NAMIBIA Critical Metals (NCM) has commenced the first phase of its 4,000 metre drilling programme on its Kunene Cobalt-Copper project in northern Namibia, Confidente has learned.
Two drill rigs have been mobilised to site, with one diamond drill to commence a 2,000m exploratory drilling programme, starting on the interpreted westward extension of the Dolomite Ore Formation (DOF), which reportedly hosts the Opuwo cobalt-copper-zinc deposit, and one reverse circulation drill to commence testing the Okanihova lineament.
The drill programme follows the completion of a detailed airborne electromagnetic (EM) survey covering over 720 km2 of the project area. One primary objective of the airborne EM survey was to delineate specific targets for drilling.
The first phase programme is designed to test as many accessible priority target areas as rapidly as possible along the DOF Extension, the Okanihova lineament, at Okanihova East and in the vicinity of Malachite Mountain. First analytical results are anticipated to be received in late November.
Don Burton, president of Namibia Critical Metals, said: “We have a prolific number of targets to assess at Kunene and this first phase of drilling is designed to quickly zero in on the most prospective target areas to which we could build access tracks over the past month.
“The diamond drill is being deployed to the DOF extension targets because we need to understand the detailed stratigraphy in order to recognize the DOF, which is a relatively narrow target.
“The RC drill is being directed to larger scale targets, often under cover where we can quickly determine the need for follow-up definition with diamond drilling. Given the scale of the project area we will not be able to get to priority targets in the western areas until early 2019.”
The Kunene project area is characterised by widespread base metal and associated mineralisation occurring in discrete sedimentary horizons, such as the DOF where cobalt and copper is associated with disseminations and veinlets of sulphide minerals, as well as orogenic copper, and strata bound mineralisation.
The strata-bound DOF hosts the Opuwo deposits, which occurs on the contiguous ground held by Celsius Resources, where it has been traced for over 35 kilometers. This stratigraphic package is interpreted to continue across the Kunene Project area and has now been clearly identified by the airborne EM survey over a strike length of 20 kilometers.
The Okanihova lineament is a well-defined structure with strong cobalt-copper geochemical anomalies over its north-eastern extremity; however the structure is largely under cover for over 10 kilometers to the southwest.
The Opuwo deposit is the first primary cobalt discovery in Namibia and has demonstrated the potential for this part of northern Namibia to become a significant cobalt district. Celsius has reported that the Opuwo deposit hosts a maiden JORC compliant resource of 72.0 million tonnes at a grade of 0.11 percent cobalt, 0.42 percent copper and 0.41 percent zinc in the Indicated category, and a further 40.5 million tonnes at a grade of 0.12 percent cobalt, 0.41 percent copper and 0.46 percent zinc in the Inferred category.
It is noted that the mineralisation on the Celsius property may not be indicative of mineralisation on the Kunene project area held by Namibia Critical Metals.
Namibia Critical Metals holds a diversified portfolio of exploration and advanced stage projects focused on the development of sustainable and ethical sources of metals for the battery, electric vehicle and associated industries.
