Cyprium Metals Limited (ASX: CYM) has reported first diamond core results from phase 1 of the 1,328 metre diamond drilling programme within its Nanadie Well Copper-Gold Project in WA.
The Phase 1 diamond drilling programme has continually intersected consistent sulphide mineralisation at shallow depths
The company said that the phase 1 diamond drilling programme has continually intersected consistent sulphide mineralisation at shallow depths ranging from 45m to 290m.
Standout results from Nanadie Well phase 1 Diamond Drilling included 143.8m @ 0.7% Cu from 25.0m including 2.5m at 2.1% Cu from 77.8m including 0.7m at 5.1% Cu from 79.5m; 4.0m @ 2.2% Cu from 181.0m including 2.0m at 3.6% Cu from 182.0m; and 1.0m @ 1.4% Cu from 196.0m. CYM noted that gold assay results are pending.
Cyprium noted that extensive shallow sulphide copper-gold intersection is continuing immediately below the previously announced oxide copper-gold halo.
Nanadie Well diamond drilling programme
The Nanadie Well Project is located ~650km north east of Perth and ~75km south east of Meekatharra in the Murchison District of Western Australia, within mining lease M51/887.
The company had conducted the phase 1 diamond drilling programme at the Nanadie Well Copper-Gold Project in December 2020 and January 2021.
The 1,328 m drilling was primarily designed to test the sulphide mineralisation below 50m depth at the deposit. There is an extensive shallow sulphide copper-gold intersection continuing immediately below the oxide material derived from the layered mafic intrusive unit that has been outlined in the previous Reverse Circulation (RC) drilling announcements and quarterly reports.
High-grade DD results
The company reported that near-surface oxide and extensive sulphide mineralisation were identified during this DD programme, which is open along strike to the north and south and across strike to the west. CYM said that the mineralisation does not outcrop and is covered by 1 to 25 metres of transported material.
Nanadie Well phase 1 Diamond Drilling results from NWD2004 included 143.8m @ 0.7% Cu from 25.0m including 2.5m at 2.1% Cu from 77.8m including 0.7m at 5.1% Cu from 79.5m; 7.9m @ 2.9% Cu from 82.1m including 5.9m @ 3.6% Cu from 82.1m including 1.0m at 10.9% Cu from 86.0m; 6.0m @ 2.2% Cu from 92.0m including 3.2m @ 3.9% Cu from 94.8m including 0.7m at 11.6% Cu from 94.8m; 25.0m @ 0.8% from 139.0m, including 3.0m @ 2.2% Cu from 161.0m including 1.0m at 4.6% Cu from 161.0m; 4.0m @ 2.2% Cu from 181.0m including 2.0m at 3.6% Cu from 182.0m, and 1.0m @ 1.4% Cu from 196.0m.
The company said that the preliminary investigations of the Nanadie Well deposit data indicate potential for oxide and sulphide mineralisation over the currently identified strike of 750 metres.
What’s next?
The company said that further resource definition and extension drilling programmes are currently being planned. CYM said that geophysical programmes have been conducted and undergoing compilation and review.
Cyprium said that the results from this phase 1 diamond drilling, the phase 1 RC January 2021 campaign, and subsequent drill programmes will be used in the preparation of a JORC 2012 compliant mineral resource estimate for Nanadie Well during 2021 for inclusion in the Murchison Copper-Gold scoping study.
The company said that the Cue and Nanadie Well Copper-Gold projects are included in an ongoing scoping study, to determine the parameters required to develop a copper project in the region, which provides direction for resource expansion work.
Management comments
Cyprium Executive Director Barry Cahill said: “We are excited to announce the assay results from the first hole of the phase 1 Nanadie Well diamond drilling campaign that was completed earlier this year. Whilst we are yet to receive the remaining assay results, all of the Nanadie Well diamond drill holes have visible copper mineralisation in the sulphide zone ranging from a depth of only 45 metres through to 290 metres.
“The extensive deposit is very shallow and broad, which is ideal for open pit mining”
These fantastic results demonstrate a very shallow copper mineralised system that has oxide mineralisation from surface which extends well into the sulphide mineralised zone, which is open at depth. The extensive deposit is very shallow and broad, which is ideal for open pit mining.
Diamond drill hole NWD2004 is mineralised consistently right through to a depth of 210 metres. Downhole geophysics has been conducted from the diamond drill holes to assist in the planning of the phase 2 drilling campaigns. We are delighted with our drilling results to date at the Nanadie Well project, which forms part of our exciting Murchison Copper-Gold project.”
