WA Mining Weekly May 25 - 31
Majors moving, juniors circling: the Dundas rush, Catalyst's Plutonic play, and the ground set to expire this week.
This Week’s Big Stories
Dundas Expiry Triggers Five-Way Scramble for Released Ground
Five applicants have piled onto a block of recently expired ground in the Dundas area: Peg Resources, Amery Holdings, Mining Equities, Forrestania Resources and Voyage Minerals. The history explains the rush. This ground has been pegged 53 times in nearly 101 years, with earlier scrambles clustering around 1970, 1980 and 1981. The draw now looks to be lithium: the Earl Grey pit at Mt Holland (Wesfarmers and SQM) sits about 80 km away in the southern Yilgarn. Amery and Mining Equities are no newcomers either, holding 53 and 77 tenements in the region respectively, and the surrounding ground is already tightly held by the likes of Charger Metals, Flynn Gold and Rubix Resources.
Catalyst Metals moves to close out its Vango takeover
Catalyst shifted more than a hundred tenements around its corporate structure this week, the administrative tail end of its $66 million takeover of Vango Mining. Vango brings a 1 Moz resource at 3.3 g/t gold across 40 km of strike in the Marymia-Plutonic belt, ground that has carried fragmented ownership for years despite its prospectivity. Paired with Catalyst’s earlier merger with Superior Gold, which delivered the adjacent Plutonic mine and its 3 Mtpa mill, the strategy is straightforward: feed higher-grade ore from targets like K2, Trident and Old Highway into the Plutonic plant to drive unit costs down. The consolidated belt reportedly holds around 7 Moz.
CGN Resources cements its Leonora footprint with Desdemona
CGN picked up 20 tenements covering roughly 16,000 hectares, almost all transferring from Kin West, completing its acquisition of the Desdemona Project from Patronus Resources (formerly Kin Mining). The deal was all-scrip, about $500,000 in shares, structured to keep CGN’s cash intact. That landholding now puts CGN at around 386 km² in the Leonora Gold Province, along strike from Gwalia and King of the Hills. With roughly $2.5 million preserved for drilling, the company is lining up maiden RC programs at the Christmas Well and Panhandle prospects, both barely touched since the early 2000s and shallow enough to give CGN a walk-up drill target without the cost of starting from scratch.
