Royal George

The Royal George prospect is located in the southern portion of EL27/2004 approximately 17km east of the township of Avoca.

Royal George Project Area

Mineralisation at the Royal George prospect is hosted within a series of steeply dipping, northwest striking greisens. Individual greisens are typically 1.5m wide and contain disseminated cassiterite. Groups of greisens have been recorded up to 20m wide in places.

An updated Inferred Mineral Resource was released by an Independent Consultant in March 2014 that was compiled to the JORC Code (2012) standard. The results of this Inferred Mineral Resource for various tin cut-off grades are summarised below.

Category Tonnes Sn Grade Sn Cut-Off
Inferred 474,227 0.25% 0%
Inferred 281,485 0.33% 0.20%
Inferred 210,795 0.36% 0.25%

Royal George Deposit – JORC Code (2012) Inferred Mineral Resources

Mineralisation was discovered in the Royal George prospect in the 1880’s and since that time the region has seen various exploration and mining campaigns.

  • 1911–1922; small-scale mining activities produced 170,000t @ 0.65% Sn from surface workings and two underground levels.
  •  1965–1971; Cornwall Coal Company with assistance from the Tasmanian Mines Department conducted underground mapping and drilling. Two inclined shafts were deepened and two deeper levels (No. 3 and 4) levels were later developed.

Historical exploration to date has identified sufficient near surface and underground tin mineralisation to define the Inferred Resources detailed above. Further drilling with modern lab and quality control is required to advance the status of the Inferred Resource. Sulphides are also present at Royal George and require further work to delineate their occurrence and impact.
