LiDAR Survey Identifies Compelling Gold
Target at Monkey Gully, Victoria

----- End of picture text -----

==> picture [121 x 22] intentionally omitted <==

• Infinity recently acquired LiDAR data over the Monkey Gully Gold Project, EL 7620, Victoria.

• A comprehensive LiDAR interpretation has revealed a total of 263 historical mine workings at Monkey Gully.

• The LiDAR interpretation has highlighted a dense cluster of historical mine workings around the Monkey Gully Prospect, which occurs around the margin of a Devonian intrusion.

• This target will be prioritised for further exploration, in the search for IntrusionRelated Gold Systems (IRGS).

• Monkey Gully lies ~40 km east of the Sunday Creek Gold Project, owned by Southern Cross Gold (ASX:SX2), which is host to significant (IRGS-style) gold mineralisation[1] . The geological setting of Monkey Gully has similarities to Sunday Creek.

Infinity Mining Limited (ASX:IMI) is pleased to announce the completion of a LiDAR interpretation at the Monkey Gully Gold Project, on EL 7620, eastern Victoria, which has identified a total of 263 historical mine workings.

Infinity Managing Director Joe Phillips commented:

“This new LiDAR dataset provides a better picture of the abundance of historical gold mining at Monkey Gully. The old mine workings are good indicators of the presence of metaliferous mineralisation, which our geologists will verify in the field in the coming months. Infinity’s strategy at Monkey Gully is to focus on areas of abundant historical workings, then apply modern exploration technologies to test for significant IRGS mineralisation at depth.”

Infinity’s Victorian Gold Strategy

The Monkey Gully Gold Project (EL 7620) is part of Infinity’s Victorian Gold portfolio, which includes four ELs in eastern Victoria, targeting Intrusion-Related Gold Systems (IRGS). All of Infinity’s ELs lie in proximity to Devonian intrusions within the Melbourne Zone (see Figure 1 ).

Monkey Gully EL 7620 was granted to Eastern Victoria Gold Exploration (EVGE) on 6 May 2025 for a period of 5 years. EVGE is a fully-owned subsidiary of Infinity.

Monkey Gully lies ~40 km east of the Sunday Creek Gold Project owned by Southern Cross Gold (ASX:SX2), which is host to significant high-grade gold mineralisation forming part of a major JORC (2012) Exploration Target of 1.7 to 2.6 Moz Au[2,3] . The geological setting of Monkey Gully has similarities to Sunday Creek, being proximal to Devonian intrusions within the Melbourne Zone, see Figure 1 .

Historical surface geochemical sampling and previous drilling by past explorers at Monkey Gully has returned anomalous metals (e.g. Sn, W, Mo, Au), consistent with IRGS pathfinder element geochemistry, enhancing the prospectivity of Monkey Gully (see IMI ASX Announcement 1 November 2024).

LiDAR survey

LiDAR specialists GeoCloud Analytics purchased the 2019 LiDAR dataset from ELVIS (facilitated by the VIC Government), totaling 28km[2] , in the SW part of EL 7620, see Figure 2 . The LiDAR ground point cloud data was reprocessed to yield a 50cm resolution bare earth Digital Terrain Model (DTM). Details of the survey are provided in the JORC Table 1, see Appendix 1 .

A number of new LiDAR images were generated by GeoCloud Analytics in order to identify surface features within the EL. The enhanced 3D datasets and 2D images have facilitated detailed interpretations, allowing the identification of geological structures, historical mine workings (adits and prospecting pits), land slips, access tracks and old drill pads.

How LiDAR Works

Light Detection and Ranging (LiDAR) is a remote sensing technique that uses laser pulses to measure distances and directions to objects. LiDAR systems can create 3D models of the earth’s surface (see Figure 3 ). A laser scanner fitted to an aircraft scans along its flight path, sending pulses out at a rate up to 1000khz, with multiple target reflections per pulse. While scanning, the GPS (GNSS receiver) on the aircraft is in constant communication the GPS satellite constellation, always knowing where it is in 3D space. During flight, the subtle aircraft movements are recorded, allowing post processing to correct these deviations ensuring the laser scan lines are calibrated and corrected for maximum precision and accuracy. The standout feature of LiDAR is its ability to see the ground through trees and heavy vegetation.

LiDAR Interpretation

GeoCloud Analytics completed a detailed interpretation of the LiDAR data at Monkey Gully, accurately documenting the extent of historical mining activity across the survey area. The interpretation of the LiDAR data has indicated a total of 264 historical mine workings, including 21 adits and 242 other prospecting pits within the survey area (see Figure 4 ). The old workings defined across Monkey Gully are much more abundant that previous thought, highlighting a high-priority target for Infinity to follow up. The LiDAR interpretation has also identified structural trends which are likely pathways for gold mineralising fluids (see Figure 4 ).

Monkey Gully Prospect Target

Around 50% of the 262 historical mine workings are clustered around the old Monkey Gully Prospect (see Figure 5 ). The high abundance of old adits plus other significant workings around this prospect is a strong indicator of the presence of gold and base metals mineralisation, as significant mining effort was invested in this small area by the “old miners”.

Many of the old workings lie on the margin of the Devonian granitoid intrusion (Black Range Granodiorite), adjacent to the NW-trending Wilson Creek Shale (see Figure 5 ). This favourable geological setting, combined with multi-element geochemical anomalism identified in historical geochemical / drilling datasets, supports strong prospectivity for IRGS at Monkey Gully. This target area will be followed-up by Infinity’s exploration team in the coming months.

Next Steps

A thorough review of the historical geochemical data and previous drilling, including 3D modelling of historical drill holes will be completed in the short term. Monkey Gully Prospect will be followed up in the field with geological mapping and further geochemical sampling, in order to identify the most prospective target zones. Geophysical surveys and drilling will then be implemented to test for IRGS mineralisation at depth.

Criteria	JORC Code explanation	Commentary
	• The assumptions used for any reporting of metal equivalent values should be clearly stated.
Relationship between mineralisation widths and intercept lengths	• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true _width not known’). _	• Not applicable.

Balanced reporting	• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	• Not applicable.
Other substantive exploration data	• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	• The results were integrated into a GIS framework with Seamless Geology, regional structure, and drainage overlays to identify spatial associations with prospective granodiorite contacts, hornfels aureoles, and mapped IRGS-style features.
