Manuka Resources Limited (ASX:MKR, “Manuka” or the “Company”) is pleased to provide an update on progress of the Company’s Cobar Basin silver and gold production strategy and the restart of the existing 1Mtpa Wonawinta processing plant.
Highlights
- Independent Technical Due Diligence and Legal Due Diligence completed and provided to prospective Financiers.
- Terms Sheets received from multiple parties for the refinancing of existing debt and funding of the Wonawinta Silver Mine restart.
- Silver and Gold prices remain strong with current spot prices increasing the NPV of the Cobar Basin Production Plan to A$153M1.
- Manuka is currently assessing the feasibility of a cut-back of the Mt Boppy open pit (Mineral Resource of 0.4Mt at 4.23g/t Au for 53.5koz Gold)2 to augment and add significant value to the Cobar Basin Production Plan.
Background
Manuka recently released a 10-year production plan based on its 100% owned silver and gold assets located in the prolific Cobar Basin3. The plan comprises the mining and processing of 10.7Mt containing 19.2Moz of silver plus gold credits (Table 1). The Production Target is underpinned by 61% Reserves.
The capital expenditure required to bring the Wonawinta processing plant back into production in Q1 2026 is estimated to be A$18.9M. At an assumed silver price of A$50/oz and average All-In Sustaining Cost of A$35/oz, the project delivers an average EBITDA of A$22M per annum at an IRR of 109% and NPV8 of A$101M.
Financing Progress
The Company advises that it is in discussion with financiers to provide funding to refinance existing debt and bring the Wonawinta processing plant back into production.
Prospective financiers have been provided with independent technical and legal due diligence reports to support their preparation of terms. To date, terms sheets have been received from multiple parties by the Company and are under consideration. The Company aims to reach binding terms on a financing facility early in the third quarter.
The Company further advises that the security shares held by GAM Company Pty Ltd4 have been purchased by existing shareholder and prominent investor Antanas Guoga. The associated convertible notes have been extinguished.
Mt Boppy Gold Mine – Open Pit Cut Back
The Mt Boppy Gold Mine is located 50km east of Cobar and 151km by road to the Wonawinta processing plant. The Mt Boppy Gold Mine comprises an existing open pit with a Resources of 0.4Mt at 4.23g/t Au and a collection of mineralised rock dumps and tailings totaling 2.2Mt at 0.84g/t Au (Table 2). Approximately 0.2Mt from the rock dumps and tailings (less than10%) is included in the Cobar Basin production plan.
Historically one of New South Wales richest gold mines, Mt Boppy is estimated to have produced ~500,000 ounces of gold at ~15g/t Au. The existing open pit was last mined by Manuka in 2021 when ore grading >4g/t Au was extracted and hauled to Wonawinta for processing. Production was halted after a severe weather event caused flooding in the pit and instability in the pit wall.
The Company is currently undertaking a re-optimisation and reassessment of open pit designs to determine the feasibility of recovering the approximately 53.5koz of gold contained in the existing In Ground Resource. The In Ground Resource remains open at depth and along strike and is prospective for mineralisation of the tenor historical mined at Mt Boppy.
The Company aims to report on the result of the re-optimisation and reassessment of Mt Boppy Gold Mine open pit cut back during the upcoming quarter.
MKR Executive Chairman commented:
“Following the release of our updated Cobar Basin production plan, we have moved rapidly to enter into productive discussions with a number of prospective funders for our development strategy. With technical and legal due diligence reports now complete we are confident of securing a financing facility in the upcoming quarter and bringing Wonawinta back into production in the new year.
In parallel, we are progressing a study on a cut-back at the Mt Boppy Gold Mine. With an in-situ gold grade of over 4g/t, the open pit cut back opportunity presents as a potentially high margin gold operation that will augment, and add significant value to, our Cobar Basin production plan.
We look forward to providing further updates to the market on our financing progress and Cobar Basin production strategy in the near future, along with our plans for the re- optimisation of the Mt Boppy Gold Project.”

