Redcastle reports 144,800t stockpile resource and $1.097m cash

6,600 Ounces Stockpiled but Still Awaiting a Mill

Redcastle Resources Ltd (ASX:RC1) has gold sitting on its ROM pad, but no clear processing route yet. The company reported a JORC 2012 Mineral Resource of 144,800 dry tonnes at 1.43 g/t gold for 6,600 ounces as at 31 August, including 4,300 ounces at 2.75 g/t in the high-grade stockpile.

Redcastle Reef accounts for 6,500 ounces of the estimate, with Queen Alexandra contributing a further 100 ounces from limited mining in its highly weathered upper profile. The stockpiles were reported as ready for transport, but they are not Ore Reserves: contained gold is not recovered gold or revenue, and conversion depends on treatment arrangements plus further technical and economic assessment. The inventory was previously quantified in the company’s September stockpile resource announcement, which said processing negotiations remained unresolved.

Third-Party Tolling Deferral Stops Mining

Mining continued at Redcastle Reef through July and August, with initial work also starting at Queen Alexandra, about 700 metres to the west. The planned third-party toll-treatment pathway was then deferred, prompting the Redcastle-BML Ventures Joint Venture to suspend mining from close of business on 31 August while it assessed alternative milling options.

BML Ventures, the joint venture operator, is funding mining and working capital through to first revenues, with net proceeds after agreed joint-venture costs shared equally between BML and Redcastle. That structure limits Redcastle’s upfront project funding exposure, but it does not remove the immediate dependency on a commercially suitable processing solution. The company said the timing of treatment, first revenue and any mining restart remains dependent on securing that arrangement and meeting operational and approval requirements.

Queen Alexandra Grades Support Expansion Case

Queen Alexandra produced another set of strong grade-control results during the quarter, although the results had already been disclosed in earlier announcements rather than reported for the first time in this quarterly document. The latest 127 holes covered 4,449 metres, with 86 holes, or about 68%, returning at least one significant intercept averaging 2.0 g/t gold or more under the company’s stated reporting criteria.

Standout uncut downhole intercepts included 2 metres at 37.52 g/t from 37 metres in BMRC476, including 1 metre at 67.70 g/t, as well as 5 metres at 12.47 g/t in BMRC559 and 6 metres at 8.21 g/t in BMRC519. Across the two assay batches, 153 of 265 holes returned at least one significant intercept. The results are intended to sharpen ore-waste definition, dilution control and short-term scheduling when field operations resume. As with the earlier Queen Alexandra assay results, true widths have not been established and grades are uncut.

New Lease Removes a Tenure Constraint

Redcastle also executed a Native Title and Mining Agreement with the Wangkatja Tjungula Aboriginal Corporation RNTBC, acting for the Nyalpa Pirniku Native Title Holders. The agreement covers relevant granted and pending tenements, including M39/1171, and followed an extended engagement process. It builds on the earlier Native Title agreement linked to the Queen Alexandra expansion area.

Mining Lease M39/1171 was granted effective 1 September and sits immediately south of the existing M39/318 lease. It gives the joint venture room to assess a larger Queen Alexandra pit and further southern grade-control drilling, but any expansion remains subject to an amendment to the current Mining Development and Closure Proposal. That approval work, like the processing solution, is unfinished.

Cash Runway Adds Pressure to the Processing Decision

Redcastle ended the quarter with $1.097 million in cash, down from $1.763 million at the start of the period. Operating cash use was $347,000, exploration and evaluation expenditure was $363,000, and the company reported $45,000 of equity proceeds. On the reported expenditure measure, that left an estimated 1.54 quarters of funding, with no unused financing facilities disclosed.

Redcastle said it had not started a funding process but would assess its requirements as circumstances evolve. The next material milestone is therefore not another headline drill result. It is whether the company can secure a mill, restart mining and turn the stockpiled resource into processed ounces before cash and approval timelines become the more pressing constraints.
