"Leading the discovery and expansion of the Rhosgobel gold-tungsten deposit at Sitka Gold's RC Gold Project in Yukon"

Geologist

Biography

Mike Burke is a professional geologist serving as Chief Geologist and Director at Sitka Gold Corp, where he leads exploration at the company's flagship RC Gold Project in Yukon, Canada. With deep expertise in Carlin-type gold systems and orogenic gold deposits, Burke has been instrumental in building Sitka Gold's resource base from early-stage exploration through to a substantial multi-million-ounce gold inventory. His technical leadership has positioned the RC Gold Project as one of the more significant emerging gold stories in the Yukon's prolific Tombstone Gold Belt.

Burke's most notable achievement at Sitka Gold has been the systematic advancement of the Rhosgobel deposit, where he oversaw the expansion of the mineral resource estimate to 5.12 million ounces of gold (1.29 Moz indicated and 3.83 Moz inferred). His geological insight led to the recognition that tungsten mineralization, in the form of tungsten trioxide (WO₃), is pervasive throughout the deposit. By initiating the re-assaying of approximately 5,500 samples from 33 drill holes, Burke quantified significant tungsten concentrations across roughly 850 meters of strike, with impressive intercepts including 128.0m of 0.115% WO₃ and 152.3m of 0.109% WO₃. This work resulted in the official addition of tungsten and silver to the Rhosgobel resource estimate, with 51,345 tonnes of WO₃ and 2,926,000 ounces of silver now included alongside the gold inventory.

The tungsten by-product potential that Burke identified adds a compelling economic dimension to the Rhosgobel deposit. Initial metallurgical testing demonstrated an average gold recovery of 94.3% through conventional cyanidation and 84.7% tungsten recovery in rougher concentrate via flotation, suggesting that tungsten could serve as a meaningful by-product credit in a potential future open-pit operation. This kind of multi-commodity resource optimization reflects Burke's ability to extract additional value from complex mineral systems that more conventional exploration approaches might overlook.

Under Burke's technical direction, Sitka Gold has maintained an aggressive exploration pace with a 60,000-meter diamond drill program utilizing four rigs at the RC Gold Project. His work has drawn attention from the mining investment community, with appearances on platforms such as the Korelin Economics Report and GOLDINVEST to discuss resource developments. For mining stock investors, Burke represents the type of technically rigorous exploration geologist whose geological interpretation and systematic approach to resource definition can materially impact a junior mining company's valuation trajectory.

Sitka Gold - High-Grade Gold Results At Blackjack, Saddle & Eiger, RC Gold Project, Yukon

Sitka Gold - High-Grade Gold Results At Blackjack, Saddle & Eiger, RC Gold Project, Yukon

guest Sep 22, 2026
  • Top takeaway Argues that deep hole 133 at Blackjack (141.5m of ~2 g/t Au incl. 80m at 3.2 g/t and 6m at ~10 g/t) confirms the deposit continues at depth and exceeds the 2 g/t grade bar needed for an underground resource
  • Sees the 13-hole saddle zone program as filling the 550m gap east toward Eiger, with mineralized material currently classified as waste likely to be brought into the updated mineral resource estimate targeted for early 2027
  • Says the 60,000m program is about 50,000m complete on seven rigs with roughly 50-60 holes still pending and a late-October wrap; frames Roskalpa as the largest near-surface ounces available, with Blackjack, Saddle and Eiger all still growing

Sitka Gold's headline hole 133 returned 141.5m at ~2 g/t gold, including 80m at 3.2 g/t, pushing Blackjack's deep mineralization above underground thresholds. Saddle zone step-out drilling traced mineralization 550m east from Blackjack toward Eiger, reclassifying previously modeled waste rock into the upcoming resource estimate. Lamprophyre dikes and intrusive corridors link Blackjack, Saddle, and Eiger into one continuous mineralized system; management expects the three pits to merge. Seven rigs remain active across the 60,000m program with roughly 50-60 holes pending assays, and an updated mineral resource is targeted for early 2027. Blackjack sits at about 2.3 million ounces (indicated plus inferred) at roughly 1 g/t gold, while drilling also targets Rhosgobel, Pukelman, and Bearpaw Breccia.

