Surface sampling on recently staked ground across the Blue Dick trends delivered a series of strong results, including 39.80g/t Au, 251g/t Ag, 4.65% Cu and 5.73% lead in one sample.
Silver grades reached as high as 1556g/t Ag, with several samples exceeding 1000g/t, and gold grades were up to 39.8g/t.
The program also served up a string of notable copper assays, including 22.38%, 23.47% and 8.34% Cu.
Mammoth Minerals (ASX:M79) also delivered strong outcomes for other metals, going as high as 12.44% zinc, 35.79% Pb and 0.45% antimony.
Channel sampling at Blue Dick also generated significant results, including 2.1m at 2.64g/t Au and 1.1m at 242g/t Ag and 0.19% Cu.
The company said these results showcased the significant growth potential of the Blue Dick trends, which lie adjacent to the project’s existing mineralised footprint along the Buster trend.
“The latest results continue to demonstrate the exceptional exploration upside across the broader Excelsior Springs project, with sampling identifying a parallel high-grade mineralised trend containing significant and consistently high-grade silver, copper, antimony, lead and zinc mineralisation – all of which are on the USA critical minerals list,” M79 managing director Glenn Poole said.
“Our strategy is to systematically explore, permit and drill test these newly identified high-grade targets to determine the scale and distribution of mineralisation.”
Mammoth also unveiled the latest drill results from a recently completed RC program along the Buster gold trend.
Results included 1.53m at 4.04g/t Au from 33.54m, 4.57m at 0.88g/t Au from 48.78m and 1.53m at 2.35g/t Au from 50.30m.
Management believes these outcomes continue to reinforce the scale potential of the 7km-long target corridor, with mineralisation remaining open along strike and down-dip.
“Importantly, the drilling to date has tested only around 1.3km of a total 7km mineralised corridor, highlighting the substantial remaining exploration upside across the project,” Poole said.
“With more than 21,000m of drilling completed to date, we are now moving towards the delivery of a maiden mineral resource estimate and exploration target in Q3 this year.”
The new results build on a growing list of historical and recent high-grade gold intercepts at Buster, including 51.8m at 4.0g/t Au from 39.6m, 14.4m at 4.33g/t from 117m and 33.5m at 5.35g/t from 41.2m.
