Monument Announces Positive Drilling Results At Murchison Gold Projects in West Australia
VANCOUVER, British Columbia, July 07, 2020 (GLOBE NEWSWIRE) — Monument Mining Limited (TSX-V: MMY and FSE: D7Q1) (“Monument” or the “Company”) is pleased to announce exploration drilling results from the company’s Murchison Gold Project at Burnakura and Gabanintha in Western Australia. The drilling program commenced in late February 2020 and was successfully completed in early May 2020 (the “2020 drilling program”). The results have confirmed the continuity of gold mineralization within identified structures and favorable lithology from existing mineral resources.
Highlights:Down plunge extensions of existing high grade gold mineralization was successfully identified at deposits within the Burnakura and Gabanintha Projects.Down plunge exploration drilling at the Yagahong deposit returned:4m at 5.01g/t Au in drill hole 20MRC008 from 139m, and2m at 8.8g/t Au in 20MRC009 from 194m down-hole depths.Down plunge exploration drilling at the NOA 1 deposit has returned:5.77m at 2.13g/t in drill hole 20MRD013 from 237.8m down-hole depth.Confirmation of mineralized structures and favorable lithologies, including the Alliance Banded Iron Formation (BIF).The 2020 Drilling ProgramThe main focus of the 2020 drill program was to test down plunge extensions of existing high grade gold mineralization at both the Burnakura Project (Alliance, New Alliance and NOA deposits), and the Gabanintha Project (Yagahong deposit). The North of NOA7/8 (“NOA 9”) regional target within the Burnakura Project was also tested.The 2020 drill program was planned to consist of 4,580 drill meters for 38 drill holes with a completion targeting late March. Due to additional heritage survey work the drilling was completed in early May.A total of 3,864m was drilled, consisting of 397m of diamond drilling (“DD”), 2,864m of reverse circulation (“RC”) and 603m of AC drilling illustrated in Table 1 below:Burnakura Down Plunge ExtensionThe program successfully tested down plunge targets at Alliance, New Alliance, NOA 1 and NOA 2 deposits at the Burnakura project (Figure 1). A total of 12 holes for 3,080m were planned to test down plunge extensions of high grade gold mineralisation at Alliance (1,005m), New Alliance (850m) and NOA (1,225m). The drill holes targeted high grade gold mineralization with the potential to be mined underground as part of Monument’s strategy to delineate additional resources to improve the economics of the project.A total of 8 holes for 1,577m of RC and 397m of DD were drilled to test down plunge extensions of high grade gold mineralization at Alliance (806m), New Alliance (557m), NOA 1 (264m) and NOA 2 (346m) (See Figure 1). The Burnakura RC and DD holes were all drilled within 2km of Monument’s 260,000 tonnes per annum gold processing plant.The drilling confirmed the continuity of structures and favorable lithology from existing resources, including the best intersection of a 5.77m wide quartz vein at 2.13g/t Au, in hole 20MRD013, from 243m down-hole depth, at NOA 1, which was only tested with one drill hole during this drill program.The drilling was completed in two phases, as a diamond drill rig was mobilized to complete the deeper holes because the RC rig was not able to keep the deeper samples dry. This resulted in some updates to the original drill plan to keep costs within budget. A full listing of drill hole details showing intersections above 1 g/t gold are shown in Appendix 1.Figure 1 accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/b82360a3-1372-4cdb-a596-f49e15d77aa4All Burnakura significant intercepts from this drill program are shown in Table 2 below.*True width intersections are estimated to be approximately 95%, 95% and 80% of drilled widths for Alliance, New Alliance and NOA 1 respectively.
