Rimfire Pacific Mining (ASX: RIM, “Rimfire” or “the Company”) is pleased to advise that the first two diamond drill holes completed as part of a larger 6 hole (~1,000 metre) step out drilling program at the Bald Hill Cobalt Copper Prospect, have successfully intersected multiple broad zones (downhole widths) of sulphide mineralisation 100 – 200m away from previous high-grade cobalt drill intercepts.
Highlights
- The first two holes in the current diamond drilling campaign have intersected multiple broad zones (downhole widths) of sulphide mineralisation 100 – 200m away from previous high-grade cobalt drill intercepts;
- FI2612 intersected disseminated and banded sulphides (pyrite) between 70 and 110m, and semi-massive sulphides (pyrrhotite) between 110 and 129m
- FI2613 intersected disseminated and banded sulphides (pyrite) between 67 and 105m, disseminated and fracture – fill sulphides (pyrite) between 105 and 128.5m and brecciated semi – massive sulphides (pyrrhotite) between 151.9 and 185.1m
- The sulphides intersected in the current drillholes are visually similar to the high-grade mineralised intercepts obtained in Rimfire’s previous drilling at Bald Hill with assay results required for confirmation
- First assay results expected within 6 to 8 weeks as the 6-hole diamond drilling program continues
Commenting on the announcement, Rimfire’s Managing Director Mr David Hutton said: “The Bald Hill prospect continues to grow with broad zones of great - looking sulphides intersected in the latest step out holes.
The diamond drilling is helping our geologists build a detailed model for the prospect and we look forward to seeing what the rest of the program delivers.
Drilling, geological logging, and sampling is continuing, with first assays expected in 6 to 8 weeks’ time and Rimfire looks forward to providing further updates as new information comes to hand.”

High grade Massive Sulphide Intercepts Confirmed at Oval
HIGHLIGHTS:
- OVD027 confirms the continution of high grade massive sulphide from OVD0211 with an intercept of 6.1 metres of 4.16% Cu, 3.51% Ni, 0.G3g/t E3, and 0.13% Co from G8.2 metres encountered between broader high grade zones of:
- A dense disseminated intercept - 26.2 metres of 0.44% Cu, 0.52% Ni, 0.12g/t E3, and 0.03% Co from 72.0 metres and
- A net textured intercept - 15.3 metres of 1.15% Cu, 0.79% Ni, 0.35g/t E3, and 0.04% Co from 104.3 metres;
- A high grade broad intersection is confirmed at the central part of the Oval area by OVD026. It includes a massive sulphide intercept in hole OVD026 of 1.8 metres of 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co from 105.0 metres within broader mineralisation of:
- 19.8 metres of 1.23% Cu, 0.98% Ni, 0.36g/t E3, and 0.05% Co from 91.2 metres.
OVD026 is located 100 metres northwest of the previously announced 8.8 metres of massive sulphide identified in drillhole OVD021.
On completion of the Phase 2 exploration work and receipt of all assays, Managing Director Gan-Ochir Zunduisuren, commented:“The 2024 Phase 1 and 2 drilling and exploration programs have confirmed the broad presence of high-grade mineralisation in the Oval gabbroic intrusion. The grades intercepted in some of the drillholes are exceptional and may be indicative of broader potential over a larger area, given Oval is a greenfields discovery.
The 2025 exploration program will focus on obtaining information on the size/metal content potential of the Oval Cu-Ni-PGE mineral system as well as targeting the possible deeper magmatic sources at Oval. Broader exploration is also planned at potential extensions of Oval and nearby look-a-like prospects. We look forward to updating shareholders on progress, with drilling expected to commence in around 8 weeks”.
Summary of Phase 2 exploration drilling at Oval Cu-Ni-PGE project
The Company’s recent drilling work has predominantly focused on finding high-grade mineralisation in the olivine-amphibole gabbro at the Oval project. The multiple intercepts of massive sulphide mineralisation with different ratios of metal contents throughout the Oval gabbroic intrusion is highly encouraging for the presence of one or more deeper sources of high grade mineralisation in the opinion of ABM.

Drillhole OVD02c
Drillhole OVD026 was designed to test the Down-Hole Electromagnetic (DHEM) conductor plate identified as OVD007_L2_B (reinterpretation of OVD007_L2_A2 by Southern Geoscience Consultants), which exhibits a conductance of 1,000 siemens. The drilling intersected a total of 1G.8 metres of mineralisation with 1.23% Cu, 0.G8% Ni, 0.36g/t E3, and 0.05% Co from G1.2 metres including;
- 4.8 metres of @ 0.45% Cu, 0.43% of Ni, 0.14g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 91.2 metres,
- 6.6 metres of @ 1.56% Cu, 0.G0% Ni, 0.50g/t E3, and 0.04% Co of net textured mineralisation from G6.0 metres,
- 2.4 metres of @ 1.52% Cu, 1.3G% Ni, 0.43g/t E3, and 0.07% Co of semi massive sulphide mineralisation from 102.6 metres,
- 1.8 metres of @ 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co of massive sulphide mineralisation from 105.0 metres, and
- 4.2 metres of @ 0.57% Cu, 0.45% of Ni, 0.21g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 106.9 metres (Table 1 provides a detailed breakdown of mineralisation intervals).
OVD026 is located in the Oval area, which is approximately 100 metres northwest of the previous intersection identified in drillhole OVD0213. This intercept may represent an extension of the known massive sulphide mineralisation in the Oval area and highlights the potential for further expansion of massive sulphide zones within the broader prospect area (Figures 1 and 3).