Manuka Resources
Investor Insight
Manuka Resources’ unique value proposition is focused on its three fully licenced projects, which include two precious metals assets in one of Australia’s most prolific regions for base and precious metals, and a company-making iron sands (vanadium and titanium co-products) project in New Zealand’s exclusive economic zone (EEZ) off the Taranaki bight. Manuka Resources is well-placed to deliver significant shareholder value, driven by a phased strategy that includes a clear pathway to near-term precious metals production.
Strategy Overview
Manuka Resources (ASX:MKR) is focused on bringing its precious metals assets in the Cobar Basin into production, as well as progressing its New Zealand domiciled Taranaki VTM iron sands project.
The company previously revealed a phased strategy focused on delivering maximum value to its shareholders. The first phase focused on bringing back the Mt Boppy gold mine into production and it released an optimised production plan for the mine restart. At the time, the company believed silver production would follow gold but noted it was flexible in this regard. In any event and simultaneous to this, will be the ongoing development of the Taranaki vanadium titano-magnetite (VTM) project.
The Cobar Basin located in the central-west of New South Wales, is one of the richest mining provinces in Australia, home to some of Australia’s largest mining companies and explorers.
The Mt Boppy gold mine was historically one of the richest in NSW, Australia and produced ~500,000 oz gold at an average grade of 15 grams per ton (g/t) gold. Accordingly, the company is very excited about its exploration potential.
Drone image looking South showing the main components of the Rock Dump and tailing resources in relation to the Mt. Boppy open pit.
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 had been processing these wastes from June 2023 to December 2023 at its Wonawinta plant and now will look to optimize the process.
The Wonawinta silver project will be the largest primary silver producer in Australia and expected to be back in silver production within 12 months. Manuka has released a maiden ore reserve (under its ownership) of 4.8Mt1 at 53.8g/t silver containing 8.4Moz of silver comprising proven ore reserves of 0.8Mt at 50.8g/t silver; and probable ore reserves of 4.1Mt at 54.3g/t silver. Ore Reserve is based solely on shallow (<40m deep) oxide material.
The Wonawinta 100tph Ball Mill
The gold and silver market appears to be in an upward trend, with prices for both precious metals hitting their all-time highs recently, in Australian dollar terms for silver, which bodes very positively for MKR.
Company Highlights
- Manuka Resources is an ASX-listed mining company focused on producing gold and silver from its two 100 percent owned fully permitted projects (one gold and one silver) in the Cobar Basin in New South Wales, Australia.
- In addition, MKR’s wholly owned subsidiary Trans-Tasman Resources Limited (“TTR”) is the owner of the Taranaki VTM (vanadiferous titanomagnetite) iron sands project, located in the New Zealand EEZ, off the south-west coast of the north island.
- Manuka released the details of the Taranaki VTM project’s pre-feasibility study (PFS) on 26 March 2025, which highlights the extremely robust economics of the project with an NPV10 of US$1.2B and IRR 39 percent
- TTR will also be lodging its application under New Zealand’s Fast Track Approvals Act for the Taranaki VTM project imminently. (The project was included in Schedule 2 of the Act). Successful conclusion of review under the Fast Track pathway will result in final regulatory approvals (marine discharge consent) being granted, completing the full suite of consents to operate the project for 20 years.
- The Company’s primary focus for its precious metals assets is on bringing both the fully permitted Wonawinta silver project and the Mt Boppy gold mine back into production during 2025. The Wonawinta processing plant (primarily constructed for silver production in 2012 with production capacity of 850,000-1 million tpa) has been recently used for both gold and silver processing and is on active care and maintenance for rapid restart..
- The Wonawinta silver project was previously the largest primary producer of silver in Australia, and Manuka expects this to again be the case once production restarts.
- While the substantially higher gold prices have been securing headlines over the past six months, it is worth noting that the silver price is also trading at an all time high which makes restarting the project very attractive (the all time high for silver is against the Australian dollar, currently silver is around AU$54/oz silver).
- Manuka released its maiden silver reserve in October 2024 making it the only production ready silver reserve on a project based in Australia.
