Zenith Minerals and Rumble Resources expand known zinc-lead mineralisation at Earaheedy
Rumble and Zenith’s latest drilling results indicate multiple extensional faults underlying the currently defined mineralisation at the Chinook prospect.
Drilling at Zenith Minerals’ (ASX: ZNC) Earaheedy zinc-lead-manganese-silver joint venture has continued to increase known mineralisation at the Chinook discovery.
Latest results have delivered a 44% increase in the size of Chinook’s mineralised footprint within the project.
Chinook’s mineralised footprint is now 4.1km by 1.9km and remains open in all directions.
Zenith chief executive officer Michael Clifford said expanding the Chinook mineralised footprint further was a “great achievement”, particularly with the higher-grade zinc-lead zones holding together as drill density increases.
The company has a 25% free carried interest in Earaheedy to a bankable feasibility study, with Rumble Resources (ASX: RTR) owning the majority 75% stake.
High-grade hits
Zenith and Rumble have received and compiled results from 51 reverse circulation holes for 7,826m and two sonic holes at Chinook.
Latest assays have returned further high-grade zinc and lead hits at the prospect.
Notable results were 15m at 4.02% zinc and lead, and 4.86 grams per tonne silver; 11m at 3.92% zinc and lead, and 4.23g/t silver; and 8m at 5.2% zinc and lead, and 9.57g/t silver.
Mr Clifford noted the results from the first two holes in the sonic twin hole program alleviated any concerns of the companies’ RC drill methodology.
These holes confirmed the high-grade zinc-lead intersected in RC drilling with assays of 19m at 6.1% zinc and lead.
Advancing Earaheedy joint venture
The assays are part of the recently expanding drilling program at Earaheedy with 40,000m now to be completed.
Drilling is also underway at the Magazine and Navajoh zinc-lead prospects which are about 7km to 12km southeast of Chinook.
Mr Clifford said Rumble was “particularly excited” about these new prospects and he looked forward to reporting the assays as soon as they were at hand.
As well as the Earaheedy joint venture, Zenith has pegged up 100km of prospective zinc-lead land in the region.
