Midnight Sun Mining Corp (MMA)

Posted on behalf of Midnight Sun Mining - The catalyst at the 100%-owned Dumbwa copper deposit in Zambia's Solwezi district is Phase One, expected to conclude in Q3 2026 with about 12,500 metres of drilling left (MMA.v, MDNGF). It is designed to test an initial 11.5 km strike extent using widely spaced fences to define both the higher-grade core and the broader system.

The June 29 release pushed continuous near-surface sulphide copper mineralization to 6.7 km of strike, up from 5.3 km, across 260-plus holes and 56,855 metres with five rigs turning. Recent work added 1.4 km of strike to the north, and the higher-grade core of the Dumbwa shear zone re-emerged beyond a corridor where grade had previously attenuated.

New intercepts: DBW-26-200 returned 21.64 m at 0.42% copper from near surface, DBW-26-165 cut 13.67 m at 0.51% copper, and DBW-26-150 returned 25 m at 0.38% copper.

The stated goal is to define the southern half of Dumbwa and position the system for an initial resource (no NI 43-101 resource yet). Mineralization remains open along the copper-in-soil anomaly, east and west in select areas, and at depth. This is against copper around US$6.25 a pound.

Posted on behalf of Midnight Sun Mining - Today's results push the flagship Dumbwa copper deposit in Zambia's Solwezi district to 6.7 km of continuous near-surface sulphide copper mineralization, up from 5.3 km (MMA.v, MDNGF). Midnight Sun is 100% owner after exiting the KoBold earn-in.

Drilling has now passed 260 holes and 56,855 metres, with this release covering 77 holes. Five rigs continue expanding northward along strike and laterally east and west. CEO Al Fabbro says the team has demonstrated a system at least 6.7 km long and 600 metres to 1 km wide.

Latest intercepts: DBW-26-200 returned 21.64 m at 0.42% copper from near surface, DBW-26-165 cut 13.67 m at 0.51% copper, and DBW-26-150 returned 25 m at 0.38% copper.

On the drill geometry: Dumbwa has a high-grade central corridor 100 to 600 metres wide within a broader shell exceeding 1,000 metres. The grid is built around that. Discovery holes sit 50 to 100 metres apart on each east-west line, with only two or three in the high-grade core per section. The rest deliberately test the lower-grade margins, because proving full width and continuity means drilling to the edges, not just chasing the richest centre.

Copper is trading around $6.18 a pound. Dumbwa sits in the Zambia-Congo Copperbelt, the world's second-largest copper-producing region, near the geologically similar Lumwana mine and First Quantum's Kansanshi. The company will host a technical webinar with COO Dr. Kevin Bonel to discuss these results. The system stays open along strike and at depth, setting up the methodical case toward a first resource. See the June 29, 2026 news release for the full assay table.

In a recent video interview, VP Adrian O'Brien laid out where all the drilling at the flagship Dumbwa discovery in Zambia is heading: a first resource. MMA.v, MDNGF is now 100% owner after exiting the KoBold earn-in.

The stated goal is to define the extents of the southern ~12 km half of Dumbwa by the end of 2026, positioning for an initial mineral resource estimate. O'Brien framed that southern half as a 1 to 1.5 billion tonne exploration target (not a defined resource).

What's drilled so far: 5.3 km of continuous mineralized strike within a 20+ km copper-in-soil anomaly peaking around 0.73% Cu at surface. Over 200 holes and more than 42,000 m, with assays in for the first ~4 km. Five rigs run roughly 10,000 m per month on tight 50 m spacing. Mineralization starts at surface and reaches 175 to 220 m deep, some holes past 300 m. Recent intercepts include 93 m at 0.40% Cu, plus earlier hits like 1.0% Cu over 22 m (see the May 13, 2026 news release).

On funding: roughly C$35M in treasury after the C$30.5M financing in late 2025, enough to carry the southern program. The Solwezi address is flanked by First Quantum's Kansanshi and Barrick's Lumwana, the latter a geological analogue. Copper sits around $6 a pound into a structurally tight market.

