Orange Minerals (ASX:OMX) identifies multiple conductive anomalies at Lennon’s Find

Orange Minerals has taken another step in that direction at its Lennon’s Find Project, with a downhole electro magnetic survey identifying several conductive anomalies associated with a recently completed diamond drill hole.

The results provide new vectors for follow up exploration in an area that has a history of base metal mineralisation and prior small scale mining.

Highlights

• Downhole electro magnetic survey of diamond drill hole OLFD001 at Lennon’s Find identifies 3 conductive anomalies.
• Drill hole OLFD001 reached a depth of 615 m and targeted a deep copper gold induced polarisation anomaly interpreted as a possible volcanic massive sulphide system.
• One broad strongly conductive off hole anomaly detected at approximately 150 m downhole with a modelled extent of approximately 50 m x 10 m.
• A second moderately conductive anomaly identified between 380 m and 400 m with an estimated extent of approximately 50 m x 50 m.
• A distinct in hole response detected at 480 m downhole associated with a modelled conductive body measuring approximately 195 m x 95 m.
• Assay results from drill hole OLFD001 are expected shortly.

The Lennon’s Find Project is located approximately 70 km south of Marble Bar in Western Australia and sits within the eastern section of the Archean Pilbara Craton.

The project area covers the contact between the Mount Edgar Batholith and volcanic sequences of the Warrawoona Group, a geological setting known to host base metal mineralisation including sphalerite, chalcopyrite and galena.

Orange Minerals drilled the HQ diamond hole OLFD001 in December to test a coincidental geochemical and induced polarisation anomaly interpreted as a potential volcanic massive sulphide target at depth beneath an established zinc lead silver system.

The hole passed through Apex Basalt before intersecting the Duffer Formation, where the main Lennon’s Find mineralisation occurs near the top of the formation.

Following completion of drilling, the hole was cased and surveyed using downhole electro magnetic methods, a technique commonly used to detect conductive bodies that may represent accumulations of sulphide minerals.

The survey identified three separate conductive sources associated with the drill hole.

The first anomaly occurs at approximately 150 m downhole and represents a strongly conductive off hole source centred below and to the north east of the drill hole, aligning with sulphides including pyrite, pyrrhotite and magnetite identified in the drill core at around 146 m.

Modelling indicates a conductive body with an approximate areal extent of 50 m x 10 m.

A second anomaly was detected between 380 m and 400 m downhole and is described as moderately conductive. The modelled body extends roughly 50 m by 50 m and coincides with quartz carbonate magnetite veining within the Apex Basalt sequence.

The third response was recorded at around 480 m downhole, representing an in hole conductive feature with modelling indicating a weakly conductive body measuring approximately 195 m x 95 m that correlates with the main Lennon’s Find mineralisation intersected between 510 m and 526.6 m.

The relatively low conductivity is considered consistent with zinc rich mineralisation such as sphalerite, which typically exhibits weaker conductive properties than copper bearing sulphides.

Managing Director Chris Michael noted that the geophysical results add to the geological understanding of the system and provide direction for future drilling.

“Completion of the DHEM survey marks another important step in advancing our understanding of the Lennon’s Find Project’s geological architecture and mineralisation controls. The identification of multiple conductive anomalies associated with the drillhole supports the compelling VMS prospectivity of the area and provides valuable vectors for follow-up drilling. We look forward to receiving the assay results from OLFD001 and integrating these with the geophysical data to guide the next phase of exploration at the project.”

For Orange Minerals the immediate focus shifts to the pending analytical results from OLFD001, which will be integrated with the geophysical data to refine exploration targeting.

The company also plans high resolution drone based magnetic and LiDAR surveys across the Lennon’s Find mineralised trend to support improved geological and structural interpretation ahead of additional drilling.

In a district with a documented exploration history and established base metal occurrences, the combination of drilling, geophysics and detailed structural interpretation will determine whether Lennon’s Find evolves from a known mineralised system into a broader exploration opportunity within the Pilbara polymetallic landscape.
