Northern Zone Update: Completion
of Diamond Drilling
Oracle Power PLC, an international project developer, is pleased
to announce an update in relation to further development of
Northern Zone project by Riversgold Limited ("Riversgold"). On 9
May 2023, Oracle announced signing of a binding Heads of Agreement
with ASX listed Riversgold to farm-in to licence P25/2651, known as
the Northern Zone Gold Project, located 26 km east of Kalgoorlie in
Western Australia (the "Northern Zone" or the "Project").
Riversgold has today announced it has completed its maiden
diamond drilling programme at the Northern Zone.
Drilling Highlights:
-- Diamond drilling of entire central cross-section to 450m
vertical depth completed to validate exploration model
-- Previously announced exploration target of 200Mt - 250Mt at a
grade of 0.4 g/t Au - 0.6 g/t Au for 2.5Moz - 4.8Moz of contained
gold from historical drilling
-- Visible alteration on all holes exceeded initial expectations
with all four holes drilled deeper than planned
-- Programme aim was to:
o Confirm the mineralisation style
o Mineralisation widths and gold grades
o Oriented core to gather structural orientation of the
mineralisation
-- Drill cores are now being moved to ALS in Perth for cutting, photography and assay
CEO of Oracle, Naheed Memon, commented: "I am very pleased to
see this promising update on our Northern Zone asset from
Rivergold. Prior to this, Oracle's work at the Northern Zone, had
established that the gold system encountered at the project has
potential scale, with a multi-million-ounce gold exploration
target. This has been substantiated today with very wide zones of
intense alteration in all four diamond drill holes demonstrating
the high gold prospectivity. We will eagerly await further updates
on gold grades and widths in due course.
"Following Oracle's initial exploratory work leading to the
diamond drilling programme, Riversgold took little time to get on
the ground at Northern Zone. With a local, and ASX listed partner
who has exploration and development expertise in the region, we are
well placed to deliver for the benefit of our shareholders, and we
look forward to sharing further updates of the results of the
drilling as we work towards firming the gold prospect at Northern
Zone."

without material adjustment and can be found at

"Riversgold Limited (ASX: RGL, Riversgold or the Company)
announces that it has completed its maiden diamond drilling program
at the Northern Zone Intrusive Hosted Gold Project located 26 km
east of Kalgoorlie in Western Australia. Refer to Figure 1 for
location.
On the 9 May 2023, RGL announced the acquisition of an 80%
earn-in to Northern Zone. A 4 hole, 1,379m oriented core diamond
drilling program has now been completed and RGL expects to complete
the earn-in commitments for the 80% interest in the tenement, once
the assays and reporting have been completed.
The Northern Zone Project has an Exploration Target of 200 to
250 million tonnes at a grade of 0.4 g/t to 0.6 g/t for an
exploration target of 2.5 to 4.8 million oz of Gold, announced by
RGL to the ASX on the 9 May 2023.
Cautionary Statement: 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 and Oracle drilling
results. It uses data from 53 historical drillholes drilled between
1998 and 2012, and 7 drillholes drilled by Oracle in 2021. Refer to
Appendix 1 for further information with respect to these
exploration results.
The initial aims of the first phase of diamond drilling
exploration at Northern Zone are to confirm the mineralisation
style, confirm the very wide widths of gold mineralisation seen
previously in the RC Drilling, and confirm gold grades and gold
distribution. Secondly, the aims are to generate mineral
orientation and structural information and lastly to generate
sufficient core to allow for both metallurgical studies and allow
for the geophysical characterisation of the core with the view of
potential using this information to fast track and better define
the size of the mineralised envelope, through improved drill
design. RGL is optimistic that all these aims and milestones can be
achieved from the drill core.
David Lenigas, Executive Chairman of RGL, said: "The very wide
zones of intense alteration in all 4 diamond drill holes on this X
section demonstrates the high gold prospectivity of the Northern
Zone Project and endorses RGL's investment in this project in a
well-endowed Province, which is seeing the emergence of intrusive
related gold hosted mineralised systems as a genuine host to gold
mineralisation. The big questions on actual gold grades and widths
will be answered when ALS complete their work in their Perth
facilities over the coming weeks."
The Northern Zone Project is located 26km, east-south-east of
the Kalgoorlie Super Pit and is readily accessed from the Bulong
road, which is paved to within 9km of the prospect site. The last
9kms consists of 4km of a high-quality haul road with the last 5kms
on a station road. The topography is flat lying, open scrub with
several historical remnant gold and nickel excavation pits less
than 5 kms from the prospect site.
Drilling Contractor DDH1 completed the drilling at Northern Zone
using a combination of HQ3 and NQ2 diamond drilling. The core was
logged by contract geologists BMGS in Kalgoorlie, with oversight
from RGL geologists. The detailed logging showed that the host rock
to the mineralisation is structurally competent and tonalitic in
composition. The mineralisation event has introduced significant
micro-fracturing and quartz veining, which acts as the conduit for
the significant thicknesses of silica, albite, hematite and
fine-grained pyrite alteration (Figure 2, Table 1). This style of
alteration is the typical alteration pattern associated with
intrusive gold related mineralisation. Internal to the broad zones
of alteration are narrower zones of more intense alteration and
complete textural destruction of the host rock (Figure 3).
Cautionary Statement: RGL has not yet quantitatively determined
whether the core is gold mineralised or not. The core photograph is
provided to support RGL ' s hypothesis that Northern Zone is likely
to be an Intrusive Relative Gold Deposit (IRGD) model where
mineralisation occurs in microfractures associated with
hydrothermal fluids which is visually evident in the core and is
associated with alteration of the more brittle host rock. The
diamond drill holes are within a central drill section where RC
drill results for gold were previously reported (See ASX release 9
May 2023 " Farm into Significant Porphyry Hosted Gold Project "
Next Steps
RGL will:
-- Complete logging of the core,
-- Undertake core cutting and sampling of the core,
-- Complete interpretation of the geological and assay results
upon receipt of the assay results,
-- Undertake further metallurgical test work if warranted,
-- Undertake further drilling towards defining a resource at Northern Zone.