O'Brien's full walkthrough of the resource pathway is here:

Posted on behalf of Midnight Sun Mining (TSXV: MMA | OTCQB: MDNGF)

Midnight Sun Mining continues to advance its Dumbo copper discovery in Zambia, with management highlighting one of the largest assay releases in the company's history and a growing understanding of the system's scale. The latest program confirms continuity across a large bulk-tonnage copper target, with more than 5 km of drilled strike now defined and drilling continuing across the broader 20 km copper-in-soil anomaly.

Key discussion points from the interview included:
• 99 drill holes released, providing a clearer picture of the Dumbo discovery.
• Over 5 km of drilled strike completed, with drilling continuing toward an 11 km Phase 1 target.
• Fully funded exploration program with approximately C$15M expected to remain after Phase 1.
• Ongoing work to support a future mineral resource estimate when appropriate.
• QA/QC issues have been addressed, with improved assay turnaround expected.
• Four drill rigs remain active as the company systematically expands and refines the discovery.

With drilling continuing, additional assays pending, and a disciplined exploration strategy underway, Midnight Sun remains focused on defining the full scale of its emerging Copperbelt discovery.

The simplest way to read MMA (TSXV: MMA, OTCQX: MDNGF) right now is to look at how it is drilling, not where copper is trading. A recent video interview with VP of Business Development and Communications Adrian O'Brien walks through how the company is delineating its Dumbwa copper discovery in Zambia's Solwezi district, and the pattern is the one a major would use to define a deposit.

The drill program is built for systematic delineation:

- Five rigs turning at roughly 10,000 m per month
- Tight 50 m spacing across the target
- Over 200 holes and more than 42,000 m drilled to date
- 5.3 km of mineralized strike inside a 20+ km copper-in-soil anomaly running to about 0.73% copper at surface
- Open along strike and at depth

What the drill has hit:

- 93 m at 0.40% Cu, 80 m at 0.39% Cu, 44 m at 0.53% Cu, and 36 m at 0.58% Cu (May 13, 2026 NR)
- 1.0% Cu over 22 m (DBW-25-010)
- 0.98% Cu over 15 m (DBW-25-009)
- 0.89% Cu over 25 m, incl. 1.36% Cu over 6 m, within 0.46% Cu over 50 m (DBW-25-021)

Two things let MMA run at this pace. COO Dr. Kevin Bonel, who helped build Barrick's neighbouring Lumwana resource, now leads the work at Dumbwa, which the company frames as a geological analogue to Lumwana. And the balance sheet supports it: a treasury of roughly C$35M following a C$30.5M financing at $1.35 in late 2025, plus 100% ownership of Dumbwa after exiting the KoBold Metals earn-in.

The company has also shown it can carry a target across the line. Its Kazhiba Main oxide copper deposit holds a maiden Indicated resource of 2.33 million tonnes grading 1.41% copper, effective date January 20, 2026.

The near-term goal is concrete: know the extents of the first roughly 12 km, the southern half of Dumbwa, by the end of this year, which would position it for an initial resource estimate on that section. With copper around $6.34 a pound and a funded program, the drill-driven newsflow keeps coming.

O'Brien's full walk-through of the geology and the year-end plan is here:

Posted on behalf of Midnight Sun Mining Corp. - One of the few new district-scale copper discoveries emerging in a world starving for new supply.

Midnight Sun's Dumbwa discovery now extends >5.3km of continuous strike within a 20km+ copper-in-soil anomaly—and remains open in multiple directions.

What stands out:

• 200+ holes, 42,000m+ drilled
• Near-surface copper sulphide system
• 100% owned
• Located between Barrick's Lumwana and First Quantum's Kansanshi mines

Selected results:

• 1.00% Cu over 22m (DBW-25-010)
• 0.98% Cu over 15m (DBW-25-009)
• 0.89% Cu over 25m (DBW-25-021)
• 0.46% Cu over 50m incl. 1.36% Cu over 6m (DBW-25-030)

The key catalyst isn't one drill hole—it's scale.

With 5 rigs turning and ~10,000m/month being drilled, management's goal is to define the first 12km of Dumbwa by year-end.

So far, step-outs are extending the system rather than closing it.

