Zenith Minerals increases resource estimate at Develin Creek Project in Queensland

Zenith Minerals (ASX:ZNC) reports it has increased the Mineral Resource Estimate (MRE) at the company’s 100% owned Develin Creek Project in Queensland.

Zenith reports that following a series of drilling campaigns at Develin Creek it now has a 90% increase in tonnage and a 30% increase in overall contained metal from the previous estimate announced on 15 February 2015.

The Zenith drilling verified the past results that extended and improved the geological interpretation.

The MRE is interpreted and reported at a 0.5% copper equivalent (Cu-eq) cut-off suitable for open pit assessment.

The updated MRE for the Sulphide City – Scorpion – Window copper – zinc deposits at the 0.5% Cu-eq cut-off includes:

  • Indicated 2.2Mt @ 1.3% Cu, 1.3% Zn, 0.2g/t Au and 8g/t Ag
  • Inferred 2.7Mt @ 1.1% Cu, 1.4% Zn, 0.2g/t Au and 7g/t Ag
  • Total 4.9Mt @ 1.2% Cu, 1.4% Zn, 0.2g/t Au and 7g/t Ag

Zenith reports that in terms of the increases in tonnage and overall contained metal compared to 2015, the difference is attributed in part to a lower cut-off grade for reporting but is also the result of some resource extensions from recent Zenith drilling. In addition, it is attributed to a more robust interpretation that captures more or the mineralisation.

The estimate does not include the massive copper-zinc sulphide mineralisation identified at Snook and other prospects to the south, also within the Develin Creek project.

Commenting on the updated MRE Zenith Managing Director Michael Clifford said: “Mineralisation at the main Sulphide City lens remains open to the southwest.

“Multiple additional geological, geochemical, and geophysical targets remain to be tested”

Multiple additional geological, geochemical, and geophysical targets remain to be tested in both proximity to the deposit, as well as along strike in the extensive project landholdings.

There remains much to do on this project and our confidence in further discoveries remains high.”

The Develin Creek project contains a volcanic hosted massive sulphide (VHMS) copper-zinc deposit.

The MRE updated for Develin Creek includes the Sulphide City Scorpion and Window deposit and are located within the exploration licence  EPM 17604, 80km northwest of Rockhampton, Queensland.

Access to site is by means of an unsealed road via the town of Marlborough from the north or Glenroy from the south.

The deposit is located within EPM 17604 which is held by Mackerel Metals and was granted in 2008 until 2025. Mackerel Metals is a 100% subsidiary of Zenith.

The prospect is located within the Forrest Home Pastoral Lease and the tenement is in good standing with no known impediment to future grant of a mining lease.

EPM 17604 contains several other prospects and known mineralisation, mostly further to the south of Sulphide City.
