Rimfire Lachlan Fold Belt (LFB) Project Overview

==> picture [93 x 20] intentionally omitted <==

==> picture [310 x 326] intentionally omitted <==

Valley Project (Porphyry Cu-Au) - 100% RIM

• Located adjacent to Kincora/RareX Mordialloc and Trundle Park Cu/Au Porphyry projects. Situated on the interpreted western boundary of Caldera that has been split by ~30km wide Tullamore syncline with Northparkes (Cu/Au porphyry) on eastern boundary.

Cowal Project (Cu-Au) - 100% RIM

• Located east of Evolution’s Lake Cowal (Au) mine.

• On a major N-S structure that is parallel to Cowal gold mine controlling structure.

• • Prospective bedrock covered by circa 100m of younger sediments.

Fifield Project (Au-PGE) – RIM Managed Earn-in with GPR

• Earn-in with Golden Plains Resource for $4.5m to earn up to 50.1%.

• Rimfire costs for mine development “carried” with repayments from operating cashflow.

• Platina Lead (largest platinum (Pt) production source in Australia)

• Maiden JORC (2012) resource at Sorpresa of 125Koz gold + 7.9Moz silver .

• New significant intercept at Transit of 55m @ 0.94 g/t Au.

• GPR funding 4,000m of aircore and RC drilling at Transit to further evaluate discovery.

Avondale Project (Au-PGE) – RIM Managed Earn-in with GPR

• Northparkes Cu/Au (CMOC 80% / Sumitomo 20%)

• Cadia Au (Newcrest Mining, $20b Mkt Cap)

• Tomingley Au (Alkane Resources, $0.6b Mkt Cap)

==> picture [46 x 25] intentionally omitted <==

==> picture [35 x 22] intentionally omitted <==

==> picture [73 x 22] intentionally omitted <==

==> picture [57 x 20] intentionally omitted <==

❑ Numerous significant explorers including:

• Sunrise Energy Metals (Nickel, Cobalt, PGE’s*)

• Rimfire (Fifield Au Discovery, Historical Pt Mine, PGE’s*)

• Kincora Copper / RareX (porphyry Cu/Au)

• Alkane Resources (Au and porphyry Cu/Au)

• Emmerson Resources (Au and porphyry Cu/Au)

❑ Rimfire has circa 900 km[2] of ground in the area.

==> picture [343 x 305] intentionally omitted <==

• The six PGE metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum (Pt)

The Valley Project (100% RIM)

Location

• 15km east of Fifield Project, 35km west of the Northparkes porphyry copper-gold mine and adjacent to the Kincora Copper Mordiallic and Trundle Park Prospects.

==> picture [448 x 264] intentionally omitted <==

==> picture [93 x 20] intentionally omitted <==

Key Points

• Situated on western side of the interpreted caldera that is split by the Tullamore Syncline with Northparkes mine on the eastern side.

• 2021 drilling intersected at approximately 350m depth Ordovician bedrock beneath a broad zone of elevated surface copper geochemistry - the same type and age of rocks that hosts the Northparkes copper-gold mineralisation.

• Reprocessing of geophysical data confirms the Valley has a Northparkes scale footprint and potential to host a similar size copper / gold system.

• Northparkes mineralised system occurs as a smaller zone within a broader zone of elevated geochemistry which is the interpreted model for the Valley project.

Next Steps

• 60 aircore drillholes, total 1,500m

The Valley Project (100% RIM)

==> picture [440 x 281] intentionally omitted <==

Interpreted magnetic model of Ordovician rocks (in grey), which was tested by drilling and verified with Ordovician rocks occurring under younger sediment package at around 350m vertical depth.

The Cowal Project (100% RIM)

==> picture [93 x 20] intentionally omitted <==

Location

• 25 km east of Evolution Cowal Au mine and directly south of Porters Mount (historical sub-economic copper mineralisation).

• Neighbours include Newmont and Evolution.

Key Points

• Data analysis over past 12 months confirms concept that N-S structural trend extends south of Porters Mount and could host mineralisation under cover.

• The N-S structure also intersects major NW-SE structural corridor (Marsden Linear).

• The Cowal Mine lies on the same NW-SE structural trend and a parallel N-S trending structure.

Next Steps

==> picture [393 x 278] intentionally omitted <==

----- Start of picture text -----

2.2k
m
----- End of picture text -----

• 10 aircore drillholes, total 1,500m

Porters Mount corridor is intersected by Marsden Linear and on a N-S structure that is parallel to Cowal N-S structure.

9

Broken Hill Green View Project (100% RIM)

==> picture [93 x 20] intentionally omitted <==

==> picture [288 x 326] intentionally omitted <==

Location

• Rimfire’s tenure is located immediately along strike from Cobalt Blue’s significant Railway cobalt deposit (JORC Resource of 74Mt @ 704ppm CoEq, with 43,700t of inground cobalt – Source: COB ASX Company Presentation 10 June 2021 ).

• The project’s location will allow the Company to leverage its existing relationships, equipment, and people in the Lachlan Fold Belt area.

Key Points

• The addition of a wholly owned Cobalt project provides Rimfire exposure to a new commodity and an ongoing opportunity to support supply of this strategic metal for renewable energy.

• 25 blocks of Exploration Licence 5958 have been released from the Windy Ridge JV with Perilya and returned to Rimfire who will have a 100% interest and management control.

• 2 units remains in Windy Ridge JV managed by Perilya 90% interest (RIM 10% free carried) where focus remains on lead, zinc and silver potential.

10

Broken Hill Green View Project (100% RIM)

==> picture [93 x 20] intentionally omitted <==

==> picture [290 x 330] intentionally omitted <==

Key Points

• Rock units of interest that contain the JORC Resource at Railway extend along strike into Rimfire’s ground.

• Published geological maps show small patches of the prospective rock unit outcropping along strike and indicates continuity is likely under shallow cover.

• The underlying magnetic signature also suggests that the prospective stratigraphy extends into EL5958 before apparent folding towards to the SE. Outcrop extends at least 800m in EL5958 before dipping under recent cover.

• Cobalt mineralisation commonly exhibits an associated VTEM (Versatile Time Domain Electromagnetic) feature on the flank.

Next Steps

• Reconnaissance mapping

• Follow up aircore 2,000m drilling program (after completion of mapping)

Key Points

Key Points

• Recent work supports area of known historical anomalous platinum.