In a $6+ copper environment, new large-scale discoveries are rare. That's why the second half of 2026 could be particularly important for $MMA.

A recent presentation from VP of Business Development and Communications Adrian O'Brien is worth a look if you follow the copper juniors. He walked investors through Midnight Sun's (TSXV: MMA, OTCQX: MDNGF) flagship Dumbwa copper discovery in Zambia's Solwezi district at Virtual Investor Conferences' Precious Metals & Critical Minerals event.

The backdrop first. Copper is trading around $6.40 a pound, and electrification demand keeps running into a thin pipeline of large new deposits. With a structural deficit intensifying and majors hunting Tier-1 assets, O'Brien used Dumbwa's at-surface, large-tonnage potential as the lens for why a system this size matters.

What has actually been defined:

- Dumbwa now extends more than 5.3 km of continuous strike, open along strike and at depth, inside a 20+ km copper-in-soil anomaly.

- A campaign exceeding 200 holes and 42,000 metres has confirmed a large, near-surface copper sulphide system in the prolific Domes Region, near Kansanshi and Lumwana (May 13, 2026 NR).

- Flanked to the north by First Quantum's Kansanshi mine and west by Barrick's Lumwana mine, with the geology drawing a clear analogue to Lumwana.

- 100% owned after Midnight Sun exited the KoBold Metals earn-in.

On the geology, O'Brien described three main lenses that feather gradually outward, cross-cut by faults creating distinct higher-grade blocks. Drilling is on a tight 50 m grid to build a robust dataset for future resource estimation.

The grade so far:

- 1.0% Cu over 22 m (DBW-25-010) and 0.98% Cu over 15 m (DBW-25-009) (Nov 18, 2025 NR).

- 0.89% Cu over 25 m in DBW-25-021, plus 0.46% Cu over 50 m in DBW-25-030, including a higher-grade interval of 1.36% over 6 m (Jan 29, 2026 NR).

What I am watching: five rigs running at about 10,000 metres per month, year-round. The stated goal is to know the extents of the initial 12 km of Dumbwa, the first half of the system, by the end of 2026.

With each step-out so far extending the system rather than closing it, the back half of 2026 sets up as a steady stream of results that could keep filling in the scale of what Dumbwa really is. The full geological picture is in the presentation.

A major structural supply deficit is hitting the copper market, with Scotiabank recently noting that "the copper market is tighter than you think" due to rising green-tech demand clashing with a 49% drop in global mining growth capex.

This looming supply squeeze places a massive premium on scalable new discoveries, positioning Midnight Sun Mining as it rapidly defines a district-scale copper system in Zambia's prolific Domes Region.

The company’s flagship Dumbwa deposit is a massive, near-surface sulphide copper system modeled directly after Barrick’s adjacent 1.6-billion-tonne Lumwana mine. With multiple rigs actively turning, the team has completed over 42,000 meters of drilling, extending Dumbwa's drilled strike length past 5.3 kilometers, which remains wide open.

Recent public filings reveal substantial insider accumulation from Midnight Sun Mining director and senior officer, Brett Allan Richards.

Throughout the first half of June 2026, Richards deployed over $760,000 of personal capital to acquire 852,603 shares in the open market. These transactions were executed at prices ranging between $0.805 and $0.94 per share, significantly increasing his position.

By stepping up with significant personal capital at these levels, Richards provides a clear validation of the company's valuation and strategic direction, particularly as intensive definition drilling continues to expand the Dumbwa copper project in Zambia.

Posted on behalf of Midnight Sun Mining Corp. - MMA.v; MDNGF

After a run of interviews and presentations, Midnight Sun is fully funded with over $31 million in the treasury, and executing a rapid, two-pronged development strategy to unlock district-scale value:

Expanding Dumbwa: Rigs are actively drilling 6,000 to 10,000 meters per month to map out the southern corridor of the Dumbwa deposit. The drilled strike length already exceeds 5.3 kilometers, and the team aims to complete definition of this initial 11.2-kilometer copper-in-soil trend by Q3 2026. The project serves as a direct geological analogue to Barrick’s nearby 1.6-billion-tonne Lumwana mine.

