GOLDSTONE RESOURCES LIMITED

("GoldStone" or the "Company")

 

Operational Update

 

GoldStone Resources Limited (AIM: GRL), the West African gold producer and
developer, is pleased to provide an operational update for the year ended 31
December 2025 (the "Period").

 

Operations Overview

 

Operations have continued at the Company's Homase mine in Ghana. Gold
production for the Period totalled 90.6 kilos of gold, equivalent to 2,912
troy ounces, all of which was sold during the Period (refined from 113 kilos
of doré, equivalent to 3,640 ounces). This generated approximately US$10
million in revenue, at an average realised gold price of approximately
US$3,464/oz - compared with a weighted average gold price of approximately
US$3,325/oz during the Period.

 

Total material mined during the Period was approximately 744,000 tonnes,
including approximately 144,000 tonnes of ore, which is consistent with the
reported gold production.

 

Operations during the Period were impacted by a combination of increased
frequency of regulatory inspections, all of which were dealt with in a
professional and satisfactory manner, but nonetheless were time consuming and
diverted management focus from routine operational activities, and an
unusually heavy rainy season which resulted in three months of heavy rainfall.

 

The heavy rainfall disrupted mining operations and the stacking of
agglomerated ore, and average stacked ore volumes reduced from
approximately 36,000 tonnes per month to 14,000 tonnes per month. Leach
performance was also affected during the Period due to increased solution
dilution.

 

Mining and Processing Plan

 

During the Period, the Company continued to advance its heap leach and
processing infrastructure. A new screening and conveying system was completed
and commissioned in December 2025, enabling stacking rates of up to 56,000
tonnes of agglomerated ore per month, providing increased operational
flexibility.

 

Mining in 2026 will continue to focus on near-surface oxide material from the
Homase Mine open pit operations. Ore will be sourced primarily from Pit 3,
which the Company began mining in December 2025, following the completion of
the Pit 1 pushback which gave access to approximately 100,000 tonnes of ore,
which was completed during the Period.

 

The mining schedule has been restructured to maximise production during drier
operational periods, with moderated mining and stacking rates during the
wetter months to reduce the impact of rainfall on mining continuity,
agglomeration and leach performance.  An additional intermediary pond has
been included in the FY26 budget to further mitigate solution dilution.

 

Subject to permitting, and the further expansion of the heap leach pad area,
the Company expects to mine approximately 250,000 tonnes of ore during FY26,
at an average mined grade of approximately 1.0 g/t of gold.

 

Heap Leach Pad Capacity

 

Heap leach operations are dependent on favourable dry-season operating
conditions, and are planned at an average stacking rate of
approximately 36,000 tonnes per month, with the variations between 14,000 -
56,000 tonnes per month, consistent with historical performance,

 

During 2026, ore stacking will be supported by the existing leach pads
together with Pad 6, which is currently under construction and scheduled for
geomembrane lining and commissioning in Q1 2026. Pad 6 measures
approximately 160 metres by 120 metres and represents the largest leach pad
constructed at the Homase mine to date, providing additional stacking
flexibility and operational resilience.

 

Production Guidance

 

Based on the planned mining and stacking profile, heap leach recovery
characteristics of oxide material and the available leach pad capacity, the
Company is targeting total gold production of approximately 4,000 ounces of
gold in FY26.

 

This guidance assumes average metallurgical recoveries of approximately 68%,
in line with historical oxide performance and normal seasonal variability.

 

Financial Performance and Guidance

 

GoldStone has been self-funding since January 2023 and, during the Period,
reduced its historical balance sheet liabilities by settling
approximately US$2.5 million of historical creditor balances.

 

The Company achieved an average All-In Sustaining Cost ("AISC") of US$2,781
per ounce for the year to November 2025.

 

For FY26, AISC is expected to be approximately US$2,500 - US$2,900 per ounce
reflecting:

 

·      Increased stacking and leach pad capacity

·      Improved equipment utilisation

·      Ongoing cost discipline

·      Seasonal rainfall adjustments

 

Capital Expenditure

 

Capital expenditure in respect of the Homase Mine during FY26 is expected to
be limited and largely restricted to:

 

·      Completion and commissioning of Pad 6

·      Expansion of the adsorption plant

·      Construction of an intermediary pond to enhance recovery

·      Routine maintenance capital for mining and processing equipment

 

Community Engagement

 

The Mine Clinic, completed during the Period, is now fully operational and
open to local communities. In addition, construction has commenced on a
new community centre in Krodua village, reinforcing the Company's ongoing
commitment to local development and stakeholder engagement.

 

Board Changes

 

As announced on 22 December 2025, the Company appointed two new directors to
the Board. These appointments are intended to strengthen the Board's
collective experience and support GoldStone as it advances its operational and
corporate objectives.

 

Outlook

 

Despite operational challenges experienced during the Period, the Board
believes that the Homase Mine is well positioned to deliver improved
operational consistency in 2026. With mining access established, enhanced heap
leach infrastructure in place and disciplined planning around seasonal
conditions, the Company remains focused on maximising cash generation,
strengthening its financial position.  This was supported by Asian Investment
Management Services Ltd extending the Gold Loan maturity date to 31 December
2026 and the interest payments being frozen to 30 June 2026, as announced on
30 December 2025, which will help the Company in continuing to develop its
resource base to deliver long-term value for shareholders.

 

Emma Priestley, Chief Executive Officer of GoldStone Resources Limited,
commented:

 

"The past year has seen steady operational progress at our Ghanaian operation.
While we faced challenges from numerous regulatory inspections and unusually
heavy rainfall, resulting in operational disruptions, the team has continued
to advance key infrastructure and improved the Company's financial position
with the added support from our major shareholder Asian Investment Management
Services Ltd.

 

"With the strengthening of the Board, the Company is well placed to continue
focusing on operational stability and incremental improvements as we move into
the next phase of development."
