Manuka Resources Limited (ASX:MKR) is an ASX-listed mining company with gold and silver-gold projects in the Cobar Basin, one of Australia’s most prolific producers of base and precious metals.
The company focuses on its 100 percent owned fully permitted precious metals projects in the Cobar Basin - the Mt Boppy gold mine and Wonawinta silver project. Manuka Resources's development strategy includes bringing back the Mt Boppy gold mine into production and restarting mining and production at the Wonawinta silver mine.
The Mt Boppy gold mine was historically one of the richest in NSW, Australia and produced ~500,000oz gold at an average grade of 15 grams per ton (g/t) gold. Accordingly, the company is very excited about its exploration potential.
The Mt Boppy gold project comprises three mining leases, four gold leases and one exploration license, spanning an area of more than 210 sq. km. in the prolific Cobar Basin in New South Wales, Australia. The project was acquired by Manuka in 2019, and has a current mineral resource of 4.3 Mt at 1.19 g/t gold. This includes a combination of oxidized and transitional/fresh mineralization in the ground, as well as mineralized rock dumps and tailings.
Company Highlights
- Manuka Resources is an ASX-listed mining company focused on exploring and developing gold and silver assets in the Cobar Basin in New South Wales, Australia.
- The company’s two principal assets – the Mt Boppy Gold Mine and the Wonawinta Silver Mine – are both located in the prolific Cobar Basin. In addition, MKR holds a 100 percent interest in the Taranaki VTM iron sands project, located in New Zealand.
- The primary focus is on bringing the fully permitted Mt Boppy mine back into production by Q4 2024. The company aims to establish an on-site processing plant at Mt Boppy and in turn free up the Wonawinta processing plant for silver production from the Wonawinta silver mine, which was being used to process Mt Boppy ore.
- The results of the recently completed sonic drill program coupled with an updated mineral resources estimate at Mt Boppy (100 percent increase in indicated gold ounces) improve confidence in the recommencement of gold dore production at Mt Boppy.
- A dedicated processing facility at Mt Boppy will improve the project economics and also allow for an additional revenue stream by freeing up the Wonawinta processing plant to process ore from the Wonawinta silver mine (placed on care and maintenance in February 2024, and targeting release of its maiden silver reserve under Manuka ownership before the end of June 2024).
- The cash flows from the Mt Boppy mine will be used to fund the restart of the Wonawinta silver mine, which is also expected to become operational by late Q1 or early Q2 2025.
- Elevated gold and silver prices should substantially benefit Manuka Resources, resulting in improved profitability and cash flows as it brings both its gold and silver projects into production.

Manuka Resources Limited
Overview
Manuka Resources Limited (ASX:MKR) is an ASX-listed mining company focused on gold and silver-gold projects in the Cobar Basin, one of Australia’s most prolific producers of base and precious metals. The company has 100 percent ownership of two fully permitted precious metals projects in the Cobar Basin - the Mt Boppy gold mine and Wonawinta silver project. In addition, MKR owns the Taranaki VTM iron sands project in New Zealand.
The company revealed a phased strategy focused on delivering maximum value to its shareholders. The first phase focuses on bringing back the Mt Boppy gold mine into production. The second phase will involve restarting mining and production at the Wonawinta silver mine, while the third phase will see the development of the Taranaki vanadium titano-magnetite (VTM) project.
The Mt Boppy gold mine was historically one of the richest in NSW, Australia and produced ~500,000oz gold at an average grade of 15 grams per ton (g/t) gold. Accordingly, the company is very excited about its exploration potential.
The current focus is on establishing a processing plant at Mt Boppy and recommence on-site gold production from Q4 2024. The ore from the Mt Boppy mine was previously being processed at the 850,000 to 1 million tpa processing plant at Wonawinta, located nearly 150 kilometres south-west of Mt Boppy. This is about to change as MKR has determined that it could save significantly on transportation costs as well as production efficiencies by building an on-site processing plant at Mt Boppy, which will materially enhance the project economics.
MKR estimates the total cost of building the processing plant to be between AU$10 million and AU$15 million. Compared to this, the annual cost of hauling ore from Mt Boppy to Wonawinta is AU$6 million to AU$7 million (nearly 50 percent of the total capex). MKR anticipates Mt Boppy to deliver total EBITDA of >AU$90 million and cash flow of >AU$80 million over a five-year mine life. It is important to note that the current market capitalization of MKR is just AU$55.1 million, much lower than the anticipated five-year EBITDA and cash flow.
The initial five-year mine plan is largely focused on the screening and processing of gold-bearing waste material above ground on the Mt Boppy mine site. The company has been processing these wastes from June 2023 to December 2023 at its Wonawinta plant and now wants to optimize the process.