Monetizing Kazhiba Main: Following a high-grade maiden resource estimate at Kazhiba Main, management is actively negotiating to monetize the asset. The goal is to leverage this near-surface oxide deposit to fully fund continuous drilling at Dumbwa without diluting shareholders.

Looking ahead, Midnight Sun is uniquely positioned with a clear pathway to non-dilutive capital, fully funding its push to define Zambia's newest large-scale copper system just as global demand peaks.

During a recent OTC Markets Group Virtual Investor Conference, Midnight Sun Mining VP of Business Development Adrian O'Brien walked through a comprehensive corporate presentation, highlighting the company's massive copper opportunity in Zambia.

Key insights and highlights from the presentation include:

- The Ultimate Copper Jurisdiction: O'Brien explained why Zambia is currently the most globally important region for copper exploration, noting that the country derives 75% of its export earnings from copper and boasts a highly supportive, pro-mining government.
- Surrounded by Giants: The company's project is located in the "domes region" of the Zambian Copper Belt, positioning them squarely in the center of the five largest copper mines in Africa, which all feature massive, low-capex, at-surface deposits.
- The Dumbwa Discovery: Midnight Sun has made the first major copper discovery in the belt in 22 years at its flagship Dumbwa target. The team has already drilled 5.3 kilometres of strike length, confirming a large-scale system that rivals the physical footprint of neighboring billion-tonne deposits.
- Aggressive Value Creation: Leveraging extremely low local drilling costs of roughly $160 per metre, the company currently has five drill rigs turning to complete 6,000 to 10,000 metres per month. The goal is to aggressively build the scale of the Dumbwa discovery before entertaining any future M&A scenarios.

Posted on behalf of Midnight Sun Mining Corp. - MMA.v; MDNGF

Midnight Sun Mining Corp. recently released its Q1 2026 Management's Discussion and Analysis, highlighting a uniquely strong operational position across its Zambian copper assets.

Critical takeaways from the report:

Rapid Scale at Dumbwa: The wholly owned Dumbwa deposit has officially transitioned into a large-scale discovery, with over 42,000 metres of drilling confirming near-surface copper sulphide mineralization over a massive 5.3-kilometre strike length. Four active rigs continue to expand the deposit laterally and along strike, making upcoming assay results a major catalyst to watch.

Fully Funded Capital Position: Midnight Sun has eliminated near-term dilution risk by entering the period with $26.19 million in cash and $24.96 million in working capital following a major $30.48 million financing. Management confirmed this treasury is fully sufficient to fund all corporate and exploration costs over the next fiscal year without seeking additional equity.

Low Risk Monetization Pathway: The company delivered a maiden Indicated resource at the Kazhiba Main Oxide deposit of 2.33 million tonnes grading 1.41% copper. Because Kazhiba sits less than 10 kilometres from First Quantum's Kansanshi mill and is part of a cooperative exploration plan, it provides a direct, low-cost path to commercialization without requiring standalone infrastructure.

"We have a massive discovery on our hands," says Midnight Sun Mining VP Adrian O’Brien.

In a recent MSE interview, O’Brien detailed how the company has successfully defined a continuous copper mineralized zone across 5.3km of its massive 20km Dumbwa target in Zambia’s Copperbelt.

Following the release of assays from 99 drill holes, the results confirm that Dumbwa is a "geologically identical" analog to Barrick’s nearby 1.6-billion-tonne Lumwana mine.

Benefiting from exceptionally low drilling costs of ~$160/m, Midnight Sun has four rigs systematically advancing to test the first 11km of strike by the end of Q3.

Additionally, the company is moving to monetize its near-surface Kazhiba oxide resource to fund the ongoing Dumbwa expansion entirely non-dilutively.

In a recent technical webinar, Midnight Sun Mining Vice President Adrian O'Brien and COO Dr. Kevin Bonel provided an in-depth update on the massive scale and strategic upside of the company's flagship Dumbwa copper discovery in Zambia.

