ASX Announcement
24 August 2023
ASX: MKR
360% increase in Mt Boppy Total Gold Resources
80% increase in ‘Measured & Indicated’
Manuka Resources Limited (“Manuka” or the “Company”) is pleased to release an updated
Mineral Resources Estimate at Mt Boppy. Gold production recently recommenced from the Project,
initially from the screening of rock and tailings dumps1.
Highlights:
-
Mt Boppy Total Gold Resources increased nearly 4 fold, to 160,100ozs grading 2.01g/t
Au, including
Measured Resources of 106,850t at 5.25 g/t Au for 18,028 oz gold;
Indicated Resources of 715,088t at 2.54 g/t Au for 58,477 oz gold; and
Inferred Resource of 1,770,335t at 1.47 g/t Au for 83,608 oz gold.
-
Measured & Indicated (M&I) Resources are up ~79% to ~76.5koz grading 3.53g/t
-
First Resource upgrade in over 12 months and incorporates results of recent bulk
sampling and screening evaluation of rock dumps & tailings
-
Manuka reasonably expects to convert most of the Inferred Resource to an Indicated
Resource category as production continues, as well as add additional ounces to the
Inferred Resource
-
Manuka is yet to test Mt Boppy depth extensions which provides scope for continued
Resource growth
Dennis Karp, Manuka’s Executive Chairman, commented:
“Mt Boppy has the makings of an exceptional gold asset. Having started life as a listed company
with 39koz Au in Resources at Mt Boppy, we have produced >41koz Au (560kt @ 3g/t) and still
have almost double that in current M&I Resources. To date we have added an additional 162koz,
of which, importantly, 76.5koz is a measured and indicated resource and work continues on site
with an aim to increase this substantially. The company has yet to test our most prospective
exploration targets.

With the anticipated cash flow from our gold production we are in a strong position to not only
upgrade our Inferred ounces to higher categories but also continue to grow the overall resource.”
Mt Boppy Resource Statement
Mineral resources at Mt Boppy totalling 2,090,423 tonnes at a grade of 1.46 g/t Au for 98,367 oz
Au have been delineated through a bulk sampling and screening evaluation of rock and tailings
dumps on the property ML’s. These are incremental to the total Mt Boppy Opencut Resource,
previously reported to the ASX on 29 July 2022, of 281,850 tonnes at a grade of 4.95 g/t Au for
44,820 ounces, that remain unchanged. The revised total classified Mineral Resources are shown
in Table 1.
The mineral resource estimate for Mt Boppy is contained within:
• in situ rock dumps and tailings depositories, with in situ gold grades derived from bulk
sampling material derived from mechanically pitting and trenching to 2-3m depth and
screening +200, -200+20, +8-20, and -8mm size fractions, with cone measurements to
ascertain mass % distribution and total volume treated.
• an open cut pit shell that reaches a depth of 215m below surface at the southern end of
the Mt Boppy deposit. Resources were reported July 2022 with respect to the current pit
design. Material within the pit design is reported at a 1.6 g/t Au cut off and material below
the pit design is reported to a 3.0 g/t Au cut off. The open cut is currently flooded and
inaccessible for mining. Dewatering and a sidewall pushback is necessary to access and
mine these resources.
• a grade shell modelled at a 1.6 g/t cut off over the Boppy South mineral zone. This prospect
still requires final drilling and evaluation before assessing establishing a small opencast.

The previous resource statement from July 2022 is shown in Table 2.

A summary of the split of the current resources (vis rock dumps, tailings2 and hard rock opencast)
is shown in Table 3.
Table 3 - Mt Boppy Gold Resource by type at 21 August 2023
An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated or
Measured Mineral Resource and cannot be converted to an Ore Reserve. It is reasonably expected
that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources
with continued exploration.
Based on the study herein reported, delineated mineralization of the Mt Boppy deposits is classified
as Measured, Indicated and Inferred resources according to the definitions of the JORC Code
(2012) as presented in Tables 1 and 3. The mineral resource is depleted for the Boppy opencut to
the November 30th 2021 projected pit pick-up, and treated (screened) material on the Boppy ROM
dump as at 21 August 2023.

Rock Dump and Tailings Evaluation
The Company has started producing gold from screening rock dump and tailings material at the Mt
Boppy ROM. Bulk sample evaluation has continued and has progressed evaluation of the Mt Boppy
Main waste rock dump, the low grade rock dump and tailings at the TSF3 impoundment.
This estimate incorporates rock dump evaluation data compiled since the last mineral resources
update 29 July 2022.
The evaluation methodology has enabled assessment of the economic viability of treating
screened rock dump fines plus tailings (these have already been subject to milling and
cyanidation).
The methodology to date has involved:
-
preliminary hand screening on a 40m grid
-
excavation using a 200mm skeleton bucket of 2-3m deep pits on a 40m grid
-
sub 8mm trommel screening of the sub200mm pile, which evolved to sub12mm trommel
screening
-
Triple deck flat screening of sub 200mm piles producing sub10, +10-22, +22-200mm
cones
-
Cones of material were sampled for assay every two front end loader buckets processed
-
Backup splits of each size sample were also taken, as well as pulps prior to bottle roll
analysis
Table 4 (below) shows the quantum of material evaluated for the various material sources. Over
5,000 tonnes of dump material has been bulk sampled to date.
Table 4 - Mt Boppy Dump Evaluation Material Tested
Figure 1 shows a drone image of the Boppy ROM bulk sampling. The screening operation is
centralised, with -8 and +8-20 stockpiles being generated. The work has shown a clear increase
of grade in the -8mm fraction. A +8-20mm split is also generated as a low grade stockpile. Figure
2 shows the indicated grades for the various screened sizes for the Mt Boppy ROM.

Figure 2: Mt Bppy ROM Au g/t vs Screen fraction
Gold analyses have been undertaken on the various size fractions at the Wonawinta Laboratory,
with third party checks conducted at Gekko Laboratory (Ballarat) and ALS (Orange). Analyses
include systematic bottle roll estimation of gold in solution amenable to cyanidation (AAS), analysis
of tails for gold in acid soluble solids (Aqua Regia), combined to give an analysis of total gold in
solution. Bottle Roll and Fire Assay checks were also conducted at Gekko.

About Manuka
Manuka Resources Limited (ASX: MKR) is an Australian mining and exploration company with key assets
located in the Cobar Basin, central west New South Wales. In addition to its recent acquisition of TransTasman Resources Limited owner of the Taranaki VTM Project, it is the 100% owner of two fully permitted
mining projects, one gold and one silver, both within the Cobar Basin, which include the following:
▪
Gold - Mt Boppy Gold mine, 48-person mine camp and neighbouring tenements, hosting an existing
open pit mineral resource3 and combined ROM, waste and tailings material all of which lend
themselves to upgrading through screening. The Company has commenced a screening and gold
recovery project, processing the product at its Wonawinta plant. It has confidence the gold from these
sources can be extracted profitably and over a period of ~3 years. Manuka also awaits the outcome of
its forthcoming exploration program to determine as to whether the future for mining any Mt Boppy
extensions will be as an underground or open cast mine.
▪
Silver - Wonawinta silver project, with mine, 84 person mine camp, processing plant and neighbouring
tenements. Previously renowned as the largest primary producer of silver in Australia, the mine hosts
a significant JORC resource4. The Wonawinta processing plant has a nameplate capacity of >850,000
tonnes per year (which the Company now sees expanded to >1.0Mt/yr. The Company has recently
completed a plant and metallurgical recovery optimisation.
There exists a number of highly prospective base metals exploration targets on Manuka’s ~1,150km2
tenement package within the Cobar Basin.
