Monument Mining Limited (TSX-V: MMY) (FSE: D7Q1) is pleased to announce encouraging drill results from a 681m diamond drill program for 14 holes at the Selinsing Gold Mine Pit 4 west wall, which has the potential to increase the current Selinsing gold resources. Additional opportunities for infill and extension drilling were identified (see Figure 1).

Significant Intercept Results
Assay results above 0.35 g/t Au (Monument’s oxide cut-off) are listed below (Table 1) including significant intercepts from MSMDD211 (2m @ 1.06 g/t from 40m), MSMDD215 (2.6m @ 7.62 g/t from 54.2m) and MSMDD217 (8.5m @1.33g/t from 14.5m), which indicates that the mineralization has extended outside of the resources defined in the NI43-101 report (the “January 2019 Snowden Feasibility Study”). However, it does not extend west beyond the currently known footwall plane. Additional information on drilling results from this drill program is shown in Appendix 1, and collar locations are presented in Figure 2.

Pit 4 Drilling and Interpretation
The Pit 4 West Wall is considered the most suitable and prospective opportunity for additional immediate oxide mill feed. Under this drill program 14 holes were drilled for a total of 681m at Selinsing Pit 4. The results from 11 infill holes at the southwestern corner of Pit 4 show promising intersections and confirm the continuity of the high grade mineralized structure within a 60m corridor along the strike length.
North West Wall: Grade control data on the North West Wall suggests that there is significant mineralization left behind that was delineated by previous drilling programs. This mineralization needs to be quantified and better delineated through a short drilling program (see Figure 3: “North West Wall”).

The current pit outlined in the 2019 Snowden feasibility study is based on the resource model from the previous exploration RC drilling results and does not include the grade control information. The close space GC data shows more intense mineralization as compared to the results obtained from RC holes which indicate that the previous drilling may understate the presence of stronger gold occurrence within this area especially within 60 meter strike corridor between section 2100N-2140N.
Three holes drilled (MSMDD 219, 220, 221) at the northwest corner of pit 4 confirmed that the mineralization does not extend west beyond the currently known footwall plane.
South West Corner: There is also a significant portion of shallow mineralization in the southwest corner of pit 4 which has not been included in the current resource model in the 2019 Snowden Feasibility Study. Based on new geological/structural inputs, infill and step out drill holes were designed to extend and upgrade this mineralization (see Figure 4. “Series Sections towards South”).
There is an opportunity to mine the ore located at the pit wall between section 1810N to 1860N approximately within 50m strike corridor (sections ‘c’ to ‘e’). The mineralization in this area contains high and low grade oxide material according to assay results.

The infill drilling results confirmed good continuity of moderately dipping mineralized structures at the southwest corner of Pit 4. Pit optimizations will now need to be run to include the results of this drill program. The mineralization is hosted in quartz stockwork within faulted and sheared tuffaceous sediment.
QAQC on Sample Collection and Assaying
The holes were drilled with NQ2 sized diamond drill bits for drill holes reported in this press release. Employees of Monument conducted all logging and sampling. The core was logged and marked up for sampling using sample intervals of 0.5m to 1.5m according to geological contacts. Samples were then cut into equal halves using a diamond saw. One half of the core was left in the original core box and stored in a secure location at the Selinsing core yard within the Selinsing mine area. The other half was sampled, catalogued and placed into sealed bags and securely stored at the site until it was shipped to SGS Raub, where sample preparation was completed. The core was dried and crushed by the Lab and a 150 gram pulp was prepared from the coarse crushed material.
The gold analysis is completed at SGS Bau, Kuching, using a 30 gram charge and fire assay with an atomic absorption finish. Quality control procedures included the systematic insertion of blanks, duplicates and sample standards into the sample stream. In addition, the Lab inserted its own quality control samples. The results of the control samples are evaluated on a regular basis with batches re-analyzed and/or resubmitted as needed.