Sitka Gold - Expanding the Rhosgobel Gold and Tungsten Footprint at the RC Gold Project

guest Sep 9, 2026
  • Top takeaway Burke argues that the Rhosgobel deposit is far from defined and that ongoing drilling will continue to expand it along strike and at depth, calling it a 'real cornerstone near surface open pit deposit' driving project economics.
  • He is interpreting small north-northwest structural offsets intersecting the main east-west trend, which he says will guide drilling east and west of the deposit to avoid missing the main zone at its edges.
  • He maintains the focus is on near-surface open-pit mineralization, with current holes reaching 300-400m depths, and explicitly contrasts this with Blackjack where the deepest hole has reached 1.1 km.
  • He frames tungsten as a promising value-add byproduct that Sitka will incorporate into future economic studies, noting it shares the same veining as the gold mineralization.
  • He outlines a deliberate sequencing — grow the deposit size first, then move into infill drilling to lift resource confidence by year-end, especially in the higher-grade >1 g/t near-surface eastern zone.

Hole 71 at Rhosgobel returned 159m of 1.14 g/t gold within 257m of 0.84 g/t gold, validating a north-northwest structural theory. The deposit remains open in every direction: strike now spans 1.6 km, with step-out holes extending mineralization over 100m below the prior resource shell. Scheelite (a tungsten mineral) sits within the same gold-bearing quartz veins, potentially providing a meaningful economic byproduct credit. Seven drill rigs are turning across six targets at the RC Gold Project, with 43,000 of a planned 60,000 meters already complete this season. Burke frames Rhosgobel as a cornerstone open-pit deposit; the team is growing resource size first, then upgrading inferred ounces into higher confidence categories.

Sitka Gold - Court Approves 100% Acquisition of Clear Creek Property & 7-Drill Exploration Update

Sitka Gold - Court Approves 100% Acquisition of Clear Creek Property & 7-Drill Exploration Update

guest Aug 20, 2026
  • Top takeaway Mike argues that locking in 100% ownership of Clear Creek via the cash-only $6M payment sends a clear message that Sitka is 'pretty excited' about the property.
  • He pitches the Ross Gobble deposit (2.25M oz and growing) as a 'huge part' of the project and says they still don't know how big the deposit is.
  • He frames the 5% NSR buy-down to 2% for $10M as 'a bit of a steal of a deal' and calls Sitka's right of first refusal on the royalty a 'valuable piece' of the deal.
  • He says seven drills are turning across the property — blackjack/saddle/eiger gap, Rauch-Aubel, Pukoman contact, and Bearpaw — and credits a well-oiled field team for keeping up with core volumes.
  • He acknowledges assay results are 'trickling in' and says the labs are overwhelmed, partly because Sitka itself just added a seventh drill and partly because 2026 looks like a record-breaking drilling year in the Yukon.

Court approval on Aug 18, 2026 cleared Sitka's accelerated $6M cash purchase of Clear Creek, locking in 100% ownership of the RC Gold Project. Sitka holds well over $10M in cash after recent warrant exercises, funding the $6M Clear Creek payment in cash rather than shares. Clear Creek carries a 5% NSR royalty reducible to 2% for $10M; Sitka also holds a right of first refusal on any sale. Sitka is running seven drills across a 60,000m program covering Rhosgobel, Pukelman contact, Bearpaw, Eiger, and Saddle targets. Lab capacity is stretched by record-breaking Yukon drilling volume, slowing assay turnaround despite steady news flow expected into year-end.

Sitka Gold - Drill Results: High-Grade Results, Underground Potential & Active 7-Rig Program

guest Aug 12, 2026
  • Top takeaway Frames hole 132 — drilled along the eastern margin and below the Blackjack deposit — as evidence the deposit is expanding and as a strong signal for potential underground-resource mineralization at depth, contingent on hitting enough drilling density by the end of 2026
  • Argues that hitting roughly 3.8 g/t over 44m at about 600m depth within a multi-phase intrusive at the bottom of hole 132 is geologically meaningful, noting the system is intersecting mineralized metasiments between intrusive dikes deep down
  • Reads hole 129's 118m at 0.5 g/t (including 32m at 1.4 g/t) east of Blackjack as an expansionary step toward Saddle, arguing the east-west dike trend connecting Blackjack, Saddle, and Eiger can be followed and could merge the Blackjack and Saddle pits
  • Outlines near-term catalysts: six rigs turning across Blackjack, Saddle, Eiger, Rosgobble, and Contact-Pukoman with a seventh being mobilized (possibly to Bearpaw Breccia), more than 32,000m drilled, faster assay turnaround, and a goal of producing an additional mineral resource estimate at Contact-Pukoman

Hole 132's deeper, higher-grade intercept (44.4 m of 3.86 g/t gold) supports the case for a future underground resource at Blackjack. Linking Blackjack to the Saddle and Eiger zones via step-out drilling could reclassify waste as resource and lower strip ratios. Deeper, higher-grade mineralization sits outside the current open-pit resource, but converting it requires sufficient drill density. Sitka Gold's 7-rig program has already surpassed 32,000 m, with assays starting to flow more quickly through the labs. Connecting separate deposits into a single continuous mineralized zone could expand mineable inventory across the RC Gold project.

