Green View Cobalt Project - 100% owned

Green View lies approximately 35 kilometres west of Broken Hill, within the highly prospective Broken Hill geological district of New South Wales. The Project is prospective for the discovery of economic critical minerals such as cobalt and copper, and covers a sequence of metamorphosed sediments, gneisses, and amphibolite of the Proterozoic – age Willyama Supergroup.

Modern cobalt exploration has been largely restricted to the area of Cobalt Blue’s (ASX: COB) Broken Hill Cobalt Project which hosts the Pyrite Hill, Big Hill, and Railway Deposits (with a global Mineral Resource estimate comprising 118 Mt at 859 ppm (0.08%) cobalt equivalent (CoEq) [i.e., 687 ppm (0.07%) cobalt, 7.6% sulphur & 133 ppm nickel] for 81.1Kt contained cobalt using a 275 ppm CoEq cut-off

Rimfire has identified three high-grade cobalt targets (Bald Hill, Staurolite Ridge, and Railway Extension) on its 100% - owned Green View Cobalt Project following a review of historic exploration activities.

Exploration was last undertaken on Rimfire’s project in the early 1980’s when North Broken Hill Pty Ltd conducted a program of geological mapping, IP geophysics and drilling at the Bald Hill prospect.

Rimfire intends to conduct drilling over the three identified high grade cobalt targets with access granted for drilling on Bald Hill and work underway to receive access to drill Staurolite Ridge and Railway Extension (which is adjacent to Cobalt Blue’s Railway Deposit).
