Beehive Maiden JORC Mineral Resource Delivers Major Upgrade at Orom-Cross

New Beehive MRE lifts total Orom-Cross resources to 64.3Mt as DFS optimisation
work advances

 

Blencowe Resources Plc (LSE: BRES) is pleased to announce a maiden JORC (2012)
Mineral Resource Estimate for the Beehive deposit, part of the Company's 100%
owned Orom-Cross graphite project in Uganda.

Beehive is one of two substantial new discoveries (together with Iyan) made
through the Company's most recent drilling programme and represents another
major step change in Orom-Cross scale. Following the maiden Iyan JORC Mineral
Resource (which lifted the Orom-Cross resource base by 66% to 43.0 Mt), the
maiden Beehive JORC Mineral Resource adds 21.3 Mt @ 6.58% TGC (Inferred) and
increases total Orom-Cross JORC Mineral Resources to 64.3 Mt @ 6.03% TGC
(Measured + Indicated + Inferred) across Northern Syncline, Camp Lode, Iyan
and Beehive.

This further demonstrates Orom-Cross as a multi-deposit, long-life,
large-scale graphite development with total Orom-Cross JORC Mineral Resources
up 168% since commencement of the Stage 7 programme.

Importantly, the current Beehive JORC Resource has been modelled over only
circa 22% of the Beehive anomaly and largely within the upper 25-30 metres
tested by shallow drilling. Combined with previously reported deep drilling
demonstrating mineralisation continuing to approximately 100 metres depth, the
Company believes Beehive retains significant upside potential beyond the
current modelled area.

With a materially expanded resource base now defined, the Company has been
progressing further DFS optimisation work to incorporate the enlarged
inventory, evolving downstream pathways, and ongoing commercial discussions.
This work is well advanced and a further update is expected prior to the end
of Q2 2026.

 

Highlights:

Beehive Maiden JORC Mineral Resource update;

·      Beehive JORC Mineral Resource: 21.3 Mt @ 6.58% TGC
(Inferred) at a 3.5% TGC cut-off

·      Higher-grade component defined: 17.5Mt @ 7.0% TGC

·      Total Orom-Cross JORC Mineral Resources (revised): 64.3Mt @
6.03% TGC (Measured + Indicated + Inferred) at a 3.5%TGC cut-off

o  Measured Resource: 1.20 Mt @ 5.13% TGC

o  Indicated Resource: 16.41 Mt @ 5.7% TGC

o  Inferred Resource: 46.70 Mt @ 6.17% TGC

·      Stage 7 drill programme impact: total Orom-Cross JORC Mineral
Resources have increased by 168% since commencement of the Stage 7 programme

·      Depth continuity: deep drilling previously demonstrated
mineralisation continuing to >100m at both Iyan and Beehive deposits

·      Beehive scale: the current model covers just 22% of the total
Beehive target anomaly and is largely confined to the upper 25-30 metres of
the deposit

·      Cost Efficiency: these exceptional results have been achieved at
a cost of under US$10/tonne, which is very low by industry standards

·      DFS optimisation update: expected prior to the end of Q2 2026

·    Strategic and funding workstreams: discussions with counterparties
remain ongoing, supported by the increased scale and deposit pipeline as
development planning progresses

TGC cut-off).

Northern Syncline + Camp Lode + Iyan + Beehive = 64.3 Mt.

 Deposit            Measured (Mt)  Indicated (Mt)  Inferred (Mt)  Total (Mt)  Grade
 Northern Syncline  1.20           14.19           8.14           23.53       5.4%
 Camp Lode          -              2.22            0.36           2.58        6.9%
 Iyan               -              -               16.90          16.90       6.0%
 Beehive            -              -               21.30          21.30       6.6%
 Total Orom-Cross   1.20           16.41           46.70          64.30*      6.0%

*Totals subject to rounding. Category splits and grade weighting are as
reported by the Competent Person.

Ore Reserves remain unchanged and are presented separately below.

Table 2: Orom-Cross Ore Reserve Summary (unchanged, JORC 2012)
Northern Syncline + Camp Lode only.

 Deposit            Ore Reserve (Mt)  Grade (%TGC)
 Northern Syncline  20.59             4.99
 Camp Lode          2.49              6.74
 Total Ore Reserve  23.08             5.18

Ore Reserves are a subset of Mineral Resources and are not additive to the
JORC Mineral Resource total. Both Iyan and Beehive deposits are currently
reported as a maiden JORC Mineral Resource only and have not yet been
converted to Ore Reserves.  Further infill drilling is required to bring a
portion of both Iyan and Beehive Resources into Reserves.

 

JORC Mineral Resource Upgrade Confirms Scale and Upside

The maiden Beehive JORC Mineral Resource confirms a thick graphite system at
shallow depths within the modelled area, while previously reported deep
drilling demonstrates mineralisation continuing to approximately 100 metres
depth. Beehive has been modelled largely within the upper 25-30 metres and
over only part of the target anomaly, and the Company believes there is clear
scope for resource growth through step-outs and further modelling.

Key implications of the upgrade:

·      Step-change in scale: Beehive lifts total Orom-Cross JORC Mineral
Resources to 64.3 Mt; reinforcing a multi-deposit, long-life, large-scale
graphite development

·      Resource growth runway: mineralisation remains open beyond the
current modelled area, with step-out and depth upside indicated by drilling to
date

·      Development and mineability: continuity and near-surface
thickness support open-pit development assumptions and low strip potential,
consistent with a low-cost mining profile

·      Metallurgical alignment: grade profile and mineralisation style
remain consistent with prior testwork and current processing assumptions

·      Efficient conversion: conversion expenditure remains
comparatively low, supporting continued definition of additional tonnes and
the potential to upgrade classifications as modelling progresses

With a materially expanded inventory now defined, the Company has been
progressing further DFS optimisation work to incorporate the enlarged resource
base, evolving downstream pathways, and ongoing commercial discussions.

Strategic offtake and funding discussions also continue alongside development
planning, and the Company will provide updates as and when disclosure is
permitted and appropriate, in line with its regulatory obligations.

Blencowe Resources Executive Chairman, Cameron Pearce commented:

"Today's maiden Beehive JORC Mineral Resource is another major step forward
for Orom-Cross. Beehive adds 21.3 million near-surface tonnes at 6.6% TGC,
lifting total Orom-Cross JORC Mineral Resources to 64.3 million
tonnes across Northern Syncline, Camp Lode, Iyan and Beehive.

Importantly, Beehive has been modelled over only 22% of the target anomaly and
largely within the upper 25-30 metres, while deep drilling has demonstrated
mineralisation continuing to below 100 metres depth. We believe this provides
a clear growth runway beyond the current modelled area.

With a materially expanded inventory now defined, we have been progressing
further DFS optimisation work and expect to update the market prior to the end
of Q2 2026.  Strategic, offtake and funding discussions remain ongoing and we
will update the market as appropriate."
