The Rockvale Project (EL9053) covers an area of 358km2 in the New England Orogen of NSW. The Project is located immediately adjacent to, and surrounds, Larvotto Resources’ (ASX: LRV) Hillgrove Antimony-Gold Project (see Figures 1 and 2).
Mineral Resources at the Hillgrove Deposit comprise:
- 7.2Mt @ 4.4 g/t Au and 1.3% Sb (1Moz Au and 93kt Sb)
The Rockvale Project includes the strike extensions of the geology and structures that host the Hillgrove Deposit. The Rockvale Project area is predominantly underlain by the Rockvale and Hillgrove Monzogranites which have intruded the Coffs Harbour Association siltstones, the latter two rock units being the main hosts of mineralisation at the Hillgrove Deposit. There are numerous antimony and gold prospects and occurrences within Xpedra’s project area (see Figure 2).
At the Achill Prospect, located around 12.5km northeast of the Hillgrove Antimony-Gold Mine, intermittent antimony mineralisation has been outlined over a north-south trending zone of around 130m strike length which is open to the north and south. The mineralisation is associated with quartz veins and breccias, with 1-2% disseminated stibnite, within a metamudstone/siltstone.
At the Taits Gully Prospect historical workings include the Mary-Ann and Endeavour shafts, which occur along an east-west trending fault/shear zone, within conglomerates and siltstones (Dummy Creek Conglomerate unit), which extends for at least 500m in strike length. Sampling along this structure returned assays up to 1.76g/t Au and 110g/t Ag.
Geochemical soil sampling will be carried out at the Achill and Taits Gully Prospects, together with more detailed geological mapping, to define drill targets. Additional land access agreements are currently being negotiated in the Rockvale Project area, which will allow access to further targets with historical high-grade gold, silver and antimony assay results.
