Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“This is the result we have been working towards all year. With less than 15,000m of targeted, efficient drilling we have added over 470 koz to the Ricciardo deposit, doubling the Resource.
We are excited by both the outcome itself, and the outlook that it delivers us for the wider corridor of gold deposits. The simple strategy of drilling below shallow open pits to find mineable ounces worked exceptionally well for our producing neighbours. The validity of this strategy is now beyond doubt, for us.
Not only is the Ricciardo system still wide open down-plunge, but the entire 25km long ‘Golden Corridor’ offers similar potential upside from such a relatively simple drilling focus.
In the middle of the infrastructure-rich southern Murchison, and located on existing Mining Leases, the opportunity in front of us is utterly irresistible.”
The Ricciardo Deposit
The Ricciardo Gold Deposit is located on existing mining leases 100% owned by WA8, in the Murchison Region, approximately 300 km east of Geraldton, and 420 km by road north-northeast of Perth. Sitting approximately 8km South of the Golden Range Mill on M59/421, and M59/458, within the Golden Range group of historic open pit mines and deposits.
Discovered in the 1990’s, open pit mining of the oxide resources commenced in 2001, and the plant entered Care & Maintenance twice (between July 2004 and 2009, and May 2010 to mid- 2013). Production was over 300 Koz before finally going into ongoing Care and Maintenance in August 2019.
The Ricciardo deposit is located 90km north of Capricorn Metals’ Mt Gibson Gold Project, 8kms south of the Company’s plant, 26km from the neighbouring Golden Grove processing facility and 40 km northeast of Vault Minerals’ high grade Rothsay gold mine (Figure 1).
Figure 1: The location of the Ricciardo gold deposit within the Golden Range Project; within the broader Southern Murchison region.
The Ricciardo gold system spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth prior to Warriedar drilling. Historical mining operations at Ricciardo were primarily focused on oxide material, with the transition and primary sulphides mineralisation not systematically explored.
Warriedar’s drilling of Ricciardo during CY2024 achieved excellent results, demonstrating high- grade extensions to the resource. The results demonstrated that the previously quantified resource is part of a much larger system.
Warriedar engaged independent mining consultants, Measured Group to update the Ricciardo MRE, previously reported 476Koz gold.1
The Ricciardo Gold Deposit consists of six semi-continuous historical open pit mines along the 2.3 km arcuate stretch of the Mougooderra Shear Zone, running north to south. These mines are named (from north to south) Silverstone North, Ardmore, Copse, Silverstone, Silverstone South, and Eastern Creek (Figure 2).

HIGHLIGHTS:
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“Following the recent high grade antimony intersections at Ricciardo, our initial review of the broader antimony potential has delivered further promise. An exceptionally high-grade antimony interval, as well as a much wider intersection, are now able to be placed in greater context. This context is a broader volume of antimony, not yet well-defined but with existing drilling showing serious scale and grade potential.
“Importantly, the high-grade antimony appears relatively discrete from higher-grade gold mineralisation, an excellent metallurgical outcome. While it remains early days, we are cautiously optimistic and have commenced initial metallurgical testing for potential processing and antimony recovery.
“While we are excited about this emerging opportunity at Ricciardo, I want to emphasise however that pursuit of this opportunity will be in parallel with our growth-focussed gold drilling at Golden Range, which remains our current core focus.”

Key Ricciardo context
The Ricciardo gold system spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth. Ricciardo possesses a current Mineral Resource Estimate (MRE) of 8.7 Mt @ 1.7 g/t Au for 476 koz gold.1
Historical gold mining operations at Ricciardo were primarily focused on the oxide material, with the transition and primary sulphides mineralisation not systematically explored. Antimony was not a focus of previous exploration, with only about 11% of historic drill holes assayed for antimony.
The gold and antimony mineralisation at Ricciardo is predominantly hosted within intensely altered and deformed ultramafic units. The high-grade antimony-dominant mineralisation occurred later than the main gold events and generally sits above the high-grade gold mineralisation.

