Rimfire Pacific Mining provided an exploration update for its Fifield and Avondale Projects, which are located 70 kilometres northwest of Parkes within the highly prospective Lachlan Orogen of central New South Wales (Figure 1). The intersection of a broad zone of strong gold (+/- silver and zinc) anomalism 1km east of the Sorpresa Gold Silver Deposit in an area of no previous drilling at Jack's Lookout (drillhole FI2401) has resulted in Rimfire's technical team developing a new geological model and targeting criteria for the formation of high-grade gold mineralisation throughout the Sorpresa area at Fifield. Drillhole FI2401 intersected 13m @ 0.12g/t gold from 226 metres, 5m @ 3.23g/t gold and 24g/t silver from 320 metres, and 61m @ 0.14g/t gold from 355 metres within a siliceous and sulphidic carbonaceous shale unit that is the same rock unit (the "Sorpresa Beds") that hosts the Sorpresa deposit (see Rimfire ASX Announcement dated 14 November 2022).

Sorpresa hosts a 2012 JORC Code compliant Total Combined Resource (1g/t gold and 85g/t silver cut off) of 1.519Mt @ 1.52g/t gold and 70g/t silver (74.3Koz gold and 3.44Moz silver) and remains open in all directions (see Rimfire ASX Announcement dated 6 November 2019). Detailed geological logging of diamond drill core from FI2401 has confirmed that the highest- grade gold mineralisation (i.e., 5m @ 3.23g/t gold and 24g/t silver from 320 metres) in the hole occurs at the intersection of the shallowly dipping Sorpresa Beds and a cross-cutting steeply dipping fault breccia. The fault breccia is interpreted to be a conduit for mineralising fluids to interact with the Sorpresa Beds (which represent a chemically favourable host rock) and form high grade gold + silver mineralisation.

As such the intersection of the two geological features represents a compelling exploration target and Rimfire's technical team is currently working to identify those areas where the target position might exist at shallow depths (Figure 3). The FI2401 high-grade drill intercept occurs within an area of no previous drilling so follow-up drilling is required to better understand the original intercept and to test the new targeting criteria.
