Bullabulling - Overview
Bullabulling is located 65km south west of Kalgoorlie, Western Australia in the highly prospective Eastern Goldfields.
Bullabulling has 2.6Moz Au in JORC inferred resource.
Key Points
- JORC inferred resource 2.6Moz Au contained gold
- 65km south west of Kalgoorlie WA in highly prospective eastern goldfields
- Nine gold resources along mineralised 12km zone
- Gold mineralisation open in all directions especially at depth where high grades intersected
- Estimated 25,000 oz Au ore at surface
- Bullabulling previous production by Resolute Mining Ltd – 371,474 oz (7.9Mt at 1.45g/t gold) during 1990s
- Existing fully licensed mine with water, road access & power
- 131km2 permitted tenements including pastoral lease
- Geological modelling identified continuous gold zones at 3 to 4 g/t Au within broad 0.5 to 1.5 g/t envelope in primary mineralisation
Bullabulling Gold Project Assets
- 2,422 hectares of granted mining tenure;
- Nine gold resources along mineralised 12 km zone;
- Ore previously mined predominantly from shallow pits (30m) and not into the primary mineralisation;
- Extensive exploration database, over 400kms of previous drill data at an average depth of 34km – approximately A$30m replacement value;
- 25,000 oz gold in dumps and ROM pads at surface
- Existing mining infrastructure
High grade drill intersections include:-
- BacchusPit: 7m@77g/tAu, 5m@14g/tAu, This e-mail address is being protected from spambots. You need JavaScript enabled to view it /tAu, 3m @ 9.16 g/t Au;
- Dicksons Pit: 4m@14.5 g/t Au;
- Hobbit Pit: 9m @ 10.5 g/t Au;
- Edwards pit: 9m @ 11.9 g/t Au
Current program focusing 2.3km area between Bacchus & Phoenix open pits – expected minimum target reserve 1m+ oz Au
Structural Study confirmed gold mineralisation can be traced through 40m spaced drill sections along entire 6km Bullabulling trend which is open to the north & south & at depth
Higher grade (3-4 g/t Au) continuous zones (100s of metres), 5-20m wide & open at depth located within lower grade halo (0.5-1.5 g/t Au)
- Previous mining focused on shallow laterite & supergene gold mineralisation – shallow pits (30-40m)
- Shallow gold mineralisation spotty & low grade with poor continuity
- 371,000oz Au mined, mostly under 50m depth
- Grade & continuity of gold mineralisation increases with depth – tonnage (& contained oz gold) expected to increase significantly
Grade Increases at Depth
Based on existing drilling data
(click the image on the right for a larger view);
- Previous mining operation focused on shallow laterite and supergene gold mineralisation – pits were shallow (30m – 40m depth).
- Shallow gold mineralisation typically spotty and low grade with poor continuity
- A total of 371,000oz Au mined, predominantly from less than 50m depth
- Grade and continuity of gold mineralisation increases with depth – tonnage (and contained ounces gold) expected to increase significantly