HIGHLIGHTS:
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“This final set of diamond results from the recent Ricciardo drilling have really put a bow on the whole program for us. The broad-based extensional success delivered by this drilling is both real and exciting. The fact that these results are being delivered at what are still relatively shallow down-dip depths, and in such proximity to excellent surrounding infrastructure, also delivers excellent potential for the economic character of the anticipated resource additions at Ricciardo. It is my firm belief that we are just getting started in terms of the opportunity at Ricciardo, let alone within the larger ‘Golden Corridor’ and along the broader mineralised shear.”
Key Ricciardo context
The Ricciardo gold system is located within Warriedar’s flagship Golden Range Project in the Murchison region of Western Australia (refer Figures 1 and 2).
Ricciardo spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth. It possesses a current MRE of 8.7 Mt @ 1.7 g/t Au for 476 koz gold. 1 Importantly, historical mining operations at Ricciardo were primarily focused on oxide material, with the transition and primary sulphides mineralisation not systematically explored.

Figure 2: The ‘Golden Corridor’ within the Golden Range Project. The image on the right is gravity over shaded residualmagnetic RTP.
The most recent phase of RC and diamond drilling of Ricciardo has concluded. This release reports on the assays from the final 11 holes of the diamond program. These holes were predominantly located in the southern part of the Ricciardo deposit, focusing on down-dip extension where no previous drilling had been undertaken (refer Table 1 and Figure 3 for drill collar and relevant section locations).
All 11 holes returned significant intersections, delivering a further round of meaningful extensional success from the recent program (refer Table 2). All results are set to be incorporated into an update of the Ricciardo MRE, which remains on track for completion during Q4 2024.

HIGHLIGHTS:
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“The results for these holes successfully demonstrate further extensional high-grade gold, and for the first time very high-grade antimony zones below the Ardmore pit area.
Given the relative absence of assaying for antimony in historical drilling at Golden Range, we are cautiously optimistic on the potential that might exist here. Moreover, the apparent zonation in RDRC067 is also highly encouraging for any future antimony development potential.
I want to emphasise however that pursuit of this opportunity will be in parallel with our growth-focussed gold drilling at Golden Range, which remains our current core focus.”

Key Ricciardo context
The Ricciardo gold system spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth. Ricciardo possesses a current MRE of 8.7 Mt @ 1.7 g/t Au for 476 koz gold.1 Historical mining operations at Ricciardo were primarily focused on oxide material, with the transition and primary sulphides mineralisation not systematically explored.
Due to the limited number of multi-element assays from historical drill holes at Ricciardo, other mineral potential (outside of gold) has also not been properly evaluated historically.
Figure 2: The ‘Golden Corridor’ within the Golden Range Project. The image on the right is gravity over shaded residual magnetic RTP.
The gold mineralisation at Ricciardo is predominantly hosted with intensified altered and deformed ultramafic units. It is important to note that the newly identified antimony-dominant mineralisation identified in RDRC067 (discussed below) sits above high-grade gold mineralisation in the same area, and may overprint the earlier gold mineralisation in some areas.
High-grade antimony zone discovery below the Ardmore pit
RDRC067 was designed to drill south to north along strike to better understand the structural controls within the Ricciardo deposit and assess the continuity of the ultramafic unit (Figure 3). All previous drill holes (by Warriedar and previous explorers) have been drilled eastward perpendicular to the known mineralised structure. RDRC067 was considered an important hole by the Warriedar technical team in order to confirm there are no additional structural controls and to provide further confidence in the geological model.
Figure 3: Plan view of Ricciardo deposit with current cross section locations annotated. The holes drilled in Q2/Q3 as part of the current program are highlighted in red. Additional holes are also outlined but not presented in below cross sections.
Unexpectedly, RDRC067 intersected significant high-grade antimony mineralisation from 229.2m to 241.9m downhole, returning 12.7m @ 4.98% Sb and 0.36 g/t Au (10.92 g/t AuEq) (Figure 4). Above this high-grade antimony zone, another significant zone was also identified from 183m to 198.1m downhole, returning 15.1m @ 1.42% Sb and 0.42 g/t Au (3.42 g/t AuEq) (Figure 4).
The antimony zones intersected by RDRC067 are interpreted to correlate with a lower grade antimony zone intersected in RDRC038 and RDRC049 (Figure 4). Encouragingly, drillhole RDRC001 returned a wide zone of antimony mineralisation: 34m @ 1.0% Sb and 0.59 g/t Au (2.72 g/t AuEq). Further work is required to determine the geometry and extent of the antimony mineralisation.
RDRC067 concluded at 296.96m downhole depth, within the gold mineralisation domain, as the target depth of the hole had been reached. As RDRC067 is not drilled perpendicular to the Mougooderra Shear, which is the main control of the mineralisation, it is important to note that the intersected thickness does not reflect the true thickness of the mineralisation.

