Metallurgical Drilling Outlines Robust Gold Zones
Assay results from continued metallurgical diamond drilling at Apollo Consolidated’s (ASX:AOP) Lake Rebecca project have confirmed excellent grade and width continuity and further strong validation of the April 2021 Mineral Resource estimate block model.
The company has now received the remaining assays from HQ diameter diamond drill holes at Apollo’s 100%- owned Lake Rebecca Gold Project located 150km east of Kalgoorlie in Western Australia.
The latest drillholes targeted mineralised structures typical of the average Mineral Resource estimate grade and have provided bulk composite material for continued metallurgical studies. The drilling was also designed to add geological information between existing drill sections.
The company reported that excellent width and grade continuity in the areas tested and a strong validation of the April 2021 Mineral Resource estimate block model.
Drillhole MET001 at the 195,000oz Duchess deposit was drilled on a 20m spaced infill line and intersected 32m @ 1.56g/t Au from 25m, 30m @ 1.47g/t Au from 61m, 16m @ 0.97g/t Au from 98m and 16m @ 0.90g/t Au from 118m.
A zone of massive sulphide veining in the µfootwall¶ to the main structure returned 9m @ 2.24g/t Au from 136m, including a section of core showing coarse visible gold grains.
This style of gold mineralisation has not been logged before at this prospect and raises the possibility of a new style of gold mineralisation and the use of downhole EM tools to target vein extensions.
Drill hole MET002 targeted a separate Duchess mineralised zone, also on a 20m infill section, returning 66m @ 1.03g/t Au from 114m and 22m @ 1.35g/t Au from 200m and demonstrating an excellent fit to the MRE block model.
Drill hole MET003 at the 65,000oz Duke deposit intersected 97m @ 1.85g/t Au from 40m (including 1m @ 25.4g/t Au from 103m and 1m @ 12.5g/t Au from 111m) confirming strong width and grade continuity between the 40m spaced earlier drill sections.
The 1m @ 25.4g/t Au is the highest individual assay in the Duke Mineral Resource drill-out and is an indication of the potential for higher-grade positions along the mineralised structure.
MET005 and MET006 metallurgical drill holes at the 840,000oz Rebecca deposit were designed for the collection of bulk composite material from the moderate grade Laura and Maddy mineralised structures.
Both holes intersected mineralisation conforming with the Rebecca MRE block model, particularly in upper parts of the holes. MET005 returned multiple zones including 11m @ 1.20g/t Au from 34m, 19m @ 1.16g/t Au from 50m, 22.8m @ 1.43g/t Au from 76m and 12m @ 0.84g/t Au from 237m.
A 12m segment of mineralisation was set aside for rock property test work and will be composite assayed at the conclusion of that work.
MET006 intersected 20.8m @ 2.35g/t Au from 80m (incl. 1m @ 17.3g/t Au from 84m), 8m @ 1.82g/t Au from 116m and 17m @ 1.27g/t Au from 138m.
Apollo’s previous metallurgical test work has returned consistent >90% recoveries in fresh rock composite samples using conventional leach processing.
Bulk composite samples have now been collected from this current phase of metallurgical drilling and the next stages of work are underway. The results of current metallurgical and rock-property work will inform ongoing engineering technical studies.
