Warrantina
The tenement encompasses two historic gold fields, Forester and Warrentinna. Both fields produced high grade gold deposits in the late 1800s and early 1900s. These historic high grade quarts lodes were mined both at surface and underground, such as the Golden Mara mine which produced 3,368oz at an average of 1 oz/tonne.
Prior to Greatland carrying out historic work on the field, the surrounding areas had lacked significant modern exploration efforts.
Forester is in the north of the licence containing around a dozen historical mines.
Warrantina is in the south and contains 3 areas Renown, Derby North and Golden Mara in the southern end.
Ahead of drilling, Greatland carried out consistent geological mapping, soil sampling, rock chip sampling, primarily in the two targets areas of Forester and Warrentinna.
Such results include:
Soil sampling returned highs of 666.5ppb and 1,308ppb Au.
Rock chip samples returned highs of 44.6g/t, and 464g/t Au.
Confirming the historic reports of the high-grade nature of mineralisation in the area.
The sampling extrapolates mineralised strike lengths of up to 6km in both areas with other areas of the tenement yet to be fully evaluated.
The company has drilled over 3,750m to date with over 3,500m of historical drill data also obtained for analysis.
Drilling results show gold mineralisation is developed from surface, with highlights including:
26m@2.32g/t Au
5m@29.26g/t Au
3m@9.34g/t
2m@13.71g/t Au
1m@19.77g/t Au
1m@103.07g/tAu
Maiden diamond drill programme at Derby North prospect intersects high-grade gold mineralisation and increases depth extent of known mineralisation.
• Best results include:
21.7m@ 3.3g/t au from 9.3m(2019WTD001), including 2.2m @ 12g/t Au from 10.8m
11.7m @ 2.8g/t gold from 118m (2019WTD002)– a new zone of gold mineralisation beneath previous drilling
43m @1.5g/t au from 10m (2019WTD003)
Gervaise Heddle, CEO at the time commented: “These positive results from our maiden diamond drilling campaign at Warrentinna further increase the depth extent of the known mineralised zone and clearly demonstrate the potential for a significant gold mineralised system at Derby North
