Fifield Exploration Drilling Update

Highlights

• ✓ Results from the Southern Area Phase 2 aircore drilling and bedrock sampling support the interpretation that the bedrock has an Ordovician Macquarie Arc geochemical signature. However, testing indicates that it is likely to be from Stage II volcanism rather than the Stage III and IV volcanism associated with mineralisation at Cowal (gold) and Northparkes (copper / gold).

• ✓ Northern Area Phase 1 aircore drilling indicates a peak copper anomaly value of 703ppm copper.

• ✓ The focus of Phase 3 Drilling Program will be the

• a) Northern Gold prospect which is an area with a surface footprint of 400m x 100m of historical gold workings that was partially tested with the Phase 1 drilling program, and

• b) Transit prospect where in 2017 Rimfire obtained promising intersections from RC hole Fi0808 (60 degrees inclined hole) of 20m @ 1.11g/t Au from 48m depth.

Rimfire Pacific Mining NL (“Rimfire”, “Company”; ASX Code “RIM”) advises that assays for the second phase of the drilling program for Southern Area have been received. These results provide further support that the Rimfire interpretation of these rocks as part of the Ordovician Macquarie Arc rather than younger Silurian or Devonian rocks is valid. However, based on scandium (Sc) versus zirconium (Zr) ratios, the area appears to be associated with Phase II volcanism rather than the Phase III and IV volcanism that is interpreted as being responsible for the nearby significant gold, and copper / gold mineralised systems of Cowal (Evolution Mining) and Northparkes (CMOC) respectively.

Phase 3 operational planning is in progress for the Northern Gold and Transit prospects including work to obtain the necessary NSW Government drilling approvals and local landholder access agreements. The Coronavirus will influence the scheduling of company activities in the short term.

Northern Gold

The Northern Gold prospect is 2km north of Sorpresa and drilling was designed to test the bedrock beneath a +400m long x 80m wide zone of historical mine pits (Figure 1). The Phase 1 RC drilling at the Northern Gold prospect consisted of 2 holes totaling 165.5m. The drilling generated anomalous gold (0.15 ppm), copper (0.17 %), lead (120 ppm) and zinc (0.13%) (ASX Announcement: Fifield Exploration Update 5Nov2019) although it did not intersect high copper or gold grades. These results are supportive of the IRGS model for mineralisation in the area (ASX Announcement: Sorpresa Basin IRGS Model 15July2019). The surface gold remains unexplained by the limited drilling to date and an aircore drilling program is the next step in understanding and locating the source of historical gold from this prospect. The size of the known footprint of Northern Gold historical gold workings supports the potential for a significant mineralised system, which could be either an independent mining operation or an incremental additional source of supply feed to any Sorpresa development.

Transit Prospect

The Transit prospect is located 3km to the east of Sorpresa and sits at the interpreted intersection of a north-northeast trending low angle thrust and a northwest trending structural corridor thought to be representative of the Lachlan Transverse Zone (Figure 2). The geology of the area consists of a series of highly deformed, quartz veined carbonaceous sediments and minor andesitic composition volcanics and volcanoclastics. In 2017 Rimfire obtained an

intersection at Transit of 20m @ 1.11g/t Au from 48m depth (ASX Announcement: Transit Area 44m at 0.61g/t Gold and Potential for Porphyry 19Sept2017). The focus of the next phase of work at Transit will be to better understand the geological structural setting that is thought to control zones of mineralisation and to test initially for further zones - of shallow higher grade mineralisation that may support Rimfire’s Dual Strategy (ASX Announcement: Dual Strategy Sorpresa Appraisal and Regional Discovery 25Sept2018) of monetisation of Sorpresa.

Ordovician Macquarie Arc Characterisation Study

A component of the Phase 1 and Phase 2 drilling programs in the Southern Area was to obtain bedrock samples for geochemical analysis to determine if the rocks have a similar geochemistry to the Ordovician Macquarie Arc volcanism. This is significant as historically the rocks in the Southern and Northern Areas have been considered younger Silurian / Devonian age rocks and consequently considered less prospective terrane for discovery of major copper / gold or gold mineralised systems. The older Ordovician Macquarie Arc age rocks host nearby major copper / gold and gold mineralised systems including Northparkes (CMOC) and Cowal (Evolution Mining) respectively.

Eight aircore or grab samples of either andesite lavas, associated volcaniclastic rocks or diorite from the Southern Area have been assayed for a suite of 48 elements by ALS (Australian Laboratory Services) (Figure 3).

A preliminary study of the data supports Rimfire’s interpretation that the rocks are primarily intermediate in composition and are part of the Ordovician Macquarie Arc. All but one sample plots within or near the Mid to Late Ordovician Goonumbla Volcanic field on a Zirconium (Zr) versus Scandium (Sc) diagram (Figure 4). There are four identified volcanic events recognized within the Macquarie Arc volcanic sequence and they are defined as Phases I to IV. The most significant phases are the Stage III and IV events that are associated with mineralisation events at the Northparkes and Cowal mines respectively. The Stage II (Goonumbla) is not considered to be associated with significant large scale Northparkes or Cowal style mineralisation. The outlier is a quartz diorite (Fi1980) from within a geological feature referred to as the Murrambogie Dome that may be part of the same Ordovician ultramafic event which hosts the Syerston cobalt nickel deposit.

