UPDATE ON DUE DILIGENCE

LONDON: 5 MARCH 2015 - ECR Minerals plc advises that further to its announcements dated 18 December 2014 and 20 February 2015, the Company’s due diligence in respect of Mae Fah Mining Co., Ltd (“Mae Fah”) and the Phang Nga lithium-tantalum-tin project in Thailand has been completed, and ECR has decided not to proceed with the transaction.

Stephen Clayson, Chief Executive Officer of ECR, commented:

“While there were interesting aspects to the Phang Nga project, in the final determination our due diligence standards were not met. ECR continues to review a small number of other potential new projects, but would only proceed with an opportunity which the directors believe is of sufficient merit to materially strengthen ECR as an investment proposition.

Separately, we are continuing to advance the Itogon and SLM gold projects in the Philippines and Argentina, respectively. We look forward to announcing results from our announced exploration programmes, which include diamond drilling at the Itogon project, in due course.”

ABOUT ECR

ECR is a mineral exploration and development company with, among other interests, the right to earn a 50% interest in the Itogon gold project in the Philippines. Itogon is an advanced exploration project located in a gold and copper mining district in the north of the Philippines.

ECR has a 100% interest in the SLM gold project in La Rioja Province, Argentina, the exploration strategy for which is to delineate multiple medium to high grade, low tonnage deposits suitable for advancement to production on a relatively low capital, near term basis.

ECR continues to review potential new investments on a highly selective basis, with a concentration on precious, base and strategic metals projects in Asia and South America.
