Latest Metallurgical Testwork News

Viking Mines’ tailings sampling at Nevada’s Linka Tungsten Project reveals minimal leftover tungsten, affirming strong historical recovery and bolstering confidence before maiden drilling in July.

Pivotal Metals has extended its diamond drilling program at the Lorraine Mine East in Quebec, targeting untested copper-nickel and gold anomalies adjacent to a historic mine. The move aims to explore both magmatic sulphide and vein-hosted mineralisation, with drilling underway at the Shanty Lake target and a resource update due for Horden Lake.

Sunstone Metals is pushing the boundaries of its Bramaderos gold-copper project in Ecuador, with all 20 holes assayed in the current drilling campaign delivering long mineralised intersections. The Porotillo porphyry system alone now extends mineralisation over an area of roughly 500m by 200m beyond the existing 3.6Moz resource.

Lion Rock Minerals (ASX: LRM) has expanded its high-grade rutile footprint at the Minta Project in Cameroon, revealing a 130km² residual rutile corridor with peak rutile grades up to 72.7% heavy mineral and natural rutile nuggets exceeding 98% TiO2 purity.

Black Bear Minerals has extended high-grade silver intercepts outside its existing Shafter Mineral Resource Estimate, with assays up to 1,333g/t Ag and promising polymetallic potential, advancing resource validation and mine restart plans.

Terra Metals has reported thick, continuous platinum group metal-copper-nickel sulfide mineralisation over a 950m strike at the Southwest zone of its Dante Project, with deeper assays pending and exploration advancing rapidly.

OD6 Metals has unveiled a series of new high-priority drill targets at its Quinn Fluorspar Project in Nevada, highlighted by exceptional soil fluorine values that suggest extensive high-grade mineralisation over an 8km corridor.

Godolphin Resources’ mineralogical study at Lewis Ponds reveals talc dilution in lead concentrate, proposing a pre-flotation step that could double lead grade and boost precious metals recovery.

Black Canyon has won a $264,800 WA government grant to fund a detailed gravity survey and deep RC drilling at its Wandanya manganese project, accelerating its path to a maiden resource estimate.

Resouro Strategic Metals has unveiled a robust Preliminary Economic Assessment for its Tiros Titanium and Rare Earths Project, signalling a post-tax NPV of US$715 million and a 44.2% IRR over 20 years. Meanwhile, binding agreements for mining and processing at the Novo Mundo Gold Project promise to unlock additional value.

Heavy Rare Earths Limited has initiated a strategic review of its Cowalinya rare earth project, focusing on heavy rare earth oxides critical for energy and defence sectors. The review aims to unlock value from high-grade zones within a substantial JORC resource through expert reinterpretation and targeted metallurgical testing.

Toubani Resources (ASX: TRE) is acquiring a near 20% equity interest in Avanti Gold (CSE: AGC) via a share swap, gaining exposure to the Misisi Gold Project in the DRC with a 3.1 million ounce inferred resource.