- Elevated gold and silver prices should materially benefit Manuka Resources, resulting in strong profitability and cash flows once its projects move into production.
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.
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.
An 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 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 has released a maiden ore reserve (under its ownership):
- Ore Reserve of 4.8 Mt at 53.8 g/t silver containing 8.4 Moz of silver comprising:
- Proved Ore Reserves of 0.8 Mt at 50.8 g/t silver; and
- Probable Ore Reserves of 4.1 Mt at 54.3 g/t Ag.
The maiden silver ore reserve and the preparation of an implementation plan for Wonawinta support the potential restart of silver mining and processing operations in the near
future. The company is reviewing its silver restart plans in light of the current price increases and expects to announce a decision before the end of May 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 was included in the New Zealand government's Schedule 2 of the Fast Track Approvals Act 2024. The next step for Manuka was to complete pre-feasibility study (“PFS”) on the project. This was released to the market on 26 March 2025 and presents an extremely robust economic outlook for the project as can be seen below.

Wide Gold Intercepts at Mt York Support Future Resource Growth
Three diamond drill rigs on site at 1.4Moz Mt York Gold Project, WA, with 56% of Stage 1 resource drilling complete; Results extend mineralisation along strike and at depth; good continuity of higher-grade shoots confirms new structural model
Kairos Minerals Ltd (ASX:KAI) (“KAI” or the “Company”) is pleased to announce results from the first 16 diamond holes drilled at its Mt York Gold Project in WA’s Pilbara, where current resources at the Main Trend sit at 1.4Moz Au. The results are from Gossan Hill (7 holes), Breccia Hill (5 holes) and Main Hill (4 holes) (Table 1), and are shown on drill plan (Figure 1) and long-section (Figure 2).
Highlights
- 36 holes for 10,025m completed at Mt York, ahead of schedule and on-budget; Stage 1 is an 80-hole, 18,000m resource expansion program
- Results for 16 holes received, with best intercepts including:
- 21m @ 1.87 g/t Au from 169m incl 9m @ 3.19 g/t Au (25MYDD009);
- 5m @ 4.26 g/t Au from 299m (25MYDD010);
- 34m @ 0.81 g/t Au from 242m incl 7m @ 2.66 g/t Au from 269m (25MYDD012);
- 24m @ 1.17 g/t Au from 222m incl 7m @ 2.62 g/t Au from 222m (25MYDD016);
- 48m @ 1.03 g/t Au from 227m incl 11m @ 3.38 g/t Au from 264m (25MYDD017).
- Higher-grade mineralisation consistently reported across Main Trend confirming and extending high-grade shoots at all prospects
- Encouraging first results likely to positively impact grades and widths of mineralisation for an updated resource estimate later in 2025
- Drilling accelerated with third diamond drill rig capable of low-angle drilling on site at the highly prospective but under-drilled Main Hill Prospect
Stage 1 drilling aims to boost gold resources at Mt York and test extensions of high- grade shoots ahead of a mineral resource estimate (MRE) update expected in 2H CY25. Stage 2 drilling later in the year or early 2026 aims to convert Inferred resources to higher confidence Indicated resources.
Kairos Managing Director Dr Peter Turner said: “The first results from Mt York continue to reinforce our belief in the potential scale of this project, and we are on track to deliver a new and much improved mineral resource estimate later in 2025 incorporating at least 18,000m of additional drilling results. We continue to ask ourselves ‘how big is the Mt York gold resource’ and will increase and expand Stage 1 drilling if we believe the mineralisation continues to be open which appears to be the case at the moment.
We are seeing good widths of mineralisation in areas where the resource model is unguided and importantly, solid higher-grade gold intercepts within the lower-grade envelopes. From the previous 2023 resource, Mt York has more than 750,000 ounces of gold at 1.6 g/t Au and the current drilling is confirming that high-grade shoots are both horizontal within the system, but also likely to be extensive (>300m) along-strike in both footwall and hangingwall positions. This is great news.