The presentation highlighted several major catalysts and defining characteristics that position Dumbwa as a globally significant copper asset:
- A "Perfect Storm" for M&A: Dumbwa is centrally located in the prolific Domes Region, surrounded by giant producing mines from Barrick, First Quantum, and Ivanhoe. Sitting directly between newly funded, competing US and Chinese rail corridors, the asset is generating intense global strategic interest.
- District-Scale Growth: Following over 46,000 metres of drilling, the team has confirmed a continuous, near-surface copper sulphide system spanning 6.25 kilometres. With four rigs turning, Midnight Sun is aggressively advancing to test the anomaly's full 11.5-kilometre extent.
- The Lumwana Analogue: Dr. Bonel noted that Dumbwa is geologically "indistinguishable" from Barrick's neighbouring billion-tonne Lumwana mine. It exhibits the exact same basement-hosted geology, with comparable grades and thick, flat-lying geometry ideal for low-cost open-pit mining.
- Fully Funded for Expansion: Benefitting from exceptionally low regional drilling costs of roughly $160 per metre, Midnight Sun is well-capitalized with $25 million in cash. This ensures the massive Phase 1 drill program will be completed by late summer as the project advances toward an initial resource estimate.

Posted on behalf of Midnight Sun Mining Corp. - Midnight Sun Mining Delivers Major De-Risking at Dumbwa Copper Discovery


(TSXV: MMA | OTCQX: MDNGF) has delivered a pivotal de-risking milestone at its Dumbwa copper discovery in Zambia, releasing assay results from 99 drill holes in one of the largest single-batch updates by a junior explorer this year .

The results materially advance Dumbwa from early-stage target to a confirmed, large-scale copper system in the heart of the Zambian Copperbelt — a district that hosts operations such as Barrick’s Lumwana, First Quantum’s Kansanshi, and Ivanhoe’s Kamoa-Kakula .

Scale and Continuity Now Demonstrated

• Assays now confirm mineralization across ~5.3 km of strike within the broader 11+ km Phase 1 focus area .

• The system is shaping up as a large-tonnage, bulk-mineable copper deposit with zoned grade distribution .

• Geological similarities to Lumwana are pronounced, including stacked sulphide lenses and comparable structural controls .

Management emphasized that the drilling grid — 50m across strike and 100–200m along strike — is intentionally systematic, designed to build a defensible dataset for eventual resource work .

Disciplined Execution, Strong Funding

Four rigs are currently active on the southern 11 km corridor , with competitive drilling costs (~C$160/m all-in) enhancing capital efficiency . The company expects to retain approximately C$15 million in treasury following Phase 1 completion , providing runway toward a potential maiden resource in late 2026 or early 2027 .

Dumbwa sits within a 20 km copper-in-soil anomaly — only partially tested — in one of the world’s most productive copper provinces. In an environment where large-scale copper discoveries are increasingly scarce, a growing system in an infrastructure-rich belt commands attention.

The thesis is straightforward:

- Scale is emerging.

- Continuity is being demonstrated.

- Geological analogues are proven.

- Funding is secure.

For investors seeking exposure to copper discovery leverage in a tier-one district, Midnight Sun’s Dumbwa system has entered a new phase of credibility and momentum.

Midnight Sun Mining has released the latest assay results from its ongoing drill program at the Dumbwa copper deposit in Zambia.

Based on the new data, the company reports that continuous, near-surface copper sulphide mineralization has now been traced over a 5.3-kilometre strike length.

Among the many results reported, the top drill highlights included 93 metres grading 0.40% copper, 80 metres at 0.39% copper, and a near-surface 44 metres at 0.53% copper. These results continue to inform the company's geological model, which compares the structural controls of the Dumbwa system to the nearby Lumwana mine.

To date, Midnight Sun has completed over 42,000 metres of drilling across roughly 200 holes. The company currently has four drill rigs operating on site, with the primary objective of testing the northern strike extension and defining the eastern and western boundaries of the known mineralization.

Additionally, quality control issues related to laboratory analysis have been resolved, and the related backlog of assays are now largely caught up.

The Company plans to host a technical webinar with COO, Dr. Kevin Bonel, to discuss the results announced in this news release.

