- Tin Dog debuts with a maiden 309koz gold resource
- Red Dog grows to 30koz in an updated resource
- A new NW-SE structural model opens more Tin Dog targets
Special Report: Latitude 66 has converted a revised geological model and a short burst of drilling into a 339,000oz gold resource base at Laverton, led by a maiden estimate at Tin Dog and an expanded resource at Red Dog.
Latitude 66 (ASX:LAT) has reported combined mineral resources of 10.7Mt at 1.0g/t gold for 339,000oz across Tin Dog and Red Dog, with 40% in the indicated category and 60% inferred. The resource is reported on a 100% project basis, with LAT holding an 80% interest.
Tin Dog accounts for most of the inventory with a maiden MRE of 10Mt at 1.0g/t gold for 309,000oz, comprising about 38% indicated and 62% inferred.
Red Dog, meanwhile, has an updated MRE of 0.7Mt at 1.3g/t gold for 30,000oz. That’s around 122% more contained gold than the historical remnant resource of 13,500oz that existed when Latitude entered the Laverton transaction.
Latitude 66 said the new resource ounces have been delivered at an exploration and resource-definition cost of about $2.61/oz since it entered the Laverton agreements.
The resources are reported above a 0.6g/t gold cut-off and constrained within optimised open-pit shells using an assumed A$6,000/oz gold price.
“Delivering a 339,000-ounce Mineral Resource on the Laverton Gold project is a significant milestone for Lat66, taking our global Mineral Resources to more than 900,000 ounces of gold,” LAT managing director Grant Coyle said.
A new read on Tin Dog
The maiden Tin Dog resource reflects a material change in how Latitude interprets the deposit.
Its technical review identified a previously under-recognised NW-SE structural control on gold mineralisation, with new shear-hosted lodes recognised alongside the historically understood syenite-hosted mineralisation.
That model helped delineate The Don and Wilpro lodes and supported confirmatory drilling around Brunswick, expanding the known mineralised system before the maiden estimate was completed.
Latitude says confidence in the Tin Dog geological interpretation is moderate and additional diamond drilling is required before certainty can be attributed to the structural model, although the north-west continuity of mineralisation is considered compelling.
Diamond drilling is now planned to test interpreted high-grade shoot orientations, while further RC drilling may be used to extend and upgrade The Don and Wilpro structures.
Gold country with infrastructure to match
Laverton has been a gold-mining centre since the WA gold rush of the late 1890s, while renewed exploration in the 1980s and 1990s led to new discoveries and a material increase in the region’s resource inventory.
Current action in the region includes the likes of AngloGold Ashanti’s Sunrise Dam operation, about 55km south of Laverton, which produced 232,000oz in 2025, while Genesis Minerals has a restarted 3Mtpa mill in the Laverton district and has been consolidating deposits around that processing base.
In July, Genesis agreed to acquire Vault Minerals in a deal valuing Vault at about A$5.6bn and intended to create Australia’s third-largest gold producer, with projected output of up to 700,000oz a year.
Latitude’s Tin Dog and Red Dog are on granted mining leases and the company says five operating gold processing facilities sit within 100km, giving it potential development options to assess.
New tricks at the two deposits come as gold demand in the first half of this year reached 2,522t, up 2% year on year, with a record value of US$380bn.
Spot gold then reached a more than three-month high of US$4,696.18/oz this month while gold-backed ETFs attracted US$6.4bn – their largest weekly inflow in 10 months.

A potential production pathway
Latitude’s combined resource now has 40% of ounces in the Indicated category and the deposits are considered amenable to conventional open-pit mining in the resource assumptions. Red Dog also has a history of open-pit mining.
Historical Red Dog work reported about 90% recovery in preliminary gravity and cyanide leach testwork and 92.5% during the previous mining campaign, which was completed in 2018.
Red Dog is the more advanced development proposition, with Latitude planning to progress it towards development during the second half of 2026. Tin Dog adds scale and exploration leverage, with extensions and parallel structures still to be tested under the revised geological model.
If drilling increases confidence and scale, and future studies demonstrate workable mining, metallurgy and commercial processing arrangements, Latitude could have a pathway towards gold production in one of WA’s established gold districts.