We are drilling the western half of the large Main Hill Prospect where the mineralised banded iron formation (BIF) host rocks attain 100m in true thickness but where topographic challenges previously prevented drilling. With a suitable small-footprint rig now in place, we can see an assemblage of sulphide-bearing BIF in many drill holes in this area that is associated with free-milling gold mineralisation in other parts of the Main Trend.
With drilling scheduled to continue into September and possibly beyond, we look forward to releasing results as they become available.
We are confident Mt York will become one of the Pilbara’s (and Western Australia’s) largest undeveloped gold resources with clean metallurgy once drilling is complete.”
Drill Results
Results from the first 16 holes are shown in Table 1. The Stage 1 drill holes have been designed to test the grades and widths of mineralisation and purposely looking for extensions of higher-grade pods within the entire 3,000m-long Main Trend Gold Deposit. The positions of the drill holes and their results are shown on Figure 1 (plan view) & Figure 2 (long-section).
Holes 25MYDD007 to 25MYDD009 test gaps in the resource model at Breccia Hill and confirm multiple zones of mineralisation, where 25MYDD009 returned high-grade core of 9m @ 3.19 g/t Au from 176m. This confirms the extension of a high-grade pod of mineralisation some 75m away from historic drillhole KMYD040’s result of 10m @ 4.90 g/t Au from 257m1, that confirms that higher-grade mineralisation may well form significant, horizontal zones previously not recognised yet confirmed in recent structural interpretation.
Deeper drilling into the eastern side of Main Hill has infilled and extended mineralisation with holes 25MYDD010, 012, 014 and 017. Big gains in both mineralisation width and grade are captured in hole 25MYDD017 that intercepted multiple zones including 48m @ 1.03 g/t Au from 227m including a higher-grade zone of 11m @ 3.38 g/t Au from 264m. This extends a new zone of high-grade mineralisation on the footwall position and forms part of the horizontal-plunging, high-grade zone drilled >300m to the west in hole 25MYDD012 (7m @ 2.66 g/t Au from 269m) extending to 25MYDD010 (5m @ 4.26 g/t Au from 299m) (see Figure 2). Another 5 drillholes are planned to the west of these holes to test the extension of the high-grade mineralisation for a further 500m to the west (Figure 1).
The results of the mineralised intercepts are considered close to true widths as the mineralisation has been intercepted orthogonally.
A third diamond drill rig (DDH1 drill rig #83) capable of low-angle drilling has been sent to site to accelerate the program, especially at the poorly tested but prospective Main Hill Prospect. Historic drill results of 109m @ 2.09 g/t Au from 50m (MYD24A) entirely in banded iron formation (BIF) host rocks demonstrate the importance of this prospect. The mineralised banded iron formation (BIF) rocks are the thickest (~100m true thickness) in the area but due to the topographic and access challenges around the hill, the Main Hill target has, until now, been inaccessible for drill rigs.
Holes 25MYDD001-006 are largely testing the mineralised banded iron formation (BIF) on the extreme eastern end of the Main Trend at Gossan Hill.
Rig #83 is drilling the Main Hill Prospect extensively from both the northern and southern sides of the hill (see Photo 2) to truly understand the scale of the resource in this area. There is plenty of evidence that high-grade mineralisation exists at this prospect. Results for these holes (25MYDD023, 028, 031, 032, 033, 034 – see Figure 1 and 2 for location of holes) are awaited.
Further drill results are expected throughout July, August and September and will be released to the ASX once routine quality-assurance, quality-control (QAQC) checks have been completed.

5 Best-performing Gold Stocks on the TSX in 2025
The gold price soared to new record highs during the second quarter of 2025, the most recent coming when it climbed to C$4,663.85, or US$3,433.47, on June 13.
Several factors fueled gold price momentum toward the end of the second quarter, including an escalation in Middle East tensions as Israel and Iran entered into direct conflict. Although a cease fire was announced, it came after the United States dropped several 30,000 pound bombs on key Iranian nuclear sites.
