Theta Gold during the last 3 years managed to double its mineral resources through an extensive historic data ditgitising process (data from historic production/sampling since 1873), as well as a >20,000 metres drilling program. (Figure 1)
In May 2019 the Company updated its latest Mineral Resources tables below.

Mineral Resources tables
Table 1: Combined Mineral Resources as at 1 May 2019
- Columns may not add up due to rounding.
- Gold price used for the cut-off calculations is USD1,500/oz.
- UG Mineral Resources are reported at a cut-off of 160 cm.g/t, open pit at 0.5 g/t and 0.35 g/t, tailings and rock dumps at 0.35 g/t.
- Fault losses of 5% for Measured and Indicated, 10% for Inferred Mineral Resources.
- Mineral Resources are stated as inclusive of Ore Reserves.
- Mineral Resources are reported as total Mineral Resources and are not attributed.
Table 2: Theta Project Ore Reserves for MR83 Only, 1 May 2019
The Ore Reserves exclude Inferred Mineral Resources.
- Totals in the Ore Reserve may not add-up due to rounding.
- Mineral Resources are for MR83 only and excludes MR341.
- No Inferred Mineral Resources are included in the Ore Reserve.
Table 3: Total Theta Project – Mineral Resources, 1 May 2019
- Theta Project (Theta Hill, Browns Hill and Iota) cut-off is 0.35 g/t;
- The gold price used for the cut-off calculations is USD 1,500 / oz;
- Geological losses applied are 10% for inferred and 5% for Indicated and Measured;
- Theta Hill and Browns Hill – Upper Theta Reef, Lower Theta Reef and Beta Reef are diluted grades over 100cm;
- Historical mine voids have been depleted from the Mineral Resource;
- The inferred Mineral Resources have a high degree of uncertainty and it should not be assumed that all or a portion thereof will be converted to Ore Reserves;
- Mineral Resources fall within the mining right MR83 and MR341.