Sitka Gold - 100% Acquisition of Clear Creek & 60,000m Exploration Update

Sitka Gold - 100% Acquisition of Clear Creek & 60,000m Exploration Update

guest Jul 29, 2026
  • Top takeaway Burke frames the Clear Creek acquisition as the 'final piece of the puzzle' for RC Gold, locking in 100% control over the Ross Goble discovery plus the Pukoman Zone and Bearpaw Breccia targets.
  • Burke calls the right of first refusal on the Clear Creek royalty a 'pretty powerful ace to have in your back pocket' that protects Sitka if the receiver moves to sell.
  • Burke highlights the 60,000-meter drill program as the company's main near-term focus, with six rigs active and a seventh being added to maximize meters drilled in 2026.
  • Burke is constructive on near-term news, expecting Roscoable and Blackjack drill results soon, while acknowledging Yukon lab turnaround is slower than ideal.
  • Burke's forward focus is de-risking the project toward a PEA, with a mineral resource update targeted for the coming year.

Sitka Gold accelerated its Clear Creek property acquisition to 100% ownership, paying $6M cash to consolidate the Rhosgobel-bearing claim group. Clear Creek carries a 5% NSR royalty, reducible to 2% via a $10M payment; Sitka also holds right of first refusal on its sale. Sitka is halfway through its 60,000m drill program, with rigs turning at Rhosgobel, Contact Zone, Saddle, Eiger, and Bear Paw Breccia. Yukon lab delays have slowed assay turnaround, but Sitka expects a steady flow of drill results and an updated mineral resource next year.

Sitka Gold- High Grade Dill Results: 164.0 Metres of 1.83 g/t Including 45.0 Metres of 3.49 g/t Gold

Sitka Gold- High Grade Dill Results: 164.0 Metres of 1.83 g/t Including 45.0 Metres of 3.49 g/t Gold

guest Jul 16, 2026
  • Top takeaway Burke's central argument is that Blackjack keeps improving with depth and runs past the point any open pit could follow - the last hole reached 1.1 km down - so he wants the team to define grade and tonnage 300-400 metres below the current pit-constrained resource to test an open-pit-to-underground transition, noting no underground resource has been defined yet.
  • He concedes the near-surface work is the real priority this season: the Saddle zone still sits inside the pit-constrained outline, so converting it into resource would turn what is currently waste into potential ore.
  • He frames hole 128 as a step-out outside the current resource that should add ounces to the mineral resource update planned for early 2027, and calls results of that kind "pretty special".
  • On Rhosgobel he says the early-season holes show a big, wide mineralized envelope with the nicer, higher-grade portions, that the discovery was only drilled in earnest for the first time in 2025, and that the current drilling is step-out work to define the edges before any infilling is considered.
  • He is cautiously positive on tungsten, saying it stays closely associated with the gold intersections and that the metallurgy done so far indicates it looks like a viable byproduct, while more study is still required.

Sitka Gold's Hole 128 at the RC Gold Project returned 164 metres of 1.83 g/t gold, including 45 metres near 3.5 g/t. Grades climbing with depth matter because the deposit outgrows any open pit, pushing Sitka toward an underground mine. The first seven Rhosgobel holes extend mineralization below the current resource, and all of them are step-outs. Tungsten sits consistently alongside gold in core, and metallurgy will decide whether that byproduct is worth recovering. Over 24,000 of a planned 60,000 metres are drilled, and an updated mineral resource estimate is targeted for early 2027.

