There are five mills located within 100km of the project site, providing potential toll treatment opportunities for fast-tracked development.

The Project comprises 17 tenements, including:

  • 4 granted Mining Leases
  • 1 granted Prospecting Licence
  • 6 Exploration Licences
  • 6 Exploration Licence Applications

Red Dog

The Red Dog deposit is located on the east flank of the Mt Hornet Fault, a major N–NNW trending ductile shear zone recognised as a key control on mineralisation in the area. It is interpreted to be the main control on the Butcher Well deposit located ~15km to the north, which contains an Inferred MRE of 2.7Mt @ 3.84g/t Au for 0.33Moz.

Mineralisation that was mined from the open pit is confirmed as flat-lying, shallow mineralised horizon, typically 2–3m thick, occurring from approximately 3m depth and ranging up to 14m thick. The mineralisation remains open in several directions with significant widths of gold mineralisation extending into the walls of the existing open pit.

Significant intersections that exist outside of the historically mined open pit were previously reported by Matsa Resources (ASX: MAT) and include:

  • 4m @ 7.3g/t Au from 13m (18RDRC335)
  • 6m @ 4.8g/t Au from 22m (18RDRC122)
  • 2m @ 3.7g/t Au from 14m (19RDDD001)
  • 7m @ 3.4g/t Au from 11m (18RDRC142)
  • 7m @ 3.3g/t Au from 23m (17RDRC087)
  • 6m @ 3.2g/t Au from 13m (17RDRC072)
  • 4m @ 2.4g/t Au from 11m (17RDRC015)

Red Dog Resource

The original Red Dog Mineral Resource was reported in accordance with the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code 2012) by Matsa Resources in 2018. The mineralisation was partially mined, with historical production from the existing open pit totalling 12,704oz Au at an average grade of 2.3 g/t Au. Following depletion of this mined inventory, the remaining Mineral Resource includes 231,000t at 1.82g/t Au for 13,500oz Au, reported above a 0.5 g/t Au cut-off grade. This revised figure represents the in-situ portion of the deposit remaining after historical extraction and provides the basis for ongoing technical and economic evaluation.

Tin Dog

Mineralisation at Tin Dog Hill is characteristic of an Intrusive-Related Gold System (IRGS), with gold hosted within and adjacent to a syenite intrusive complex. The syenite stock and dyke system has intruded sheared andesitic volcaniclastics but is itself relatively undeformed.

Gold mineralisation is associated with quartz vein arrays and pervasive silica–sericite–hematite–pyrite alteration within the syenite, along its margins, and extending into the andesitic host rocks. Higher-grade results, including 9.7m @ 3.4g/t Au (TDD002) and 16m @ 2.9g/t Au (TDRC111) demonstrate excellent strike continuity and suggest potential for depth extensions along the western intrusive margin.

This mineralisation style is comparable to other syenite-associated gold systems in the Eastern Goldfields, such as Jupiter (ASX: BTR, Laverton) and King of the Hills (ASX: RED, Leonora).

These analogues highlight the potential for syenitic intrusions to act as structurally focused gold traps, and the strong alteration footprint at Tin Dog reinforces the potential for substantial resource growth through systematic drilling.

The area has been extensively worked by prospectors with many historical surface workings observed. Previous explorers include Billiton, Newcrest, Sons of Gwalia and Saracen. Compilation of historic data is ongoing with significant wide, high-grade results highlighting the potential of the area including5:

  • 6m @ 13.8g/t Au from 20m (RTDF069)
  • 9.7m @ 3.4g/t Au from 54m (TDDH002)
  • 16m @ 2.9g/t Au from 55m (TDRC111)
  • 7m @ 2.9g/t Au from 47m (TDRC112)
  • 23m @ 1.9g/t Au from 37m (19RDRC023)
  • 8m @ 1.8g/t Au from 22m (TDRC108)
  • 7m @ 1.5g/t Au from 105m (TDDH006)
  • 11.02m @ 1.3g/t Au from 98.32m (TDDH005)

Regional Tenure

Outside the main Red Dog and Tin Dog granted Mining Leases, the broader tenure captures multiple structural corridors associated with the Laverton Tectonic Zone (LTZ), a region hosting numerous multimillion-ounce deposits.

Recent exploration by adjacent explorers, including Solstice Minerals (ASX: SLS) and AngloGold Ashanti, has returned primary mineralisation from prospects along strike from Lat66’s newly acquired ground. Key results include:

  • Edjudina Range:
    •  16 m @ 1.13 g/t Au (EDRRC001)
    •  2 m @ 11.1 g/t Au (EDRRC003)
  • Bluetooth:
    •  32 m @ 1.7 g/t Au (BTHRC045)
    • 20 m @ 1.98 g/t Au (BTHRC026)

This regional tenure acquisition positions Lat66 to pursue near-term resource growth at Red Dog and Tin Dog while systematically advancing a pipeline of high-priority regional exploration targets within a proven structural corridor.