Additional support for gold has come from continued uncertainty in global financial markets as the US's tariff strategy continues.
Since the beginning of the year, investors have sought the relative safety of gold and gold-backed investment products, which have pushed the price up more than 25 percent.
Against that backdrop, which TSX-listed gold stocks have performed the best? The companies listed below have been the top performers this year. Data was retrieved on July 2, 2025, using TradingView's stock screener. Only companies with market capitalizations greater than C$50 million are included.
1. Belo Sun (TSX:BSX)
Year-to-date gain: 276.47 percent
Market cap: C$144.68 million
Share price: C$0.32
Belo Sun Mining is an exploration and development company focused on advancing its Volta Grande gold project in Brazil.
The property covers approximately 2,400 hectares within the Tres Palmeiras greenstone belt in Pará State, Brazil. The company has been working on the project since 2003, and acquired necessary development permits in 2014 and 2017.
A 2015 mineral reserve estimate demonstrated a proven and probable reserve of 3.79 million ounces of gold from 116 million metric tons of ore with an average gold grade of 1.02 per metric ton (g/t).
Development at the site stalled in 2018 after a federal judge ruled that the Federal Brazilian Institute of the Environment (IBAMA) would be the competent authority for issuing environmental permits. The decision was overturned in 2019, with the Secretariat of Environment and Sustainability of the State of Pará (SEMAS) reassuming its permitting authority. The decision was once again reversed in September 2023, returning authority to IBAMA.
On January 23, Belo Sun announced that the Federal Court of Appeals had reassigned SEMAS as the permitting authority for the Volta Grande project. The company said it was pleased with the decision, as the agency is familiar with the project and enjoys a constructive and transparent relationship with it.
The most recent news came on June 23, when the company announced that shareholders had approved a renewal of the company’s governance structure and elected four new directors to the board. Four of the board's six members are now either Brazilian or have spent significant parts of their careers working in Brazil.
Shares in Belo Sun reached a year-to-date high of C$0.35 on June 16.
2. Euro Sun Mining (TSX:ESM)
Year-to-date gain: 200 percent
Market cap: C$53.71 million
Share price: C$0.135
Euro Sun Mining is a development-stage company advancing its Rovina Valley copper-gold project in Romania. The project’s mining license received full approval for 20 years in 2018, with the option to renew it in five year increments.
An updated feasibility study from March 2022 demonstrated the project's economics, showing a post-tax net present value of US$512 million and an internal rate of return of 20.5 percent, assuming a base case gold price of US$1,675 per ounce and a copper price of US$3.75 per pound.
Proven and probable mineral reserve estimates for the site include 1.84 million ounces of gold and 197,522 metric tons of copper from 123.3 million metric tons of ore with an average grade of 0.47 g/t gold and 0.16 percent copper.
Shares in Euro Sun saw their most significant gains around the same time as a March 25 announcement that the EU included Rovina Valley on its first list of strategic assets. The inclusion, which Euro Sun applied for in May 2024, will enable the company to expedite permitting at Rovina Valley and shorten the development timeline.
On May 7, Euro Sun reported it met with Romania’s Minister of the Environment to discuss the advancement of the project. Both parties agreed that a single point of contact was needed to ensure compliance and fulfill requirements under the CRMA framework. The company plans to submit an updated environmental act in the near future.
On June 20, Euro Sun reported it signed a copper concentrates prepayment facility for up to US$200 million with private metals trader Trafigura, with the funding going towards the necessary permitting and investment to advance Rovina over the next 18 months.
Shares in Euro Sun reached a year-to-date high of C$0.145 on June 2.
3. Collective Mining (TSX:CNL)
Year-to-date gain: 165.05 percent
Market cap: C$1.26 billion
Share price: C$15.85
Collective Mining is a gold, copper and silver exploration company with focused interests in Caldas, Colombia.
Its two projects, Guayabales and San Antonio, consolidate large portions of a mineral belt that surrounds Aris Mining's (TSX:ARIS,NYSE:ARMN)Marmato mine and within a region with 10 operating mines.
