“UD Lode” extended to over 200m strike length
Five new zones of mineralisation intersected
- UD Lode has been intersected in five of the six drill holes reported to date, and has been traced over a 200m strike length and remains open along strike
- Four new zones of copper +/- tin +/- silver mineralisation have been intersected
- The table below summarises all intercepts from the current drill programme

* Results for UD21_001 were reported
* Reported intercepts are drilled lengths. True thicknesses of the mineralised intercepts are estimated to range between 30-60% of the drilled lengths.
* The results reported to date represent a total of 3,042m of drilling. A further 5,000m – 6,000m is planned.
The linked plan map and cross section provide an overview of where drilling has been conducted to date, and where the zones of mineralisation occur. Contrary to initial interpretation, UD Lode dips south at approximately 80 degrees, counter to the predominant trends in the area.
Results for drill holes UD21_006 and UD21_008 to UD21-010 will be released as received.
GEOLOGY AND MINERALISATION
The geology at United Downs comprises metasediments (locally termed “killas”), which overlie an intrusive granite body. All the historic copper mines within the area (United Mines and Consolidated Mines) and the historic tin, copper and zinc mines (
The mineralisation is primarily hosted in narrow, steeply dipping vein or “lode” structures, and consists of cassiterite (tin), chalcopyrite (copper) and sphalerite (zinc) with other copper minerals such as chalcocite and bornite occasionally present.
United Mines and Consolidated Mines, located 200m south and 400m north of UD Lode, respectively, operated between the early 1700s and the 1870s, mining high-grade copper ores (reported grades of 7.5% copper) to depths of up to 500m below surface.
