Killi Resources Limited (ASX: KLI) has hit a promising stride with the first drilling results from its maiden campaign at the Mt Rawdon West Project in Queensland. The Kaa Prospect, where these results were obtained, could be shaping up as a large-scale gold-copper system—potentially a new epithermal discovery in the making.
In its latest ASX release, Killi revealed assays from the first three diamond drill holes, with promising indications that a significant mineralised system is at play. These holes mark the first ever drilled at the prospect, which sits within a 1.8 km gold-copper-silver trend. Importantly, the system remains open in all directions, signalling plenty of exploration upside.
Visible mineralisation in these drill cores, including sulphide-bearing quartz veins and copper minerals like chalcopyrite and malachite, strongly suggests that Killi has tapped into a large epithermal system. This early-stage exploration could open the door to a significant gold-copper discovery if further drilling continues to deliver.
One of the standout aspects of the results is the broad zones of alteration seen in the drill holes. Killi reported intervals up to 150 metres wide of potassic and silica alteration, often indicative of hydrothermal fluid movement—a key marker for epithermal systems. CEO Kathryn Cutler highlighted this point, noting that these results align with what the company expected from surface sampling, and they are "on track" to uncover a significant system.
The company also noted that mineralisation appears to intensify towards the south-eastern end of the trend, providing a "vector" for future drilling targets. Surface rock chips from this area returned eye-catching grades of up to 238 g/t Au, 2.1% Cu, and 513 g/t Ag.
The assays, though preliminary, show promise, and the confirmation of wide alteration zones strengthens the case that Kaa could be part of a much larger system. With Queensland’s reputation as a mining-friendly jurisdiction, and Killi’s proactive exploration strategy, this is a stock worth keeping an eye on as they move into the next phase of drilling.
Killi is waiting on assays from three additional holes, with results expected in November. Once in hand, these results will guide the next phase of exploration, with more drilling planned to vector in on the source of the gold and copper mineralisation. In parallel, the company recently completed an Induced Polarisation (IP) survey at the nearby Baloo prospect, a copper-gold-molybdenum anomaly spanning 2.4 km by 1.7 km, with results due soon.
Armed with these findings, Killi is well-placed to extend its drilling program at Kaa and potentially launch exploration at Baloo. The company remains well-funded for these initiatives, and with the Mt Rawdon Gold Mine—one of Evolution Mining’s key assets—just 8 km away, the area is undeniably prospective for further discoveries.
As Cutler aptly put it, the team is "excited" by the initial developments—and with assays pending and more drilling on the horizon, the anticipation is building. Investors will be watching closely to see if Killi can unlock a significant new discovery in the coming months.
