New Murchison Gold has recorded its highest-grade 1m reverse circulation (RC) sample ever at its Garden Gully Gold Project in Western Australia, with drilling at the Crown Prince open pit returning 2,860 grams per tonne (g/t) gold.
The standout result came from hole CPRC030, which also intersected 14m at 231.67g/t gold, including 4m at 805.2g/t. The intersection sits beneath the Crown Prince open-pit shell, outside the current mineral resource interpretation and close to the proposed underground mine design.
The 1m sample initially returned 2,620g/t gold, with a repeat assay returning 3,100g/t with the company reporting the average of the two results.
New Murchison chief executive officer Alex Passmore said the results highlighted the potential for further resource growth as the company evaluates an underground opportunity.
“We are very pleased with this exceptional high-grade result from our recent near mine extensional drilling at Crown Prince,” Alex Passmore said
“CPRC030 has returned the highest-grade RC sample we have recorded at Garden Gully, and 14 metres at over 200g/t gold. Together with CPRC008 and our earlier SEZ results, the case for a Crown Prince underground continues to build.”
Further high-grade results came from surface hole CPRC008, about 125m west of CPRC030. The hole intersected 3m at 14.9g/t gold from 181m and 4m at 13.5g/t from 192m, about 120m vertically above a previously reported intersection of 3.2m at 48.9g/t gold.
Assays are pending for five nearby holes, including CPRC009A, CPRC026, CPRC034, CPRC037 and CPRC038.
Crown Prince’s existing underground mineral resource estimate stands at 1.45 million tonnes at 3.2g/t gold for 150,400 ounces, using a 1.2g/t cut-off grade.
New Murchison plans to drill a diamond twin of CPRC030 to confirm the intersection’s width and grade and obtain oriented core to help determine the high-grade shoot’s orientation and plunge. Step-out diamond and RC drilling is also planned around CPRC030 and CPRC008.
The company said the orientation, plunge and continuity of the CPRC030 high-grade shoot remain unknown. Further drilling will help determine its extent and inform ongoing resource evaluation and underground studies.
