High Grade Gold Mineralisation Beneath Mt Boppy Pit Extends Further
Highlights:
-
RC drill holes collared at surface continue to extend the zone of high-grade gold mineralisation beneath the Mt Boppy design pit shell reported previously in announcements on 24 August 2020, 25 September 2020 and 4 December 2020.
-
Assays from four drill holes have been received and incorporated into 3D modelling.
-
Best intercepts from four holes drilled on sections approximately 25m apart:
oHole MBRC019: 22m @ 11.78 g/t Au from 159m downhole depthoHole MBRC020: 17m @ 4.33 g/t Au from 180m downhole depth -
Intercepts are 30-50m below the current planned pit floor confirming the existence of high grade mineralisation outside the current pit shell
-
Economic analysis of gold potential below current proposed pit floor will commence when further results are received
Manuka Resources Limited (“ Manuka ” or the “ Company ”) is pleased to provide an update on the recent drilling at the Company’s Mt Boppy gold deposit. Four reverse circulation (RC) drill holes were designed to test the down-dip extents of high-grade gold mineralisation defined by previous RC grade control and surface drilling.
MBRC019: 159m – 181m (22m) average 11.78 g/t Au (no stope fill included) Including 159m – 165m (6m) average 5.37 g/t Au And 174m – 181m (7 m) average 30.98 g/t Au
MBRC020: 180m – 197m (17m) average 4.33 g/t Au (no stope fill included)
These intercepts are approximately 30m to 50m beneath the current planned pit floor. Following the exceptional extension drilling announced on 24 August 2020, 25 September 2020 and 4 December 2020. These results again confirm the existence of exciting grades of gold mineralisation below the current pit shell.

Technical detail
The reported drill holes were designed to follow up previously reported high grade intercepts in the hangingwall (west side) of back-filled stopes in the Mount Boppy gold deposit. High grade zones were encountered in historic drilling and mining higher in the deposit, associated with dip and strike flexures of the Mount Boppy Main Lode.
Holes in this drill program were collared at surface at approximately 280m RL on the western side of the current pit. All holes were originally planned as moderately to steeply east plunging to intersect steeply west dipping mineralisation at a high angle, approximately 25m – 30m down-dip from previously drilled high grade zones. The first two holes, MBRC019 and MBRC020, proceeded well and intercepted the Main Lode within 3.5m and 8.5m respectively of their planned locations. MBRC021 and MBRC022 deviated significantly, intercepting the lode 18m and 11.2m from plan respectively. Full details of drill hole sample results for reported holes are given in Table 3.
Figure 1 shows a long section view looking east of the Mount Boppy deposit in the vicinity of reported drill hole intercepts and previously reported holes are also indicated. The grey shaded background is a surface representing the western margin of stoping that occurred when Mount Boppy operated as an underground mine from 1900 to 1923. During underground mining these stopes were backfilled with tailings sands that contain significant gold grades and form part of the Mount Boppy resource. Figure 2 shows the location of reported drill holes on the 280m RL on the western side of the Mt Boppy pit. Figure 3 and Figure 4 show east-west oriented cross sections through the reported drill holes, with the current design pit shell and backfilled stope volumes indicated.
The zone of high grades corresponds with a strike and dip flexure of the Mt Boppy main lode, reflecting the strong structural controls on mineralisation.
Manuka’s Executive Chairman Dennis Karp said: “The ongoing drilling campaign into the existing Mt Boppy pit, targeting mineralisation beneath the current pit design, continues to deliver excellent grades. This is the fourth set of drill holes the Company has reported on since August 2020, and all four sets significantly contribute to the thesis that Mt Boppy has potential to have a much longer life than currently planned. We are certainly incentivised to continue exploration to build our resource inventory for future exploitation. We have planned further drilling to intersect below the current pit design (again from surface) and expect these holes to be completed midMarch.
The current strategy for Manuka is to conclude mining the current Mt Boppy pit design by May/June 2021, and process those mined Mt Boppy ores until around July. We then intend to commence the processing and production of the Wonawinta stockpiles, as we become Australia’s newest silver producer, and notably Australia’s largest primary silver producer.”

Geology Deposit type, geological setting and style of The Mount Boppy deposit is located in the northern part of
mineralisation. Devonian Canbelego-Mineral Hill Rift Zone, flanked by the
Kopyje Shelf, on the far eastern side of the Cobar Basin.
Mineralisation occurs in brecciated and silicified sediments and
quartz veining developed along a west-dipping fault that down-
throws Devonian aged Baledmund Formation rocks on its
western side against Orodovician age Girilambone Group rocks
on it eastern side.
The Main Lode strikes approximately north-south and dips at
approximately 70-80° west.
The best mineralisation in wall rocks occurs within the
Baledmund Formation rocks on the western side of the Main
Lode where the lode has a shallower dip.
Historical underground workings were supported with timber

| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect _(eg ‘down hole length, true width not known’). _ |
True widths are estimated to be 70-75% of the down-hole intercept width. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Diagrams and tabulations of intercepts are included in the body of the report. |
| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
The drill hole intercepts reported represent a high grade portion of the Mount Boppy gold deposit and are not representative of the entire dip and strike extent of mineralisation. Cross sections of entire drill hole results are provided in the body of the report. |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
Boppy mineralisation is processed at MKR’s Wonawinta plant, which uses a carbon-in-leach (CIL) process to extract gold, generally achieving recoveries of between 75% and 80%. |
| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Results from this programme will be assessed more fully to determine if further drilling is required. |
