Dart Mining NL announced that rock samples collected across the Granite Flat project demonstrate strong support for recent soil sampling and drilling results across the project. Rock chip and grab samples demonstrate that Cu-Au ± Ag, Zn, Pb mineralisation is coincident with the soil Cu anomalies identified in Dart Mining's recent regional sampling program. A total of 98 chip samples have been collected across the Granite Flat project to assess and characterise the mineralisation style of the project.

This sampling program has yielded some rewarding results, with notable Cu, Au, and Ag ± Pb and Zn mineralisation occurring in association with soil Cu and Au anomalies (reported in DTM ASX 4 August 2022). Of the 98 samples collected, 72 samples have returned anomalous values for either Cu, Au, Ag, Pb, or Zn. The lithology of samples varies broadly from aplitic dykes, laminated quartz, quartz breccia, granitic porphyry and altered granodiorite rock.

The diversity of the mineralisation and alteration styles encountered in this surface rock sampling program also speaks to the geological complexity of this project. Fortunately, the geological mapping, geophysics, soil surveys, and drilling completed by Dart Mining over the past 18 months is working towards unravelling the story of this complex project. Due to the limited nature of outcrop available at Granite Flat, many these samples are spot (grab) samples of either float material or from mullock dumps adjacent to historic workings.

The majority of these historic workings have targeted narrow, high-grade gold and copper mineralisation on discrete structures which are well resolved in LiDAR imagery, and in surface mapping. Additionally, mineralisation also appears to be associated with fine-grained aplitic dykes across the project area; and, in the case of the smaller As-Pb soil anomalies, rock samples are dominantly gossanous in nature.