The cash flows from the Mt Boppy mine will be used to fund the restart of the Wonawinta silver mine, which is currently under care and maintenance. Wonawinta contains total resources of 38.8 million tons (Mt) at 42 g/t silver for 52.4 million ounces (Moz). Within this, there is a higher-grade component of 4.5 Mt at 97 g/t silver for 14 Moz. Manuka Resources is targeting a mineral resource update for Wonawinta in Q2 2024. The Wonawinta silver project will be the largest primary silver producer in Australia and expected to be back in silver production within 12 months.
The gold and silver market appears to be in an upward trend, with prices for both precious metals hitting their all-time high in 2024, which bodes very positively for MKR.

Key Projects
Mt Boppy Gold Project
The Mt Boppy gold project comprises three mining leases, four gold leases and one exploration license, spanning an area of more than 210 sq. km. in the prolific Cobar Basin in New South Wales, Australia. The project was acquired by Manuka in 2019, and has a current mineral resource of 4.3 Mt at 1.19 g/t gold. This includes a combination of oxidized and transitional/fresh mineralization in the ground, as well as mineralized rock dumps and tailings.
Historically, Manuka Resources has processed its stockpiles and gold mineralized waste products through its Wonawinta processing plant. However, inefficiencies associated with trucking and processing ore at the distant Wonawinta plant has led the company to revise its strategy. It is now looking to construct a processing plant at Mt Boppy so that ore from the mine can be processed on-site. Mt Boppy has excellent infrastructure including a 48-person mine camp and is fully permitted for the proposed processing plant and on-site production.
As a precursor to the commencement of on-site production, Manuka Resources undertook a sonic drilling program at Mt Boppy to improve confidence in the mineral resource base. A 26-borehole, 506-meter sonic drilling evaluation program over the Mt Boppy rock dumps and dry tailings was completed in December 2023. The program led to a 100 percent increase in indicated resources compared to the previous estimate.
The updated mineral resource comprises 4.28 Mt at 1.19 g/t gold for 163 koz of contained gold, of which 82 percent is in the measured and indicated categories. A further high-grade subset of the resource (including open pit, rock dumps and tailings) comprising 1.8 Mt at 1.74 g/t containing 102 koz gold has been identified as a basis for future mine planning.
Following the results of the sonic drill program, MKR determined to establish a 200,000 tpa processing plant at Mt Boppy. The company estimates a five-year mine life and a total gold dore production of >48,000 oz over the initial mine life. The mine plan is fairly low in capex requirements with a total planned capital cost of AU$10 million to AU$15 million. Notably, the annual cost of ore haulage from Mt Boppy to Wonawinta plant is AU$6 million to AU$7 million. Thus, the on-site plant will offer significant cost savings and improve the project economics.
Manuka Resources anticipates Mt Boppy to deliver total EBITDA of >AU$90 million and cash flow of >AU$80 million over a five-year mine life.
Wonawinta Silver Mine Project
The Wonawinta silver mine project comprises one mining lease and seven exploration licenses spanning a total area of 920 sq. km. The Wonawinta project hosts a resource of 38.8 Mt @ 42.0 g/t silver, equating to 52.4 Moz contained silver. Within this there is a higher-grade component of 4.5 Mt at 97 g/t silver for 14 Moz silver.
The Wonawinta plant
The Wonawinta project is fully permitted with all the necessary infrastructure, including an 850,000 to 1 million tpa processing plant. The plant has been used for processing ore from Mt Boppy. The Wonawinta silver mine is currently under care and maintenance. The company is considering the possibility of resuming operations at Wonawinta, leveraging the improved silver price environment. Manuka is targeting a mineral resource update for Wonawinta in May 2024 and production by Q1 or Q2 2025.
Taranaki VTM Project
The Taranaki VTM project is located within New Zealand's exclusive economic zone, approximately 22 to 36 kilometres offshore, outside the 12 nautical mile boundary from the coastline. The project boasts a JORC resource of 3.2 billion tons at 10.17 percent iron oxide, 1.03 percent titanium dioxide and 0.05 percent vanadium oxide. It holds a mining license allowing initial extraction of 50 million tons annually, resulting in 5 million tons of VTM concentrate per year for 20 years (concentrate grade of 56 to 57 percent iron, 8.5 percent titanium dioxide and 0.5 percent vanadium pentoxide). At this extraction rate, the JORC resource provides approximately 60 years of potential mining inventory.
The project is anticipated to sit in the lowest quartile of the iron ore production cost curve. The next step for Manuka is to complete a bankable feasibility study on the project.

Kirgella Gift and Providence: First Inferred Mineral Resource Estimate of 76,400 oz Au from only 3m depth
Highlights
- First Inferred Mineral Resource Estimate for Kirgella Gift and Providence of: 2.34 Mt @ 1.0 g/t Au for 76,400 oz at a 0.5 g/t gold cut-off from only 3m depth.
