The proceeds from the CLN conversion shall be applied primarily to advance the Company's copper exploration programmes in the East Region of Kazakhstan and to assess new opportunities. In addition, funds will cover general working capital. Alex Walker, East Star CEO, commented: "We are pleased to have secured the full CLN conversion from Endeavour, resulting in Endeavour becoming a substantial shareholder in East Star. This strategic investment builds on our US$25 million joint venture agreement with Endeavour for gold exploration and provides capital to simultaneously advance base and precious metals exploration across Kazakhstan's highly prospective East Region."