The Guayabales project comprises 26 claims spanning a total area of 4,780.98 hectares. Collective Mining has conducted extensive exploration at the property in 2025, with a primary focus on expanding the Apollo zone. The company also drilled multiple look-alike targets.
The most recent exploration report was released on June 30, when the company announced the discovery of a new high-grade vein system, with a highlighted assay of 534 g/t gold over 0.67 meters. However, the company stated that drilling was retargeted after results from a gravimetric survey indicated that the drill hole was outside the mineralized breccia body.
On June 23, Collective accelerated its agreement to acquire a 100 percent stake in the Guayabales property. Under the original agreement, Collective had until 2032 to make the required payments and incur the necessary exploration expenditures.
The company reported that the financial considerations remained the same under the amended agreement, but C$2 million would be paid immediately, with an additional C$2 million paid within one month of the title transfer request being filed and C$2.3 million after two months. The remaining C$3.5 million will now be paid out in six equal installments over a three-year period from the date of the amended agreement.
Shares in Collective Mining reached a year-to-date high of C$15.85 on July 2.
4. Starcore International (TSX:SAM)
Year-to-date gain: 150 percent
Market cap: C$19.06 million
Share price: C$0.325
Starcore International is a gold exploration and mining company with assets in Mexico, Canada and Côte d’Ivoire. Its primary asset is the San Martin mine in Queretaro, Mexico.
In the company’s fourth-quarter production results, released on May 13, it reported reaching a significant commissioning milestone in the new processing circuit and milling 5,000 metric tons of stockpiled ore.
The mine produced 3,242 gold-equivalent ounces during the quarter, up 3 percent from 2,268 ounces during the previous quarter. The company added that it was continuing to explore and develop a new area in the southern section of the mine.
Outside its Mexican operations, the main focus throughout 2025 has been its Kimoukro gold project in Côte d’Ivoire.
On April 9, Starcore reported results from 2024 exploration work at the project and an update on its activities at the project. In 2024, the company completed 55 line kilometers of induced polarization geophysical and ground magnetic surveying, along with a 355 hole, 2,988 meter auger drilling campaign.
Based on the results from the drilling, which aimed to confirm an identified gold anomaly in the topsoil, the anomaly is about 2.5 kilometers long and 500 to 800 meters wide, with an average grade of more than 20 parts per billion gold.
In the update, Starcore reported it established a field office during Q1 2025 and is completing a soil sampling program covering 5.5 square kilometers and 1,300 samples up to a depth of 1 meter.
Shares in Starcore reached a year-to-date high of C$0.325 on June 4.

Troilus Gold is advancing its namesake property in Northern Québec, Canada.
The project is situated within the region covered by Plan Nord, a 25 year, C$80 billion development initiative focused on mining launched by the Government of Québec.
A May 2024 feasibility study revealed financials with a post-tax net present value of US$884.5 million, an internal rate of return of 14 percent and a payback period of 5.7 years based on a gold price of US$1,975 per ounce.
The included mineral resource estimate reports a probable mineral reserve of 6.02 million ounces of gold from 380 million metric tons of ore at an average grade of 0.49 g/t gold. It also hosts probable copper and silver reserves of 484 million pounds and 12.15 million ounces respectively.
Troilus has spent much of 2025 raising funds for the project's development. The most significant came on March 13, when the company announced that it executed a mandate letter for a non-binding term sheet for a debt financing package of up to US$700 million.
The company noted that it had followed up on four letters of intent, resulting in a total potential funding of up to US$1.3 billion.
More recently, Troilus announced on June 18 that it had entered into an offtake agreement for gold-copper concentrate with German smelting company Aurubis (OTC Pink:AIAGF,XETRA:NDA).
The agreement is being executed in connection with the previously announced letter of intent for US$700 million in funding. According to Troilus, this includes a loan guarantee of up to US$500 million from a firm representing the German Federal Ministry of Economic Affairs and Climate Action.
Shares in Troilus reached a year-to-date high of C$0.73 on June 17.