**NSR = no significant resultThe 3 holes drilled at Alliance intersected the same structure and lithology that occurs 170-200m “up dip” in the higher grade areas of the existing resource, confirming the continuity of the gold mineralization and its potential as an underground target. As this drill program consisted of only 3 holes covering a strike length of over 280m, further infill drilling is required to test this target.Drilling at New Alliance targeted approximately 100m down an interpreted plunge of a high grade gold area that has the potential to be mined underground. Although mineralization was weaker than expected, the target is not fully tested and requires additional drilling.A single hole was drilled to target NOA 1 gold mineralization which is interpreted to be located on the same structure that hosts the NOA 2 gold mineralization but is offset by a major east-west fault. The hole intersected a wide prospective quartz vein zone from 237.8m to 243.57m and returned a significant intersection of 5.77m at 2.13 g/t. Due to the potential nuggety distribution of gold within this quartz vein structure, further drilling will be required to fully test this structure and extend the mineralization down dip and further to the south.A single hole was drilled targeting the potential down plunge of the NOA 2 mineralization. The same high potential dolerite-sediment contacts that hosts the mineralization previously mined underground (“up dip”) was intersected. The extension of prospective lithologies was confirmed, and further exploration targeting work will be completed prior to any further drilling.Gabanintha Down Plunge ExtensionA total of 5 RC holes for 1,127m were drilled to test the down plunge extension of the high grade Yagahong gold mineralization (See Figure 2). The drilling successfully extended the known mineralised structure a further 300m down plunge from the existing high grade drilled area. In addition, the deepest down plunge hole that was drilled recorded an intercept of 2m at 8.8g/t gold.Figure 2 accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/c177a2e4-9676-4a72-8a2b-b75fcf5b91ceThe 5 holes at Yagahong were all drilled at least 110m down plunge from existing drilling. Drilling confirmed the continuity of the shallowly north-west plunging structure. Several encouraging gold intersections including 4m at 5.01g/t Au in drill hole 20MRC008, from 139m down-hole depth, and 2m at 8.8g/t Au in drill hole 20MRC009 from 194m down-hole depth were returned (See Table 3). In addition, there were several strong copper intercepts. Hole 20MRC007 returned 14m at 0.97% Cu from 143m down-hole depth, including 3m at 2.86% Cu and hole 20MRC009 returned 3m at 0.85% Cu from 169m.Table 3: Summary of Gabanintha Project Results*True width intersections are estimated to be approximately 95%, 95% and 80% of drilled widths for Alliance, New Alliance and NOA 1 respectively.
**NSR = no significant resultBurnakura NOA 9 Regional TargetThe NOA 9 regional target was tested with 23 AC holes for 603m of drilling. Three east-west lines spaced at 250m and 350m with 40m spaced holes dipping to the west were drilled. The NOA 9 target was identified by Dr. Warwick Crowe (See November 8, 2018 news release) as a potential north-west trending splay off the Burnakura shear zone with a similar structural association of the NOA trend of deposits. The target was tested, but there were no significant intercepts recorded yet. These results will be considered in terms of the overall Murchison package and reviewed in conjunction with geochemical and geophysical data.Forward PlanFollow up drill programs will be planned to target and extend some of the encouraging mineralization and structures intercepted in this drill program. A review of other high potential drill ready targets will also be made so that targets can be reprioritized according to knowledge obtained from this drill program. In addition, an increased focus will now be made on regional exploration potential assessment to capitalize on Monument’s large land holding over its three Murchison projects (Burnakura, Gabanintha and Tuckanarra).Quality Assurance/Quality ControlAll drilling completed by Monument utilized the following procedures and methodologies, and was carried out under the supervision of Monument personnel. Drill contractors used for this drill program included Kennedy Drilling and Mount Magnet Drilling.RC drilling used a 5.50 to 5.75 inch face sampling pneumatic hammer with samples collected into 60 liter plastic bags. Samples were kept dry by maintaining enough air pressure to exclude groundwater inflow; however, a small number of RC samples from this drill program were wet. If water ingress exceeded the air pressure consistently, RC drilling was cancelled and drilling converted to diamond core tails. AC drill cuttings were collected in one meter intervals and split between a calico bag and a portion for spear sampling 4m composites. The 1m calico sample was stored at the drill site until assay results were received and validated. Composites returning greater than 0.2g/t Au were subsampled using the 1m calico bags. Coarse reject samples for all mineralized samples corresponding to significant Au intervals were retained and stored on-site at the Company controlled core yard.DD drill holes were drilled with NQ sized diamond drill bits. The core was logged, marked up for sampling according to geological contacts at intervals between 0.3m and 1.3m length, but was generally sampled at 1m length intervals. 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 Company core yard at the Burnakura camp. The other half was sampled, catalogued and placed into sealed bags and securely stored at the site until shipment.All drill samples were shipped to ALS Geochemistry laboratory in Wangara, WA for preparation. Samples were dried and crushed to 85% passing 75 microns. A 200-250g subsample was then sent to ALS Geochemistry Malaga lab where routine gold analysis using a 50-gram charge and fire assay with an atomic absorption finish was completed. Selected samples were dissolved by a four acid digestion and then analyzed for a suite of 33 elements using an ICP-AES 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 Monument control samples for this drilling program were evaluated and were considered to be of a high standard and no samples were re-analyzed and/or resubmitted. A batch of samples will be sent to another laboratory for cross checking in the near future as part of the QAQC procedure.Qualified PersonsThe scientific and technical information in this press release has been prepared by Adrian Woolford, B.Sc.