Southern Area

A total of 36 reconnaissance aircore holes totaling 1,423 metres were drilled in the Phase 1 (ASX Announcement: Fifield Exploration Update) and Phase 2 programs in the Southern Area (Figure 5, Table 1 and 2). The broad spaced drilling program was aimed at evaluating the Southern Area’s potential to host large tonnage Lake Cowal or Northparkes style deposits. As expected, interpreted Ordovician intermediate lithologies were intersected in all holes with more proximal lavas located in the eastern third of the area.

The copper geochemistry for the region is generally subdued with all three metre samples assaying < 254ppm. Gold is also subdued assaying <0.3ppm. The only exception is a three metre interval of quartz diorite from the centre of the Murrambogie Dome, which assayed 0.29 ppm gold.

The optimal strategy for further work in this area is in development.

Northern Area

During the Phase 1 drilling program eleven aircore holes, totaling 408 metres, were drilled in September 2019 (ASX Announcement: Fifield Exploration Update). Three holes were intended to confirm the presence and obtain samples from the northern end of a 2.5km long by 800m maximum width anomaly defined by greater than 400ppm copper geochemistry identified by previous explorers. Six holes tested possible extensions to the north and east. While two holes were designed to locate the source of a 2.72% Copper assay from a grab sample located 900metres to the east of the main anomaly (Figure 6 and Table 3).

Rimfire Pacific Mining NL | ABN 59 006 911 744 | ASX: RIM

ASX Announcement 26[th] March 2020 Page 3

==> picture [97 x 21] intentionally omitted <==

Diorite assaying up to 703ppm copper was intersected within the copper anomaly identified by previous explorers. This feature is interpreted as being marginal to a zone of anomalous copper in volcaniclastic rocks which are sometimes intruded by diorite dykes assaying less than 400ppm copper.

Rimfire and previous explorers drill holes were terminated at refusal immediately above the base of oxidation. Rimfire’s drilling indicates that the 2.5km long copper anomaly is related to a line of discrete moderately copper anomalous (400 to 700ppm copper) diorite plugs. Minor secondary enrichment has resulted in occasional assays exceeding 1000ppm copper at several locations.

The two holes designed to locate the source of the 2.72% copper grab sample intersected un-mineralised Devonian sandstone.

The optimal strategy for further work in this area is in development.

Rimfire Managing Director Craig Riley states:

The results from the Phase 1 and Phase 2 drilling programs over the Northern and Southern Areas support the Rimfire interpretation that the basement rocks are older Ordovician rocks that also host the nearby significant Northparkes (copper / gold) and Cowal (gold) mines.

The focus of work for Phase 3 drilling will now transition to the Northern Gold and Transit prospects which both retain strong potential for economic gold mineralisation that could be independent significant discoveries or be accretive projects to any development of the Sorpresa Resource

Table 4: JORC Code Reporting Criteria

Section 1 Sampling Techniques and Data – Surface Rock Samples, Auger and Aircore Drilling

Criteria	JORC Code explanation	Commentary
Sampling techniques	Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.	Aircore sampling Each sample represents a scooped composite sample of cuttings generated via aircore drilling. Cuttings are collected in buckets from the cyclone for each metre drilled then tipped on a plastic sheet. A PVC spear is used to collect a sample from each pile of cuttings with three consecutive metres combined in a single calico sample bag. The nature of the sample generation and collection process means the samples should be considered as indicative of grade rather than representative of a precise grade.
	Include reference to measures taken to ensure sample representativity and the appropriate calibration of any measurement tools or systems used.	Blank sample and reference standards were inserted into the sample sequence.
	Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.	Industry standard preparation, including full sample pulverising prior to subsampling for assay, was undertaken for samples up to 3.6kg. For samples over 3.6kg the sample was split in the laboratory to generate as sample prior to pulverising. The field collected samples were typically in the order of 2 to 4kg, average 2.8kg. 50 g of pulverized sample was utilized for gold determination via Fire assay, and a smaller sub-sample utilised for multi-element assay via Four Acid Digestion with ICP-MS Finish.
Drilling techniques	Drill type (e.g. core, reverse circulation, open‐ hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face‐sampling bit or other type, whether core is oriented and if so, by what method, etc.).	Aircore drilling was completed utilising a small 4WD mounted aircore drill rig utilising an aircore drill bit with an auxiliary trailer mounted air compressor.
Drill sample recovery	Method of recording and assessing core and chip sample recoveries and results assessed.	A visual comparison of sample size was made as drilling progressed. Observations were recorded by the sampler.
	Measures taken to maximise sample recovery and ensure representative nature of the samples.	Any noted variability was discussed with the driller with an aim to ensure consistency.
	Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.	No relationship evident in current data.

and sample preparation	For all sample types, the nature, quality and appropriateness of the sample preparation technique.	Sample preparation followed industry standard practice and is considered appropriate (refer to sampling techniques section above).
	Quality control procedures adopted for all sub‐ sampling stages to maximise representivity of samples.	All sampling equipment was cleaned between samples.
	Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling.	Field duplicates, blanks and standards were inserted in the sample stream submitted to the commercial laboratory. No issues have been identified.
	Whether sample sizes are appropriate to the grain size of the material being sampled.	Sample sizes are considered suitable for a qualitative assessment for indications of mineralisation.
Quality of assay data and laboratory tests	The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
