Orange Minerals (ASX:OMX) extends Lennon’s Find mineralisation with deep drill results

Orange Minerals has reported results from its first deep diamond drill hole at the Lennon’s Find Project in the Pilbara, with the program confirming the continuation of volcanic massive sulphide (VMS) style mineralisation at depth and significantly improving the Company’s geological understanding of the system.

The hole was designed as a step-out test of coincident geophysical and geochemical anomalies approximately 380m down-dip of known mineralisation.

Highlights

• VMS-style mineralisation intersected at depth, extending the known system approximately 675m down dip
• Broad anomalous polymetallic interval (10.6m) intersected from 516m, including zones of elevated Zn–Pb–Ag mineralisation
• Intercept includes 5m at 0.04g/t Au, 56g/t Ag, 0.03% Cu, 0.59% Pb and 1.58% Zn
• Stratigraphic position of mineralisation confirmed, consistent with the established Lennon’s Find model
• Downhole EM identified multiple conductive responses, providing vectors for follow-up targeting
• Drill hole delivered under EIS co-funding

The diamond drill hole OLFD001 tested an Au–Ag–Pb–Zn IP anomaly interpreted to represent VMS-style mineralisation at depth below zinc-barite anomalous gossans.

The hole was collared in the Apex Basalt and continued to the base contact at 500.1m before passing into felsic schist and cherts of the Duffer Formation.

The Lennon’s Find mineralisation was identified at the top of the Duffer Formation, approximately 16m below the base of the basalt, with an anomalous silver and base metal zone over 10.6m intersected between 516m and 526.6m, containing sphalerite, galena, pyrite and chalcopyrite identified in the core.

The zone was reported as consistent with the stratigraphic position of mineralisation near surface and has successfully extended the mineralisation 675m down dip.

The cause of the IP anomaly was not identified in the hole and further work is required to understand the geophysical anomaly.

Downhole electromagnetic surveying identified three conductive anomalies, including a strongly conductive off-hole anomaly at 150m downhole with a modelled areal extent of approximately 50m x 10m.

A moderately conductive off-hole anomaly was identified between 380m and 400m with an areal extent of approximately 50m x 50m.

A distinct in-hole response was observed at 480m downhole, with modelling indicating a conductive body with an areal extent of 195m x 95m that correlates with the main mineralisation intersected between 510m and 526.6m.

Orange Minerals Managing Director Chris Michael said:

“This first deep step-out hole represents an important technical milestone for Lennon’s Find. While the primary geophysical target was not directly intersected, the program has confirmed the continuation of the VMS system at depth and significantly improved our understanding of the geological architecture. Importantly, the DHEM survey has identified multiple conductive targets that provide clear vectors for follow-up work. These results will underpin the next phase of exploration as we refine our targeting toward thicker and higher-grade zones within the system.”

The Company has satisfied both milestones of the earn-in agreement with Musketeer Mining Ltd, resulting in a 75% interest in M45/368 with standard dilution clauses for future exploration, and is undertaking further geophysical review to refine drilling targets and exploration activities at Lennon’s Find.
