Vancouver, B.C., November 26, 2021, Monument Mining Limited (TSX-V: MMY and FSE: D7Q1) (“Monument” or the “Company”) is pleased to announce drill results from the reverse circulation (“RC”) drilling program at South and Central areas of the Peranggih Gold Prospect (“Peranggih”), located approximately 10km north of Selinsing Gold Mine.
The RC drilling program was carried out from March to July 2021. The main objective of this program is to delineate shallow mineralization approximately 50m below the surface that can be potentially developed and quickly mined to feed the existing oxide plant at the Selinsing Gold Mine should the assay and block model results be satisfactory (Figure 1).

2021 RC Drilling Program
The RC drilling program consisted of 68 RC holes for 3,317m, to a maximum depth of 70m for 3 holes (Figure 2). 3,901 samples were assayed at the onsite laboratory at Selinsing Gold Mine (the “Lab”). The final assay results were received on August 15th 2021. The drill program confirmed the extension of significant mineralization down-dip of the previously explored area by shallow percussion rotary air blast (“RAB”) drilling along the North-West striking shear structure.
Overall, 70% of the designed holes hit gold mineralization above an oxide cut-off (>0.35 g/t Au Au) at relatively shallow depth, 50m below the surface. The results defined wider lower grade mineralization over an 830m long by 60m wide zone (Figure 2).
The 2021 RC drilling was conducted in two phases to optimize each phase, improving the potential to hit the targeted mineralization.
Phase 1 drilling was carried out from March to April 2021 at 20m by 20m nominal spacing and the average depth of 48m, involving 34 drill holes for a total 1,697m. Phase 1 drilling targeted high and low grade shallow mineralization extension at South and Central Peranggih, intercepted during the RC and diamond drilling campaign from February to May 2018 (21 DD holes for 1,015m and 34 RC holes for 1,710m). This target coincides with the eluvial and colluvial material located on the surface down to approximately 15m. Most of the holes were drilled at 600 dip oriented toward west.
Phase 2 drilling was initiated in May 2021 and completed in July 2021 after receiving encouraging assay results from Phase 1, targeting the strike extension of the mineralization at Peranggih South and Central intercepted in the phase 1 drilling. The program involved 34 RC holes for a total 1,620m and the average depth of 48m. The drilling azimuth, hole orientation, average depth, and spacing were similar to the Phase 1 program. Two reconnaissance holes were drilled at the southern part of Peranggih North to test an anomalous area.
The Company implements a thorough internal Quality Assurance/Quality Control (“QA/QC”) protocol on all aspects of sampling and analytical procedure. Rock chips are monitored, collected, marked for sampling, and logged. Certified Reference Material ‘CRM”, duplicates, and blank samples are inserted based on industry standard practice. The samples were assayed internally at Selinsing laboratory using fire assays with Atomic Absorption Spectrometer (“AAS”) finish.
All blanks reported Au value below the recommended value, indicating low-risk contamination at the laboratory. All CRM’s assay values fall within the three standard deviation range. These indicate that all CRMs are performing well, and the result from the lab is considered reliable. Duplicate samples show good repeatability, potentially indicating that low cross-contamination takes place in the Lab.
Peranggih Geology and Mineralization
The Peranggih mineralization is structurally controlled by the 40-50m wide North-West shear zone. The completed drilling program outlined the extent of the footwall and hanging wall of the mineralized structure. The presence of quartz breccia, tuff breccia, and sheared country rock of argillaceous sediment, tuff and black shale indicates the nature of deformational event responsible for gold deposition at Peranggih. The steeply dipping high-grade (above 1.5 g/t) mineralized structure cuts across the low-grade mineralization at a higher angle and locally occurs at Peranggih South and Central. The spatial location of the high-grade mineralization is shown in the North-South (“N-S”) long section (Figure 3). The low and high grade structures are still open along the strike and down dip. An additional RC drilling program is planned to vector the 560m extension of the mineralized zone along strike and down plunge and dip of the known orebody.
The Peranggih mineralization is commonly associated with matrix-supported quartz breccia. The bulk of the mineralization occurs in a highly oxidized setting, as Peranggih is hosted in a deep weathering environment. The lithologies generally experience moderate argillic and silicification alteration. The structural framework suggests that the mineralized auriferous breccia is emplaced within the shear system with a steep to moderate dip towards the east.
Previous Rotary Air Blast ‘RAB’ Drilling and Follow Up Mining Work
Since January 2020, Monument has actively undertaken 86,870m of RAB drilling at Peranggih and intermittently mined and produced a total of 3,610oz Au as of October 31st, 2021. The shallow RAB drilling at a nominal spacing of 3m x 3m or 5m x 5m with a maximum 20m depth targeted shallow gold occurrences associated with eluvial and colluvium material that exists above the mineralized structure.
As a result of the 2021 RC drilling, an internal block model was produced, and an internal shallow pit shell down to 40m below the surface level was optimized. A total of 55kt of mineralized material was mined and fed to the mill in Q1 2022. Oxide mining and production from Peranggih are expected to increase in the upcoming months.
Peranggih is a fully permitted site having a ten year’s mining lease expiring March 14, 2029.