As copper prices near all-time highs, Midnight Sun Mining is aggressively advancing its exploration portfolio to meet an unprecedented wave of future demand.

Midnight Sun is drilling the Dumbwa target in the heart of Zambia's prolific Domes Region. Dumbwa is a large-scale, near-surface sulphide copper system that shares striking geological similarities to Barrick's neighboring world-class Lumwana mine.

Copper has already gained 9.3% for the year, and analysts note that data center infrastructure and the energy transition are all set to significantly outpace the growth projected for core economic uses.

To rapidly delineate what could be Zambia's next major copper discovery, the company is executing a systematic drill program at an impressive rate of 10,000 metres per month.

This aggressive campaign is designed to fully define the first 12 kilometres of Dumbwa's massive 20-kilometre copper-in-soil anomaly by Q3 2026. With over 35,000 metres already drilled and rigs actively turning, investors can look forward to a steady flow of highly anticipated drill results in the near term.

Posted on behalf of Midnight Sun Mining - MMA.v; MDNGF In a recent interview at PDAC 2026, Midnight Sun Mining discussed its transition from discovery to resource definition. The company is actively navigating a dual-track strategy to balance aggressive exploration at its massive Dumbwa target while working to monetize the newly announced Kazhiba oxide resource.

Key Highlights
- Massive Scale Discovery: The Dumbwa target represents a staggeringly large 20-kilometer mineralized system, which the company equates to the entire length of Manhattan from Battery Park to Harlem.
- Methodical Execution: Taking advantage of highly favorable $160/meter drill costs in Zambia, Midnight Sun is fully funded to systematically drill off the first 12 kilometers of the target on tight 50-meter by 100-meter spacing by July.
- The Lumwana Analog: COO Kevin Bonel notes that Dumbwa's stacked geological model is identical to the neighboring Lumwana mine (which Barrick acquired for $7.3 billion), but Dumbwa features an anomaly nearly five times the strike length.
- Self-Funded Growth: The company recently published an MRE for its near-surface Kazhiba Main oxide deposit and has now opened the doors to monetize the asset, intending to use the cash to fully fund the ongoing Dumbwa exploration without diluting shareholders.

By leveraging cost-effective drilling and a clear strategy to self-fund its exploration, Midnight Sun is methodically building an undeniable dataset for what could be the next tier-one copper acquisition in Zambia.

For more on Midnight Sun & the progress at Dumbwa, here’s a recent interview with their VP Communications Adrian O’ Brien from the PDAC:

Posted on behalf of Midnight Sun Copepr Corp. - Zambia is stepping up its push to become a global copper powerhouse.

The country is actively courting international investment — including from the United States — as it targets tripling copper production to ~3 million tonnes per year by 2031.

Key context:

• 2024 production: ~890,000 tonnes (below the 1Mt target)

• Strategic metal: copper is critical for EVs, power grids, and renewable energy infrastructure

• Zambia also hosts significant cobalt, nickel, manganese, lithium, graphite, and rare earth elements

With China currently dominating much of the global critical minerals supply chain, Zambia is increasingly viewed as a strategic partner for Western supply diversification.

The government has emphasized that new investment must deliver “win-win” outcomes for both Zambia and investors, signaling a pro-development stance as it seeks capital to unlock its mineral wealth.

Against this backdrop, exploration companies operating in the region are gaining attention.

Midnight Sun Mining (TSXV: MMA | OTCQX: MDNGF) continues advancing its copper portfolio in Zambia’s Domes Region, filing the NI 43-101 Technical Report for the Kazhiba Main oxide copper resource while aggressively drilling the Dumbwa discovery target.

Highlights:

• 20-km copper soil anomaly at Dumbwa, with values reported up to 73% Cu in soil

• Grid drilling underway (~10,000 m/month) with ~4 km of strike already tested

• Kazhiba oxide resource potentially providing a non-dilutive funding pathway

• Located near major operations such as Barrick’s Lumwana

With major infrastructure development, geopolitical competition for copper supply, and growing investor interest, Zambia is rapidly emerging as one of the most important exploration frontiers for the next generation of large copper discoveries.
