Northern Zone Gold Project Drill Results

Oracle Power PLC (AIM:ORCP), an international project developer, notes the announcement released on the ASX by its farm-in partner, Riversgold Limited (ASX: RGL) ("Riversgold") on 18 September 2024 and is pleased to provide an update on the Northern Zone Gold Project in Western Australia ("Northern Zone" or the "Project").  

Highlights

·    The latest aircore drilling at Northern Zone, located 25km east of Kalgoorlie, continues to tag the top of an extensive gold-bearing porphyry system.

·    Drilling has tagged the top of a blind porphyry system, with widths now approaching 600m.

·    Drill results from the first 8 of the 30 completed holes have now been received, further validating the geological model for the previously announced Exploration Target at the Project of 200Mt - 250Mt at a grade of 0.4 g/t Au - 0.6 g/t Au for 2.5Moz - 4.8Moz of gold¹.

·    Further drilling results will be announced in due course.

Naheed Memon, CEO of Oracle, commented:

"Riversgold's exploration and resource definition work at Northern Zone continues to yield promising results. These latest results demonstrate that the porphyry system discovered at Northern Zone may be larger than originally indicated extending up to 600m in width. Northern Zone is in a highly active and exciting phase of work as planning continues to drill across the tenement to further explore the upper elevation of this blind porphyry. We look forward to receiving and providing further assay results in the coming weeks as we begin to get a true picture of the potential size and scale of this exciting discovery."

¹ The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The reader is advised that an Exploration Target is based on existing drill results and geological observations from drilling as well as interpretation of multiple available datasets. The Exploration Target is based on historical third party and Oracles drilling results. It uses data from 53 historical drillholes drilled between 1998 and 2012, and 7 drillholes drilled by Oracle in 2021.

Riversgold's ("RGL") ASX announcement:

GOLD PORPHYRY INTERCEPTS CONTINUE TO BE DRILLED

NEAR KALGOORLIE

Highlights

·    The latest aircore drilling at Northern Zone, located 25km east of Kalgoorlie, continues to tag the top

of an extensive gold-bearing porphyry system.

·    Drilling has tagged the top of a large, blind porphyry system, with widths now approaching 600m (refer to Figure 1).

·    Drill results from the first 8 of 30 completed holes have been received, further validating the geological

model for the previously announced Exploration Target at the Northern Zone Gold Project of 200Mt

·    250Mt at a grade of 0.4 g/t Au - 0.6 g/t Au for an Exploration Target of 2.5Moz - 4.8Moz of gold.^*

·    Further drilling results are pending.

David Lenigas, Chairman of Riversgold, said: "Our latest drilling and geological modelling at Northern Zone has confirmed the presence of significant gold within this expansive, yet still undefined, massive porphyry system located just east of Kalgoorlie, Western Australia. We've now identified that the porphyry system may be much larger than originally prognosed, with one section, as shown in this release, extending up to 600m in width. We are developing plans to drill across the tenement to further explore the upper elevation of this blind porphyry. Additional drill results are pending, and this gold project is fast becoming very interesting."

Riversgold Limited (ASX: RGL, Riversgold or the Company) is pleased to announce that it has received the first

batch of assay results from aircore (AC) drilling undertaken during Riversgold's third 2024 aircore program at

the Northern Zone Intrusive Hosted Gold Project, located 25km east-south-east of the Kalgoorlie Super Pit in

Western Australia (refer to Figure 2 for location).

Following on from our successful aircore programs completed in May and July 2024, Riversgold engaged drilling contractor, Australian Aircore Drilling (Mick Shorter), to undertake a third aircore program for a further 30 holes in late August and early September 2024. 1,826m of AC drilling was completed at Northern Zone in the most recent drilling campaign bringing the total number of metres drilled this year to 5,501m of AC drilling and 1,363m of reverse circulation drilling.

The AC holes were drilled using a blade to drilling refusal. The cuttings were logged by RGL geologists, and both the detailed logging and assays continue to show that a significant gold mineralisation event has taken place within the project area.

All historical and recent drilling data for a total of 167 drillholes at the Northern Zone Project has now been uploaded into Leapfrog software and has enabled the Company to generate a gold grade model (refer Figure 1 above). Leapfrog will now be used to guide the next round of drilling, as we continue to build the project.

Results from the first 8 holes of the most recent 30-hole program have been received with significant intercepts including:

§ 4m @ 0.63 g/t Au from 27m (NZAC081)

The above results indicate that we are successfully continuing to probe the porphyry over an increasing footprint within the tenement. We will continue drilling to further our understanding of the project before proceeding with a Mineral Resource Estimate (MRE).

Mineralisation remains open in multiple directions, necessitating further drilling campaigns. Refer to Figure 3 for drilling locations, and Tables 1 to 3 for location and assay results.

Saturn Metals Limited has released a Preliminary Economic Assessment (PEA) on the Apollo Hill Gold Project which is located 175km due north of Northern Zone. With a resource estimate of 105Mt at 0.54g/t gold, totalling 1.839Moz[5], this development serves as a benchmark for our aspirations at Northern Zone, albeit with the potential for Northern Zone to be an even larger project.

Conceptually, the Company draws parallels between Northern Zone and Saturn Metals' Apollo Hill Project, discerning similarities based on the PEA statement released by Saturn Metals (ASX announcement of 7 August 2023), which suggests the potential for a sizeable low-grade heap leach operation.
