North Stawell Minerals Limited announced high grade, plunging shoot at Darlington. A seven-hole air core drilling program has identified a high grade, south-east plunging shoot at the Historic Darlington Mine, 10km north of Stawell. Highlights: The well-defined gold mineralisation at Darlington includes: 3m at 11.0 g/t Au from 60m (NSAC0527) Includes 1m at 17.7 g/t Au from 62m; 6m at 3.45 g/t Au from 42m (NSAC0532); 3m at 2.20 g/t Au from 45m (NSAC0530).

All drillholes returned significant grades and 5 of the holes end in anomalous mineralisation (>1 g/t). The historic Darlington mine produced 2,347 oz Au at 18.2 g/t Au, and is the southernmost mineralisation in the highly gold-prospective eastern Stawell Corridor, which also hosts the mineralisation at Stawell (4.9Moz Au), Wonga Mine (294koz Au) and Wildwood Inferred Mineral Resource (55koz Au). The Darlington trend is 700m in length, trending northwest-southeast, and open in both directions.

The high-grade shoot lies within this plane, and plunges moderately to the southeast - and is untested and open down-plunge. Other historic intercepts at Darlington may represent additional, parallel, structurally controlled mineralised structures. Darlington Update: The Darlington mine is the southernmost target on the 10km long Germania-Darlington gold trend.

The prospect occurs in the eastern Stawell Corridor, a 5km wide structural zone defined by the Stawell Fault to the west and the Coongee Fault to the east. The eastern Stawell Corridor include the Stawell Gold Field (4.9Moz Au), Wonga Mine (294koz Au) and Wildwood Inferred Mineral Resource (55koz Au). The Darlington Prospect is one of 6 prospects along the Germania-Darlington trend.

Historic mining at Darlington records 2,347 oz @18.2 g/t Au. Historic drilling along strike of the mine has identified a 700m gold anomalous trend with a 150m zone of higher-grade intercepts centred on the mine. The Darlington mineralisation remains open along strike and at depth, and the new results are open down-plunge beneath historic drilling.

The central area of the Darlington Prospect occurs within the Darlington Mine Reserve. NSM established access to this area in February 2023, and drilled the target in early March. Seven priority holes were completed for a total of 575m.

Three of seven drill holes returned significant mineralisation (1+ g/t Au, Table 1). All seven drillholes returned anomalous gold grades (>0.05 g/t Au and <1 g/t Au). NSM Air core drilling results include: 3m at 11.0 g/t Au from 60m (NSAC0527); 6m at 3.45 g/t Au from 42m (NSAC0532); 3m at 2.20 g/t Au from 45m (NSAC0530).

The assays expand on historic results: 3m at 2.83 g/t Au from 42m (SEXR1314); 0.85m at 5.65 g/t Au from 201.2m (DAD001); 1m at 3.15 g/t Au from 57m (SEXR1319). Five of seven holes drilled end in anomalous grades, warranting follow-up: 18m at 0.18 g/t Au from 80m* (NSAC0526); 17m at 2.12 g/t Au from 60m* (NSAC0527); 8m at 0.17 g/t Au from 63m* (NSAC0529); 41m at 0.43 g/t Au from 36m* (NSAC0530); 2m at 0.27 g/t Au from 60m* (NSAC0531). The drilling tested for continuity of mineralisation identified in an historic vertical AC hole(SEXR1314) with focus on determining possible plunge orientations for the mineralisation.

Results indicate a southeast plunging shoot within the interpreted mineralisation plane that has encouraging gold grades (3-17.5 g/t Au) and significant intercept widths (3-6m) and remains open down-plunge. The (re)interpretation also highlights the potential for repeat, parallel shoots at depth with similar, structurally controlled orientation. Gold mineralisation is observed in drill chips and historic mine waste, and includes weakly laminated quartz veining with strong ferroan carbonate alteration ± pyrite ± arsenopyrite as well as hydrothermal, silicified breccias and associated stockwork veining.

Similar alteration and mineralisation is observed in the resampling of historic hole DAD001 (100m down-dip and a likely parallel structure) which returned 0.85m at 5.65 g/t Au from 201.2m. DAD001 was drilled to test for down-dip mineralisation at Darlington and did not effectively test the plunge determined by this drilling campaign (DAD001 drilled underneath the projected target).
