North Bay Resources Announces Assay of 6.62 Ounces per Ton Gold, Fran Gold Project, British Columbia

Rhea-AI Summary

North Bay Resources (OTC: NBRI) reported assay results from a maiden ore shipment at the Fran Gold Project, British Columbia on Nov 4, 2025. The weighted average of the four test samples was 3.38 ounces per ton (opt), including a high assay of 6.62 opt (sample 25FRTB-5) re-assayed by ALS Global method Au-GRA21.

A tractor-trailer delivery of 10 super sacks (22,597 lbs net dry) is scheduled to the Company’s 96 tpd Bishop Gold Mill for concentrate production and subsequent delivery to the company’s refinery partner in Reno, Nevada. Multi-element assays for Ag and Cu are pending. Fran contains a non-independent estimated resource of 43,797,234 tonnes at 0.34 g/t ( Main+East: 474,001 tr. ounces).

Positive

• Weighted average assay of 3.38 opt from maiden shipment
• High-grade re-assay of 6.62 opt (sample 25FRTB-5)
• Test shipment of 22,597 lbs delivered to 96 tpd Bishop Gold Mill
• Reported resource: 43,797,234 tonnes at 0.34 g/t (474,001 tr. ounces)

Negative

• Ag and Cu assays pending, leaving multi-element grade unknown
• Fran resource is a non-independent estimate, limiting verification

BISHOP, Calif., Nov. 04, 2025 (GLOBE NEWSWIRE) -- North Bay Resources, Inc. (the “Company” or “North Bay”) (OTC: NBRI) is pleased to announce a weighted average of 3.38 ounces per ton gold from the maiden ore shipment at Fran Gold Project, British Columbia. The result now includes an assay of 6.62 ounces per ton gold. As previously announced (see Press Release October 27, 2025) this sample (25FRTB-5) reached the limit of detection and was re-assayed using ALS Global method Au-GRA21. Four samples of ~5lbs each were taken from alternating supersacks, as part of a test shipment of ore from the near surface massive sulphide zone:

Sample number	Weight lbs.	Weight kg.	Au Ounces per Ton	Au Grams per Tonne
25FRTB-1	4.4	2.0	0.41	14.0
25FRTB-4	7.8	3.5	2.64	90.5
25FRTB-5	7.5	3.4	6.62	227
25FRTB-6	5.0	2.3	2.30	78.7

Initial assays were completed by ALS Global, North Vancouver, BC using fire assay method Au-AA25 – Multi-element analysis, inclusive of Ag and Cu assays, are pending.

Bishop Gold Mill

Delivery of the gold ore shipment by tractor trailer of 10 super sacks (22,597 lbs. net dry weight), to the Company’s 96 ton per day Bishop Gold Mill is expected at noon today. The ore will be processed to produce a concentrate for delivery to the Company’s refinery partner Reno, Nevada.

Fran Gold Project

The Fran Property is underlain by Takla Group sedimentary and volcaniclastic rocks intruded by dykes and small stocks of monzonite, monzodiorite and diorite. Previous work, including 55,000 ft. (18,000m) of diamond drilling, has outlined gold-bearing structures featuring broad zones of gold mineralization. In addition to the high grade massive sulphides zone now under development. Fran Gold contains an (non-independent) estimated resource as follows (see Press Release May 13, 2025:

Bullion Alley - Main Zone
Mass (tonnes)	Average (g/t)	Total (grams)	Total (tr. ounces)
20,035,146	0.50	10,051,730	323,170

Bullion Alley - Main Zone + East Extension
Mass (tonnes)	Average (g/t)	Total (grams)	Total (tr. ounces)
43,797,234	0.34	14,743,070	474,001

The East Zone represents a zone of gold and increasing copper resource expansion potential. The deposit also remains open to the South and at depth.

In addition to a broad low grade resource and high-grade surface zone, drill intercepts below the massive sulphide zone indicate continuous high grade gold at depth. For example, DDH FR-59 intersected 16ft. (4.85 meters) grading 0.35 opt gold (10.96 gpt), 1.28 opt silver (40.15 gpt) and 1.48 % copper within a 180 ft. (54m) section averaging 1.2 gpt gold. This zone of cross faulting, which boasts significant bonanza grade material at surface, appears to be the primary feeder zone and is the focus of near term development as feedstock for off-site milling; with a long term focus of construction of an on-site mill to process a significant portion of the drill defined 44Mt of lower grade material.

Fran Gold is located next to Centerra’s Mt. Milligan Mine and regionally proximate to Artemis Gold’s Blackwater Mine two of the newest and largest gold/copper and gold mines, respectively, in British Columbia with comparable gold grades to Fran of 0.5 and 0.8 gpt.
