Latitude 66 (ASX:LAT) has defined a combined mineral resource estimate (MRE) of 10.7 million tonnes (Mt) @ 1 gram per tonne gold (Au) for 339,000 ounces at its Laverton Gold Project in Western Australia.
The estimate covers a maiden resource at the Tin Dog prospect and an updated resource at the Red Dog prospect. It is reported on a 100% project basis, with Latitude holding an 80% interest.
Around 40% of the combined resource is indicated, with the remaining 60% inferred.
Tin Dog contributes 10Mt @ 1g/t Au for 309,000 ounces, including 38% in the indicated category. Meanwhile, Red Dog hosts 710,000 tonnes @ 1.3g/t Au for 30,000 ounces, including 56% indicated. This represents a 122% increase from its historical remnant resource of 13,500 ounces.
The estimate draws on 646 holes drilled by Latitude and previous operators. Latitude completed 6,451m of reverse circulation (RC) drilling after executing its option agreement in November 2025.
Managing Director Grant Coyle says the results support the company’s revised geological interpretation at Tin Dog.
“The result validates our geological model at Tin Dog, where the identification of a previously under-recognised NW–SE structural corridor has contributed to a substantial maiden mineral resource, alongside a 122% increase in the mineral resource at Red Dog,” Coyle says.
“Importantly, these additional ounces have been delivered at a highly competitive discovery cost of approximately $2.61 per resource ounce, reflecting the effectiveness and disciplined approach of our exploration team.”
Latitude calculates the $2.61 figure after excluding Red Dog’s pre-existing 13,500-ounce resource. The costs include drilling, assays, field supplies, accommodation, and personnel associated with the drilling program.
The revised interpretation identified new shear-hosted lodes alongside the previously recognised syenite-hosted mineralisation. At Red Dog, step-out drilling extended the shallow system beyond the historically mined open pit.
Both resources are constrained by optimised open-pit shells using an assumed gold price of $6,000 per ounce and are reported above a 0.6g/t Au cut-off grade.
The pit shells also contain an estimated 260,000 ounces at grades between 0.2g/t and 0.6g/t Au. This lower-grade material is excluded from the reported MRE, and its potential contribution remains subject to further mining, metallurgical, and economic studies.
Tin Dog and Red Dog are located on granted mining leases within 100km of five operating gold-processing facilities in the northern Goldfields.
Latitude says it plans to complete diamond drilling at Tin Dog to test the orientation of interpreted higher-grade shoots. It is also considering further RC drilling to extend the resource and follow up the Don and Wilpro structures.
The resource update follows Latitude’s completion of the sale of its non-core Piastri Project to Capricorn Metals (ASX:CMM) for $1.5 million in Capricorn shares. Latitude says the transaction allows it to direct more capital towards Laverton and its Kuusamo Schist Belt (KSB) Project in Finland.
The Laverton resource lifts Latitude’s reported ownership-weighted gold inventory across WA and Finland to 918,000 ounces.
Latitude 66 is an Australian mineral exploration and development company focused on gold and critical mineral projects in Finland and WA. Its KSB Project hosts 650,000 ounces of gold and 5,840 tonnes of cobalt.
