THE DRILL SERGEANT: Ardea Resources (ASX: ARL) reported an updated JORC 2012-compliant Mineral Resource Estimate (MRE) for the Highway nickel deposit within the company’s 100 per cent-owned Kalgoorlie nickel project (KNP).
Ardea Resources considers the Highway deposit an integral element in a proposed mining and ore processing infrastructure development at the KNP Goongarrie Hub.
The Highway resources extend over a strike length of 5.7km and are located on a granted mining lease (M29/214) with Native Title Mining Agreement in place.
Ardea sees Highway operating as a satellite mining operation to the Goongarrie Hub deposits with high-grade ore trucked 30km south along the Goldfields Highway to a processing plant to be constructed immediately east of the high-grade Goongarrie South deposit.
“The Highway resource upgrade is an outstanding result, which when combined with the February 2021 Goongarrie resource update, has defined 67.5 million tonnes of Measured and Indicated mineral resource at one per cent nickel and 0.07 per cent cobalt (681kt nickel and 49kt cobalt) which are available for conversion to reserve as part of Ardea’s KNP, Goongarrie Hub feasibility study,”
“Ardea management have prescribed metallurgical circuit reliability as an essential design element; with the availability of this added resource an important step along that journey.
“More significantly, reflecting the detailed mineralogical material type work in the current study, we now have a well-defined source of mineralised neutraliser.
“This has a significant potential value upgrade for the KNP financial model, as it is expected to introduce additional nickel units to the project production profile.
“Based on the 2021 MRE, we have selected diamond drill core hole sites in proposed future Highway and Goongarrie pit locations to acquire drill core for our H2 2021 bench-scale metallurgical programs.
“A core drilling contract was let for mid-July 2021.
“The total KNP MRE is now 830 million tonnes at 0.71 per cent nickel and 0.046 per cent cobalt (5.9Mt nickel, 380kt cobalt).
“This is a world-significant asset located in an infrastructure rich location, within the best operating jurisdiction in the world.”
