The explorer has a 40% stake in the project, though it is in the process of increasing that to 80%, and the new programme aims to test the deposit at depth as well as investigate potential extensions to the deposit.
Additionally, the company highlighted that metallurgical test work will assess the potential for a large-scale heap leach operation.
"Asiamet is very pleased to advise the commencement of drilling on its large-scale Beutong porphyry copper-gold project,” said Peter Bird, Asiamet chief executive.
“We have been looking forward to the opportunity to daylight the intrinsic value of this asset since it was acquired in 2015 and having recently secured long-term tenure we are now well placed to re-activate drilling and development activities at a time when copper prices are rising and advanced, large scale projects with excellent nearby infrastructure are scarce. “
Bird added: “As the scale and grade of the Beutong deposit becomes more widely recognised we would expect to see a significantly enhanced level of interest in the Company and its activities.
“We look forward to reporting the results of the drilling and metallurgical programmes at Beutong, along with results from Feasibility studies at BKM and further exploration at BKZ and other prospects in the BK district."
In a separate statement, Asiamet also announced the appointment of Liberum Capital as its corporate broker.
The group said "Liberum will work in conjunction with the Company's existing broker Optiva Securities and other key advisors in respect of various ongoing projects the company is undertaking as part of a definitive value driven strategy."
