The company says the results from its most recent reverse circulation (RC) drilling program at Excelsior have intersected an interpreted high-grade “feeder” zone, with thick, shallow intercepts from surface.
Mammoth Minerals (ASX:M79) believes the drill bit has only scratched the surface at Buster so far, having only targeted the first 150m of depth. The prospect remains open both down-dip and along strike.
M79 managing director Glenn Poole said step-out drilling to the west had highlighted an expanding zone of mineralisation beyond previous drilling, providing confidence in the continuity of mineralisation as well as a fresh target for follow-up.
“Additionally, the deeper drill intercepts have confirmed the continuity of the orebody down-dip and are still open below 180m, with one of the deepest intercepts recorded to date across the prospect,” Poole said.
“The accelerated assay turnaround timeframes have allowed us to remain dynamic with our drill planning, with follow-up drilling already planned to follow up on these opportunities.”
The drill bit struck 13.72m at 1.15g/t gold from 62.5m in the hole 100m west of previous drilling, and 7.62m at 2.1g/t gold from 219.51m in the down-dip extension.
Apart from the ongoing drilling program at Excelsior’s Buster trend, Mammoth is also advancing drill permitting and ground exploration at the newly acquired Imperial project, and surface sampling and mapping programs at the Blue Dick prospect.
“Beyond the RC drilling at Buster, we are continuing to advance the targets at the newly-acquired Imperial Project with detailed mapping and further surface sampling to delineate the potential of the mineralised trends extending beyond the acquisition ground onto the newly staked claims,” Poole said.
“As two of the three Imperial targets are already drill advanced, drilling to further expand on these derisked areas will be a priority following the Buster RC campaign.”
M79’s Imperial targets produced results of up to 2.05m at 15.61g/t gold within 12.19m at 4.74g/t gold from 32m in historical drilling.
“The Blue Dick prospect is also advancing with surface sampling and mapping campaigns underway to delineate the extents of the parallel trends and linking structures of the gold and silver-rich polymetallic system to a drill-ready status later this year,” Poole said.
Looking ahead, Mammoth expects to field:
- Another batch of RC results from its drilling campaign at Buster;
- Assays from sampling at Blue Dick’s silver and gold-rich trends; and,
- Results from the underground mapping and sampling ongoing at the Imperial project.
With drilling and fieldwork advancing across the portfolio, Mammoth looks well positioned for further results.
