Highlights

  • Within that, 4 m averaged 805.2 g/t, including 1 m at 2,860 g/t from 82 m.
  • The business states the intercept lies about 118 m below natural surface and outside the current Crown Prince Mineral Resource.
  • NMG suggests a vertically extensive quartz vein and shear system, which it plans to test further.
  • New Murchison Gold (ASX:NMG) has reported results from its reverse circulation (RC) drilling at the Crown Prince.

New Murchison Gold (ASX:NMG) has reported results from its reverse circulation (RC) drilling at the Crown Prince deposit within the Garden Gully project in Western Australia, including a short interval of very high grade gold in one in-pit hole and deeper intercepts in a surface hole.

The Headline Intercept

Hole CPRC030, drilled from an in-pit pad, returned 14 m at 231.67 g/t gold from 80 m depth, using a 0.5 g/t cut-off. Within that, 4 m averaged 805.2 g/t, including 1 m at 2,860 g/t from 82 m. The 2,860 g/t figure is the average of an original assay of 2,620 g/t and a laboratory repeat of 3,100 g/t. Visible gold was seen in the RC chips, and the company describes the 1 m sample as the highest-grade metre of RC drilling in its Garden Gully database.

The business states the intercept lies about 118 m below natural surface and outside the current Crown Prince Mineral Resource. It interprets the result as a discrete quartz vein shoot whose orientation, plunge and continuity are not yet known. Other holes from the same pad did not return comparable grades, and earlier drilling 20 to 25 m away is referenced. Coarse-gold results of this kind are difficult to predict from wide-spaced drilling and are usually top-cut in resource estimation, the company notes.

Surface Hole Cprc008

On the western side of the main and north open-pit areas, CPRC008 returned 3 m at 14.89 g/t from 181 m and 4 m at 13.54 g/t from 192 m, with narrower higher-grade sections including 1 m at 36.0 g/t. These sit about 160 m below natural surface and about 120 m above an earlier diamond intercept of 3.2 m at 48.9 g/t reported in April 2026. NMG suggests a vertically extensive quartz vein and shear system, which it plans to test further.

The Program And What Is Outstanding

The 18-hole, 3,091 m program comprises seven surface holes and eleven in-pit holes. Assays have been received for 12 holes; five remain pending (CPRC009A, CPRC026, CPRC034, CPRC037 and CPRC038), and one hole was abandoned for excess deviation and redrilled. Other reported intercepts were modest, for example 1 m at 2.78 g/t in CPRC033, and several holes had no significant results. Gold was assayed by fire assay at Bureau Veritas in Kalgoorlie.

Underground Context

Crown Prince's Mineral Resource, reported on 23 September 2026 at a 1.2 g/t cut-off, totals 1.453 million tonnes at 3.2 g/t for 150,400 ounces (measured, indicated and inferred combined). The company is investigating an initial portal about 75 m below the pit surface, and says the new intercepts sit roughly 43 m (CPRC030) and 85 to 95 m (CPRC008) below that elevation. A shared decline could potentially reach several high-grade shoots about 200 m apart. Mining method, dilution and recovery remain unassessed, and the company states there is no assurance that further exploration will lead to a Mineral Resource or that underground development will proceed.

Data Points To Note

The release contains some internal inconsistencies, including differing descriptions of internal dilution, two CPRC008 intercepts described in the text but missing from one table, and a stated distance between CPRC030 and CPRC008 that does not match the collar coordinates. Readers should compare the figures with the full announcement and its appendices.

Next Steps

The company lists a diamond twin of CPRC030 to confirm width and grade and obtain oriented core; step-out diamond and RC drilling around CPRC030 and CPRC008, alongside geotechnical holes for the proposed portal and decline; screen fire or bulk assaying of high-grade intervals; incorporation of results into resource models and underground studies; and receipt of the pending assays. The release does not give dates for these steps.