- Gold mineralisation remains open at depth and along strike between Kirgella Gift and Providence:
- Potential for significant resource growth and upgrade following additional drilling to expand on unclassified blocks outside current model limits.
- Highly economic discovery with KalGold’s direct exploration expenditure cost (drilling and assay) of only ~A$4.20 per gold ounce.
- KalGold’s Total Mineral Resource base, comprising this new resource from the Pinjin Project, and the La Mascotte deposit at Bulong Taurus (see ASX: KAL 7th March 2023), now stands at 214,300 oz.
- Elevated gold price of over A$3,600/oz continues to drive interest in mineable gold projects.
KalGold Managing Director and CEO Matt Painter said:
“KalGold is proud to report the first Mineral Resource Estimate at the Kirgella Gift and Providence gold deposits. It totals ~76,000 oz defined at over 1.0 g/t Au from only 3m depth, remains open in several directions, and is considered the first step in defining the full potential of the Kirgella Gift and Providence gold deposits. Pleasingly, we have defined a shallow gold resource at a very low cost to the Company of around A$4.20 per gold ounce.
The Kirgella and Providence mineral resource estimate is comparable to other deposits within the Laverton Tectonic Zone and is considered typical of the region. This is particularly true of some of the constituent deposits at Ramelius Resources’ (ASX:RMS) Rebecca Gold Project, around 20 km to the south along strike.
KalGold now has defined a total resource base of 214,300 oz of gold. The increased resource base enables KalGold to commence high level mining optimisation studies to assess pathways to production. KalGold looks forward to continuing to progress its work in the Pinjin area with the aim of significantly growing this initial JORC Code (2012) resource and defining a suite of additional shallow resources.”
First Gold MRE at KalGold’s Pinjin Project
The Inferred MRE of 2.34 Mt @ 1.0 g/t Au for 76,400 oz Au has been defined at a 0.5 g/t gold cut-off from the Company’s recent drill focus on the shallow portion of the Kirgella Gift and adjacent Providence gold deposits (see Table 1), combined with thoroughly validated historic datasets. Work continues on both deposits, with gold mineralisation open at depth and along strike between the two. This MRE is expected to form the basis of future updates as drilling and exploration continues.

Acquisition of Mubende Gold Project, Uganda
HIGHLIGHTS
- The granted exploration license EL00379 covers 202 square kilometres in the Mubende region west of Kampala and includes the highly prospective Bukuya prospect.
- The Bukuya prospect is currently being mined by 60-80 artisanal workers over 600 metres of prospective strike and remains open along strike and at depth.
- Rock chip samples taken from a recent site visit to the Bukuya prospect by consultant geologists returned numerous specimens containing visible gold in both ferro-manganese and quartz veins.
- Experienced in-country technical team appointed including Mr Dylan le Roux and Mr Allan Agumya to manage exploration activities.
- Field activities scheduled to commence 05 August 2024.
Commenting on the acquisition Managing Director Mr Mathew Walker stated, “We are delighted to have secured a significant land holding that has prospectivity confirmed by a strong presence of artisanal mining activity. Uganda has a well established gold mining industry and regulatory protocols that add to the appeal of the acquisition. We look forward to the commencement of field activities in the immediate term.”
MUBENDE GOLD PROJECT
The Mubende Gold Project is an extensive landholding of 202 square kilometers that covers a series of metasediments, predominantly characterized by meta-wacke’s and phyllitic slates, with occasional interbedded quartzite units and mafic volcanics. Late-stage granites have intruded the metasediments, mainly in the southern part of the license.
Figure 1: Regional Map with locations of Sifang licenses.
At the Bukuya prospect, wall rock consists of metapelitic units with vertical foliation trending NW in most shafts, turning EW in the northern artisanal shafts. Mineralization appears confined to a deformation zone within the metapelites and hosts three subsets of veins exploited by artisanal workers. The first subset includes quartz veins with hematite mineralization, iron-oxide staining, and goethite/limonite-filled vugs, seen in southern shafts with NW trending foliation. The second subset comprises metallic veins of blueish-grey and black ferro-manganese mineralisation with botryoidal textures and specular hematite, found in northern shafts with EW trending foliation. The third set comprises massive milky white quartz veins.
These veins are described in more detail below.
Type 1 (Iron-rich quartz veins): These are quartz veins that show varying degrees of ferro(-manganese) mineralisation. Mineralisation occurs as hematite (red), specular hematite (dark silver/black), and a lesser degree of manganese (botryoidal, blue-grey to black). Vugs filled with limonitic material is often seen in these veins and is interpreted to represent leached out sulphides. These veins are seen in the SE of the Bukuya site. They are typically decimetre to metre scale and are foliation concordant (vertical to subvertical with dominantly NW trend).
