Signature Resources (TSX-V:SGU) is taking bold steps to unlock the long-untapped potential of its Lingman Lake Gold Project in northwest Ontario. With a published maiden resource of 769,520 ounces and fresh drilling aimed at extending both depth and strike, the company is positioning itself to prove the project’s scale can reach 2–3 million ounces.
Backed by promising metallurgical results and a 32km greenstone belt of targets, Signature is working to transform an 80-year-old discovery into a modern gold growth story.
CEO Dan Denbow says that the Lingman Lake project is 80 years in the making, with advanced exploration completed in the late 1930s and early 1940s until it closed in 1946, mostly due to inflation and costs.
“In every gold cycle, every 10 or 20 years, it seems like as the gold price comes up, exploration comes back to the property,” Denbow says.
Signature Resources published its maiden resource estimate (MRE) in July 2025 for Lingman Lake, outlining the above-mentioned 769,520 ounces. Denbow notes that the initial resource does not include the historic exploration data, as the company did not have the necessary core to prove or retest the resource. However, they did have around 43,000m of drilling from the 1980s and then from 2016 that went into the MRE.
The company’s work to date at the site covers around 2km worth of strike, across the 32km-wide greenstone belt, and Denbow notes that there are a lot of other areas within the envelope that the company needs to look at.
“Lingman Lake may not be the best deposit on our property, it’s just the one where all the work has been done, so that’s where we’ve been focused so far.”
Lingman Lake: Stepping out beyond the pit
The maiden MRE for Lingman Lake includes 95,200 ounces of gold at 1.38 grams per tonne indicated and 674,320 ounces of gold at 1.14 g/t gold inferred, with the company now focused on resource expansion.
Signature recently completed its winter drill program of around 4,000m, which focused on extending the resource at depth and laterally, using 3D induced polarisation (IP) studies to target extensions.
“We know that this thing is open at depth. We’re only really down to about 250m of drilling at the moment, and then we’re trying to explore out to the west,” Denbow says.
Denbow notes that the pit that was designed in the MRE was around 1.6km in length, and the company is now focused on drilling to the west to extend it another 600m.
On the eastern side of the property, Signature is doubling its depth to approximately 500–600m.
“This is real exploration,” Denbow says.
“We could have gone back and added ounces just by infill drilling and tightening up our spacing, but we really wanted to step out and see what it looks like from a wider perspective.”
Unlocking a 32km belt
Denbow explains that most of the company’s exploration work to date has been focused on the main property itself.
Signature has 12–13 targets across the 32km land package, with Denbow noting that with the folding and faulting across the land, the company can see how the targets stretch out to the west of the main site, and where the best targets are along the trend.
A regional wildfire in 2022 led to the loss of some of the company’s drill core, but it did clear a lot of the brush from the property, making it easier to see the main structures, outcroppings, and mineralisation from the air.
Historical work from the 1980s identified the two main targets through trenching. Denbow says that Signature now needs to go back, reopen those trenches, and get them mapped out a bit better.
Denbow has a full plan of operations for exploration outside of Lingman Lake once Signature is ready to do so.
“The next step would be to do more fieldwork, where we go out and do channel sampling, grab sampling, and mapping of these targets, which we’ve prioritised based on prior geophysical work,” Denbow says.
“Then, we would like to take some geologists, put them out in the field, map it, do some channel sampling of surface expressions of the structures, and then from there we would design a drill program.”
While there are no plans for fieldwork outside of Lingman Lake at the moment, Denbow says that Signature’s main focus is to take the 769,000 ounces from the initial resource and prove that it could be 2–3 million ounces.
“Our current drilling is not enough to do that, and even our next drill program wouldn’t be enough to get to a resource of 3 million ounces, but we would be able to paint a picture that shows of Lingman Lake, that this goes deeper, this goes laterally to the west, and that it has the potential to continue and expand out from Lingman Lake.”
Before this work begins, though, Signature is awaiting the drill results from its winter drill program, which will likely take until the end of June 2026.
“With that done, then we can look and see what we’ve learned from this drilling, then go back to investors and tell them what the next steps are.”
Recoveries tell a story
The other key focus for Signature at the moment is the gold deportment and mineralogical study completed earlier in 2026 by SGS Canada. Denbow notes that the results have started to show what recoveries look like and what the process is to get the recoveries.
As previously reported, the study outlines that gold occurs primarily as free milling gold and gold-silver alloys within the ‘high-grade’ part of the system, with the majority of gold grains either exposed or partially exposed, which the company notes indicates beneficial processing characteristics.
“The biggest highlight from the study was the low concurrence of arsenopyrite,” Denbow says.
“It showed no problems, or any problems with recovery. We’ve got 92–96% recoveries, and we would assume that when we take the grinding size down, we could probably increase our recoveries even more.
“It did not take a lot of work to get the gold liberated and most of it was liberated without any troubled molecules, so it was a very good study for us and we’re incredibly pleased with the results.”
Proving scale in a tight capital market
As Denbow mentions, exploration has come back to the site again and again in good gold markets and today is no different. Signature is well positioned with its considerable land package to build on the current gold price momentum.
That said, Denbow sees a different kind of gold market than what he has seen historically.
“Typically, when you see the gold price move like it has, you would see a lot more speculation in the bottom end of the early exploration market, and you would see these companies trading at much higher valuations because they were going to be the next big projects,” Denbow says.
“You would also see the majors out there chasing these projects and a lot more M&A. We’ve seen M&A on the production side, but not a tonne of activity at the speculative end, [or] the early exploration.”
So, while the gold price is up, we’re not seeing as much interest in the bottom end of the exploration side, with less money coming into the space than expected.
In Canada specifically, Denbow notes that the retail speculative money has been burned recently by the cannabis and lithium markets several years ago, both of which didn’t deliver the returns that were expected.
“The Canadian speculative money isn’t there like it used to be. A lot of companies as well are more cautious than they’ve been in the past and have been focused on cash flow and things like buybacks and dividends, instead of doing the exploration work.”
For Signature, the absence of that speculative market is less a setback than an opening. It’s a chance to prove ounces in the ground, while the majors and investors wait for the next growth story to emerge.
Drill results first, growth next
Getting the rest of the drill results from the recent winter program is the company’s immediate priority, because, as Denbow explains, “that’s going to tell us what we found at depth”.
The company is also assessing the value of its 3D IP study, picking out key takeaways and how useful they are before starting to work towards the metallurgical study.
That study, however, is still several months away.
“So really, the next two and a half months are going to be all about these drill results, getting the assays back from the lab, figuring out what our analysis is, what our key takeaways are, and then we can look at planning that next drill program,” Denbow says.
Funding is another key consideration and Denbow stresses the company’s valuation gap.
“I think we’re very undervalued for a company that has 762,000 ounces in a published resource,” Denbow says.
“We think we can show you how that 762,000 ounces is really a million ounces or more when you factor in infill drilling and expanding the length of the pit.”
Signature’s ownership of its own rigs is a key differentiator in this market.
“We control our own destiny because we own our own rigs.”
This means that Signature can drill whenever they have the rigs and the company isn’t paying a premium to use them.
For Signature Resources, the story at Lingman Lake is about more than ounces on paper. It’s about proving scale, demonstrating recoveries, and showing investors that disciplined exploration can unlock growth in today’s cautious gold market.
With 769,000 ounces already defined, rigs in hand, and a 32km belt of targets still to be tested, the company is positioning itself to turn an 80-year-old discovery into a modern gold growth story.
