Cooper Metals Ltd (ASX:CPM) has fielded more strong copper-gold assays from reverse circulation (RC) drilling at King Solomon and Python prospects within the Mt Isa East Copper-Gold Project in northwest Queensland.
The company’s drill program comprised 19 RC holes across 2,816 metres on a range of targets at King Solomon 1, King Solomon 2, King Solomon 3, Python and the Camp gossan.
At King Solomon 1, continuous copper-gold mineralisation was confirmed 170 metres below historical workings and remains open at depth.
Encouraging results
Standout assays include:
- 14 metres at 1.1% copper and 0.04 g/t gold from 44 metres, including 1-metre at 4.6% copper and 0.23 g/t gold and 3 metres at 2.7% copper and 0.07 g/t gold;
- 21 metres at 0.8% copper and 0.09 g/t gold from 158 metres, including 8 metres at 1.5% copper and 0.2 g/t gold; and
- 8 metres at 0.6% copper and 0.1 g/t gold from 128 metres, including 2 metres at 1.2% copper and 0.24 g/t gold.
Furthermore, new results from King Solomon 2 include:
- 16 metres at 0.8% copper and 0.03 g/t gold from 12 metres, including 5 metres at 2.0% copper and 0.05 g/t gold; and
- 16 metres at 0.5% copper and 0.02 g/t gold from 16 metres, including 3 metres at 1.2% copper and 0.05 g/t gold.
Cooper managing director Ian Warland said: “At King Solomon 1, recent drilling has extended the copper-gold mineralisation to around 170 metres below historical workings in hole 22MERC048A.
“Importantly, the induced polarisation survey completed late last year indicates the mineralisation is likely to extend deeper, especially at the southern end of the prospect where the response is strongest.
“Another important development is the significant shallow mineralisation intersected at the northern end of King Solomon 2 which is open at depth and along strike to the south.
“King Solomon continues to grow in size and potential for more growth is very promising.”

Drill program
The bulk of the drilling was completed at King Solomon, with 15 holes for 2,314 metres drilled. November's drill program was the third program completed by Cooper at King Solomon in 2022.
This third phase included 11 drill holes for 1,824 metres of RC drilling at King Solomon 1 prospect, drilling under historical workings and testing three plunging shoots identified in the August RC drilling program.
To recap, King Solomon 1 has steeply dipping copper-gold mineralisation hosted within an NNW trending shear zone within the Corella Formation.
Mineralisation has been traced for around 650 metres along strike, with higher grades in three interpreted plunging shoots.
Drilling at the northern end of King Solomon 2 was designed to test two target areas, with 22MERC060A a redrill of 22MERC060 testing a deeper target to the east.
