Haranga hits the Mother Lode reset button at Lincoln

Haranga Resources has put some proper numbers behind the revival story at its Lincoln Gold Project in California, with the first Lincoln-Comet diamond drilling program in more than 12 years returning a string of bonanza-grade gold hits and, just as importantly, feeding into a maiden JORC-compliant resource expected in mid-May.

The headline assays are not the sort that need much gilding. The better intersections include 4.8m at 25.40g/t gold from 36.4m in DDH0278, including 2.4m at 48.84g/t; 2.4m at 38.01g/t from 26.3m in DDH0274; 9.2m at 9.58g/t from 1m in DDH0279, including 0.6m at 69.1g/t; and 4.5m at 18.74g/t from surface in DDH0285. There were plenty more where those came from, including 2.5m at 29.94g/t from surface in DDH0286 and 5.9m at 13.13g/t from 37.3m in DDH0267.

For investors, the key point is not just that Lincoln is high grade. That was already the historical selling point. The issue is whether Haranga can drag a legacy Canadian NI 43-101 estimate into the ASX world of JORC compliance, while demonstrating there is still enough geological plumbing beneath the old workings to support a bigger story.

The JORC conversion looms large

Lincoln-Comet and Medean currently carry a foreign, non-JORC estimate of 958,910 tonnes at 9.29g/t gold for about 286,000 ounces, using a 4.2g/t cut-off. Haranga’s completed 3,250m HQ diamond program was designed to provide the drilling density, lode geometry and validation data needed for a maiden JORC Mineral Resource Estimate. The company says only four holes from XC8 remained outstanding, with those assays expected this week, and the resource targeted for mid-May.

That makes the next fortnight unusually important. A JORC resource will give the market a more conventional yardstick for valuing Lincoln, rather than leaning on historical and foreign estimates. Haranga also intends to report the resource at multiple cut-off grades, including a formal 2.0g/t cut-off. With spot gold trading around US$4,606 an ounce on Monday, the company’s view that a lower cut-off could be relevant is not being made in a hostile gold market.

Depth repeats: still early, but useful

The sexy assays are near existing underground access, but the strategically interesting part of the release may be the deeper holes DDH0280 and DDH0281. These were drilled from XC7 to test whether the Comet system repeats at depth.

They did not return spectacular grades, with DDH0280 producing 2.2m at 1.2g/t gold from 172.1m and DDH0281 returning 2.2m at 1.38g/t from 149.4m. But they intersected alteration, veining, silicification and sulphide mineralisation more than 150m below the current decline. In plain English: the system is still alive down there, even if the drill bit has not yet hit the sweet spot.

Chairman Michael Davy said the program had “confirmed the very high-grade character of the deposit” while also establishing a stronger technical base for resource growth drilling at depth. He added that the deeper drilling confirmed the system remained “wide open at depth”, with parallel repetitions of the shear zones that host the quartz-gold lodes.

Infrastructure gives Lincoln a different flavour

Lincoln is not a greenfields paddock with a few shiny assays and a dream. Haranga says about $90m of prior capital has gone into the project, including a 315,000 tonne per annum processing plant, an 880m underground decline, 900m of development drives, workshops, offices and key mining permits.

That infrastructure does not remove development risk, but it changes the conversation. The company is already dewatering at maximum permitted rates, with a planned pause in drilling to re-establish power, ventilation and communications to the lower decline. The underground rig is expected back in July for further drilling below XC8.

What investors should watch next

Haranga ended the March quarter with $9.3m cash, giving it some room to advance the near-term work program without immediately rattling the tin. Recent market data showed HAR trading around 14c, with market capitalisation estimates around $58m to $60m, keeping it firmly in speculative small-cap territory rather than producer-land.

The coming catalysts are clear enough: remaining XC8 assays, the Lincoln-Comet and Medean JORC resource, a Medean exploration target, then deeper and targeted drilling from July. The existing South Spring Hill exploration target of 1.16Mt to 1.64Mt at 5.4g/t to 5.8g/t for 202,000 to 308,000 ounces also underlines the broader growth pitch, though it remains conceptual rather than a resource.

For now, Haranga has done what small gold developers must do: produce high-grade hits, add geological confidence and keep the news train moving. The next question is whether the maiden JORC resource gives investors something solid enough to hang the Lincoln restart story on.
