The San Antonio and Roswell deposits
The Tomingley Gold Extension Project is founded on the San Antonio and Roswell (SAR) gold deposits, located immediately to the south of the existing Tomingley gold mining operation.
Like the Caloma and Wyoming gold deposits to the north, the SAR deposits are interpreted as orogenic gold systems positioned within a major structural zone. Their similar geology to the Caloma and Wyoming deposits make them ideal feedstock for the existing processing plant.
The initial Inferred Resource for the Roswell deposit was announced on 28 January 2020 and for the San Antonio deposit 20 April 2020, both in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC 2012).
San Antonio Mineral Resources (as at 30 June 2020)
| Deposit | Resource category | Cut-off | Tonnes (Mt) | Gold grade (g/t) | Gold metal (koz) |
| San Antonio | Inferred | 0.5g/t Au | 7.92 | 1.78 | 453 |
Roswell Mineral Resources (as at 4 November 2020)
| Deposit | Resource category | Cut-off | Tonnes (Mt) | Gold grade (g/t) | Gold metal (koz) |
| Roswell | Indicated | 0.5g/t Au | 7.88 | 2.07 | 524 |
