploration campaigns. The programme provides candidates with a one-off, non-dilutive grant of up to US$500,000, together with in-kind services, mentorship, networking opportunities with industry and investors and connections. The grant is a once off opportunity and there are no obligations or commitments on East Star beyond the conclusion of the Xplor programme; however, East Star has committed to grant BHP certain pre-emption rights with respect to investments in East Star or its projects within the programme.

The Xplor programme is designed to create disruptive results in mineral exploration by identifying new concepts, leveraging new data and testing opportunities at a much faster pace than discoveries to date.

Appointment of Chris van Wijk as Non-Executive Director

East Star is pleased to announce the appointment of Chris van Wijk as a Non-Executive Director of the Company effective immediately. Chris is an experienced geologist who specialises in project evaluation and project generation and developed the porphyry exploration strategy with East Star.
