Monument’s Drill Assay Results Highlight Selinsing Gold Mine Expansion Potential
Vancouver, B.C., May 29 , 2026 - Monument Mining Limited (TSX -V: MMY and FSE: D7Q1)
("Monument" or the "Company") is pleased to announce the results of a n additional twenty-three
(23) holes that have been received with high gold assay results from the Buffalo Reef/Felda areas and
updated drilling activities , under the mine expansion drilling program at the Selinsing Gold Mine ,
located in Pahang State in the Central Gold Belt of Western Malaysia.
Ms. Cathy Zhai, President and CEO of Monument commented: "The drill assay results reported in this
announcement underlie the strong potential for resource addition outside of the Life of Mine (“LOM”)
and the Expanded Pit Shell. We have deployed more drill rigs and continue to improve the efficiency
of exploration.”
The Stage 1 and Stage 2 drilling for mine expansion program have completed, including 123 holes for
17,136m, compared to the planned 118 holes for 17,477m. Further drilling programs are under review.

BUFFALO REEF/FELDA MINE EXPANSION DRILLING
Buffalo Reef/Felda mine expansion drilling (Figure 1) contains Stage 1 and Stage 2 as a part of the
Selinsing gold mine expansion program. The target area covers 115 acres of land, laying the foundation
to evaluate the potential to extend the currently defined Mineral Resources , and to convert the
3 | 26
current resources to reserves that are currently constrained by tenement boundaries. Success of
exploration may potentially support the pit expansion at Buffalo Reef/Felda [1] and inform future LOM
planning, subject to the tenement extension.
Figure 1: Long section through Buffalo Reef Central depicting Mine Expansion target Areas (Stage 1 and Stage 2) targeted
in the Mine Expansion Drilling, looking west.
An additional twenty-three (23) assay results were received from diamond drill holes (Figure 1 and
Figure 2). Drill holes continue to intersect multiple zones of gold mineralization in Stage 1 and Stage 2
targets. Continuity betwe en previously modelled mineralized domains, and mineralized intervals
intersected in drill holes , and between some drill holes is evident , which will likely result in an
increased Inferred Mineral Resource.

STAGE 1. Buffalo Reef “Gap” Drilling
Stage 1 Buffalo Reef/Felda Expansion drilling program focuses on evaluation of the potential resource
increase to bridge the gaps between BRC2/BRC3 and between BRC3/BRC4 (Figure 1), to enable the
pits to be combined and expanded, which may inform future LOM planning subject to further studies.
Eleven (11) of the Twenty (23) holes reported in this announcement (Table 1) targeted BRC2 / BRC3
Gap and the BRC3 / BRC4 Gap.
BRC2/BRC3 “Gap”
Drilling around the BRC2/BRC3 Gap continues to demonstrate continuity between drill holes and the
existing resource domains. The successful intersecting of gold mineralization targeting the projection