HIGHLIGHTS:
The results for these two (2) holes again demonstrate wide infill of the broader Ricciardo deposit at depth, further validating the outstanding Mineral Resource Estimate (MRE) growth potential that exists at Ricciardo and along the broader ‘Golden Corridor’ trend (refer Figure 2).
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“The outcomes of these two diamond tails are significant, given that they represented substantial depth step-outs under the shallow Ardmore pit. A 77m wide mineralised zone (downhole) with a central high-grade shoot (4.51 g/t), 180m below the MRE is a great result. We don’t fully understand the structural geometry here yet, but we are delighted that the deeper part of hole 49 validates the drill results from a previous explorer – confirming the deposit extends to about 460m vertical depth and retains some good grade (3.19 g/t). Excellent progress.
We continue to drill ahead at Ricciardo as part of the current diamond program, with follow-up growth drilling activities in planning for the remainder of H2 2024.”

North Bay Resources, Inc. (the " Company " or " North Bay ") (OTC: NBRI) is pleased to announce delivery of 344 lbs. of gold concentrate to the Company's refinery partner Just Refiners, Reno, NV. Assay splits have been sent to ALS Geochemistry Reno, Nevada. Ore from the Company's Fran Gold Project was processed at the Company's Bishop Gold Mill. The concentrate represents approximately 15 tons of gross ore processed. Recent repairs to the Company's RakerClassifier and replacement of balls in the ball mill have been implemented to produce a finer grind targeting minus 150 mesh. This grind has been determined to be optimal for recovery. The concentrate is from the gravity only circuit with the flotation circuit currently under optimization and testing ( See Pic 1) . The Company recently received settlement on its first concentrate shipment ( see Press Release dated April 7, 2025 ),
Pic 1. Bishop Gold Mill Flotation Cells.
Flotation Circuit
The Company is testing and optimizing the flotation circuit at the Bishop Gold Mill. The testing of the Clarkson-Feeders for titration of the 5 reagents utilized in the flotation process has been completed.
The staged implementation of the final order of reagents, conditioning and residence time is being determined based on prior metallurgy work and existing equipment. The flotation chemistry utilizes a conditioner, gold promoter, sulphide promoter, activator, and frother. Determination is now underway to identify whether performance will be improved through staged addition of conditioner, gold and sulphides promoters followed by activator and frother or whether reagents will be combined in the single existing conditioning tank. Prior design utilized the ball mill and classifier as entry points for the initial 3 reagents, followed by activator and frother in the conditioning tank. The Company has added a centrifuge, for gravity primary design. This eliminates the possibility of treating the ore in the crushing circuit and reagents now must be added post-gravity recovery in the conditioning tank. A determination is being made to mix all reagents in a single step or adding a second conditioning tank for two phase reagent mixing either collectors and then activator/frother or two dosage mixing of all reagents. A final determination is expected shortly regarding the use of single or double conditioning tanks, with full-scale implementation of the flotation circuit to follow. All mechanical components are working and post-processing equipment including leaf-press and propane fired concentrate drying circuit are operational as well. Previous metallurgy work has determined a 97% recovery may be achieved with a combined gravity and flotation circuit with Fran Gold ore (see Press Release dated December 16, 2024 ).
Fran Gold Project
Data re-compilation of the 104 drill holes from Fran Gold continues. This now includes implementation of Leapfrog 3D modelling and resource estimate software, inclusive of pit-shell design for purpose of producing a resource estimate. The recent discovery of a bulk tonnage gold deposit at Fran ( see Press Release dated April 7, 2025 ) including 149m (488 ft.) of 0.9 grams per tonne has resulted in high priority focus on the re-evaluation of the Fran deposit.
Past exploration and development at Fran Gold, including over 18,000m (55,000ft.) of diamond drilling, has shown large intercepts of mixed vein and disseminated gold. The deposit area has been identified to be in excess of 1000m x 100m x 300m within a known strike length of 1700m. The Fran Gold Project is next to Centerra Gold's Mt. Milligan Project, with Reserves of 264Mt grading 0.3 gram per tonne gold and 0.2% copper and proximate to Artemis Gold's Blackwater Mine, with Proven and Probable Reserves of 334Mt grading 0.8 grams per tonne gold. Both Mt. Milligan and the Blackwater Mine are two of the largest new copper/gold and gold mines respectively, in North America.