Sitka Gold ($SIG | $SITKF): Advancing a 5+ Million-Ounce Gold Project in Yukon

Sitka Gold ($SIG | $SITKF): Advancing a 5+ Million-Ounce Gold Project in Yukon

guest Jun 30, 2026
  • Top takeaway Presents RC Gold as hosting over 5 million ounces across two deposits about 5 km apart, Blackjack (1.3 million indicated at roughly 1 g/t plus 1.0 million inferred at 0.94 g/t) and the new Ross discovery (2.25 million inferred at 0.7 g/t), found with only about 59,000 metres of historical drilling.
  • Says the fully funded 60,000-metre 2026 program is about 18,000 metres in with $40 million in the bank, first results just released and new batches due roughly every two weeks into year-end, ahead of an updated resource estimate and preliminary economic study targeted for early Q1 2027.
  • Argues the Ross discovery, outlined from just 12,000 metres and 43 first-pass holes and open in every direction, has potential to double, with 30,000 metres of this year's program aimed at it and early tests showing over 90% gold and 85% tungsten recoveries.
  • Describes a decade of drilling remaining: only 3 of 11 intrusions drilled on the 477-square-kilometre property, each partially drilled intrusion potentially worth around 5 million ounces, and 10 million ounces plus 'not beyond our expectations', with the board motivated to drill rather than sell.
  • Highlights tungsten at Ross (about 51,000 tonnes at 0.051% tungsten trioxide) as a possible byproduct that could support non-dilutive off-take financing, plus underground potential at Blackjack below the pit shell, including a 45-metre intercept at 5 g/t.

Don Durrett argues the gold and silver correction is cyclical, not the end of the bull market, and expects higher highs eventually. Sitka Gold's RC Gold project in the Yukon hosts over 5 million ounces across granite-hosted intrusion-related deposits being expanded by drilling. A 2.25-million-ounce inferred resource at the Rosgobel discovery also carries tungsten and silver byproducts, opening potential non-dilutive financing options. Sitka is fully funded with $40 million in the bank for its 60,000-metre drill program, releasing results every couple of weeks. Don Durrett frames Sitka as an optionality play, valued around $50 an ounce in the ground against a $1.2 billion takeover estimate.

guest Jun 29, 2026
  • Top takeaway Argues the June 23 results show Blackjack keeps expanding, with step-out-designed holes adding ounces both near surface and at depth and open-pit grades still above 1 g/t.
  • Presents a working thesis that structures tighten at depth so about the same amount of gold sits in a narrower, higher-grade zone — explicitly not an epithermal boiling-zone target — which, if right, points to a potential bulk underground mining scenario with long life.
  • Credits oriented-core drilling under VP of exploration Gilles Dessereaux with pinning down the deposit's plunge and structural controls, so the team can consistently follow the higher-grade core of the system at depth.
  • Frames the deep program as input to open-pit vs underground trade-off studies, noting better-than-1 g/t shallow grades should help early capital payback.
  • Expects resources to move well past the current 5+ million ounces, telling the host the same rocks as Fort Knox and the Eagle mine run close to 10 million ounces, with a first resource targeted at the Contact Pukoman and Bearpaw Breccia zones by year-end.

Six new holes blend infill and expansion drilling, hitting better than 1 g/t (grams per tonne) gold, some starting shallow for quicker capital payback. Oriented core shows a structural control that tightens mineralization at depth, guiding deep holes and feeding open-pit versus underground trade-off studies. Visible gold in core confirms drillers are in the right veins in real time, but it does not map one-to-one to assay grades. The guest frames Sitka's 5 million combined ounces against roughly 10 million ounce intrusion-related systems like Fort Knox and Eagle.

Sitka Gold's first 2024 drill hole at RC Gold returned 94.0m of 1.79 g/t Au, including 19.3m of 5.04 g/t Au, demonstrating high-grade mineralization at depth. The significant intercept in hole 121 extends mineralization well below current open-pit boundaries, suggesting strong potential for a future underground mining scenario. The company is actively scaling its massive 60,000-meter drill program across multiple zones, with a steady flow of assay results expected throughout the year.

Sitka Gold - Rhosgobel Discovery Confirmed 1.1KM Of Mineralization, 60,000 Meters Planned in 2026

guest Jan 27, 2026
  • Top takeaway The guest frames Rhosgobel as a potential 'foundational asset' for the RC Gold project and argues that the 1.1 km mineralized strike plus 60,000 m of 2026 drilling will define the true scale of this 'third deposit' on the property
  • He explicitly cautions that the upcoming initial mineral resource estimate (targeted Q1 2026, ahead of PDAC) is just the starting point, emphasizing the system is open in every direction and at depth so subsequent updates should expand the resource
  • On tungsten, he argues it is a significant value-adding byproduct because its spatial distribution does not track gold grade — sometimes the higher tungsten occurs with lower gold — so incorporating tungsten could 'even out' gold-equivalent grade across the deposit; he notes tungsten is a critical mineral and that a tungsten resource would likely follow the gold resource
  • He outlines a methodical exploration strategy: ~100 m step-outs around Rhosgobel in 2026 combined with continued drilling at Blackjack (depth), Saddle, Eiger, the Pukoman contact zone, Bearpaw Breccia, and untested targets along the eastern strike toward the Big Creek Stock
  • On execution, he highlights the project's logistics edge — road access and a mid-February camp opening — with the intent to start the drill by late February or early March 2026 to maximize the season given the 60,000 m program

