The AIM-listed firm said that two lines of augering have so far been completed on the 70% owned Kisinka licence acquired in December 2017 - one across the southeastern part and the second towards the northwestern part of the licence.
ABM said the augering penetrates the surface to extract soil samples from closer to the bedrock which is useful in areas of soil cover like Kisinka.
The Africa-focused exploration company said given the positive results from the northern line, the decision was made to extend the auger programme.
The firm said it intends to submit soil samples for laboratory analysis in Johannesburg shortly. It added that given the large size of the iicence, and the distance between the two lines of augering, consideration will also be given to running a soil sampling programme on a grid pattern across the whole licence area.
Continues to evaluate other copper-cobalt opportunities in the DRC
ABM added that whilst its current exploration focus is on Kisinka, it continues to evaluate other copper-cobalt opportunities in the DRC. ABM retains the option over a second licence, Sakania, and expects to investigate that licence in due course.
The group said it has also been approached to look at other licences within the DRC, some of which have had geological work already completed on them and which confirms high-grade copper/cobalt mineralisation.
Roger Murphy, CEO of ABM, said: “The next round of field work on Kisinka, which could involve soil sampling or further augering, will be formulated based on ongoing results. We will update the market with these as they become available.”
He added: "In the meanwhile we are excited by the quality of opportunities we are being offered. We continue to assess these opportunities and will update the market as appropriate."
