Accrington Cu-Zn Skarn
Accrington is a very large skarn/ carbonate replacement mineralised system hosting numerous small-scale historical workings and occurrences across a 1.8km by 1.2km area. Historical mining focused on high grade zinc-lead-silver-copper-gold veins and copper-zinc skarn.
Accrington prospect features include:
- Skarn alteration and mineralisation across an area 4km long by up to 2km wide, with widespread outcropping mineralisation and historical small workings within the central 1.8km by 1.2km Accrington prospect;
- Wide areas of high-temperature garnet-pyroxene and magnetite skarn at Accrington associated with copper-zinc mineralisation;
- Historical drilling which intersected thick zones of copper-zinc mineralisation with potential higher grade copper-zinc mineralisation at depth; and
- Intrusive porphyry and aplitic dykes, which are common over Accrington, some mineralised with copper-gold and related to either the Cactus Canyon prospect or another possible mineralised porphyry intrusion.
Widespread mineralisation at surface, including wide intercepts of copper-zinc mineralisation in historic drilling, outcrops of further untested copper-zinc skarn and the scale of the Accrington skarn (1.8km by 1.2km), present strong evidence of potential for a large tonnage deposit at the prospect.

Horn Zn-Pb-Ag Skarn
The Horn prospect centres on the historic high-grade Horn Silver Mine, where historical production amounted to 18,159,901 ounces of silver and 178,321 tonnes of lead from 934,724 tonnes of crude ore across several decades of production until the 1960s . Miners focused on lead-silver production, despite the ore-body hosting zinc-rich ore.
Subsequent drilling has intersected areas of high-grade zinc within and below the mine, with underground channel sampling delineating further zinc mineralisation, but insufficient to define a Mineral Resource Estimate.
The Horn Silver deposit occurs as a tabular, near vertical to steeply west dipping, breccia-hosted zone, which prior to mining indicated had a north-south strike length of 215m, a vertical extent of about 290m and a maximum recorded width of up to 55m.
The Company believes that the Horn prospect has potential for a high grade zinc-lead-silver resource.