Rhosgobel mineralization spans the full 1.1-kilometer strike after 43 holes and nearly 13,000 metres of 2025 drilling at Sitka Gold's Yukon RC Gold Project. Sitka Gold plans its maiden mineral resource estimate (MRE — the first official size estimate) for Rhosgobel ahead of PDAC in Q1 2026. Re-assaying 32 holes for tungsten trioxide could add byproduct value and smooth out gold grade, with a separate tungsten resource to follow the gold MRE. The 2026 program targets 60,000 metres starting mid-February, directing about half toward Rhosgobel expansion plus step-outs at Blackjack, Saddle, Eiger, and Pukoman. Rhosgobel remains open in all directions and at depth — the deepest hole cut mineralization at about 400 metres, with 100-metre step-outs planned.

Sitka Gold - Expands RC Gold With New Discoveries, 2026 Major Drilling Plans

Sitka Gold - Expands RC Gold With New Discoveries, 2026 Major Drilling Plans

guest Jan 21, 2026
  • Top takeaway Burke argues the three deposits (Blackjack, Eiger, Rosgobel) form a large connected mineralized system in the Clear Creek Intrusive Complex, and he plans to allocate 10-15,000 metres of the 2026 drill program to follow up on Bearpaw, Contact and Pukleman zones.
  • Burke frames new zones like Contact and Bearpaw as incremental additions to a developing gold base rather than standalone 2-5 million ounce deposits, arguing that near-surface higher-grade ounces could be sequenced early in a future mine plan to lift project economics.
  • Burke sees potential for additional plus-million-ounce discoveries across untested intrusions on the property, including Pukleman, Josephine, and the Big Creek stock soil geochem anomaly.
  • Burke stresses that background de-risking work — baseline environmental, water/wildlife and additional metallurgical studies — is essential to advancing the project toward a PEA.

Blackjack resource more than doubled to over 2M oz at ~1 g/t in 2025 — 1M indicated (drill-defined), 1.2M inferred (early estimate); stock returned 169%. Rhosgobel discovery defines ~1.1 km of mineralized strike at surface with tungsten alongside gold; an initial resource estimate is the next near-term catalyst. Sitka is doubling 2026 drilling to ~60,000 m, with 10-15k metres earmarked for the new Bearpaw, Contact, and Pukelman zones. Treasury of $45M+ covers the program; metallurgical, environmental baseline, and water/wildlife work runs in parallel toward future economic studies. Low drill costs of $350/m CAD reflect the project's two-hour drive from Dawson City's paved-runway airport.

Sitka Gold - Drill Results and 60,000 Meters of Drilling In 2026: Expanding Gold Area By 400 Meters

guest Jan 7, 2026
  • Top takeaway Argues Rosgobel is a 'spectacular new deposit' and likely the largest on the RC Gold Project, but stresses this is only the first year of drilling (about 13,000m so far) with mineralization open in every direction and untested at depth beyond 400m.
  • Plans to deploy the 60,000m 2026 program mostly on Rosgobel to define size potential for a preliminary mineral resource estimate, with the longer-term aim of moving toward a PEA and economic studies on the Clear Creek camp.
  • Frames tungsten (scheelite) as a potentially meaningful credit — gravity-recoverable and consistent with the Tombstone-Tungsten suite — while cautioning that accurate assay techniques are still being worked out before public numbers are released.
  • Frames May Q (southeast target) as a valid large area still in early testing, with first two holes returning only modest grades (best 2m of 0.7 g/t) but enough encouragement to warrant follow-up drilling in 2026.

Rhosgobel now spans ~975m along strike and stays open in every direction after 11 holes added 400m to the mineralized footprint. Sitka plans a fully funded 60,000m 2026 drill program backed by $45M in cash, with all-in drilling near $350/m. Visible scheelite (tungsten) in core hints at a critical-mineral byproduct alongside gold, though assays are still being optimized. Blackjack and Eiger already host ~2.8M oz; the 2026 priority is a maiden mineral resource estimate on Rhosgobel.
