Thanks very much, [uncertain]. Change gears a bit now to resources for a number of years, and he's going to give us Marc Ducler.
Yeah, thanks very much, Nicholas. I'm old as three-quarters of the audience here. When I was here, my presentation was going to focus on four key items. Today's intro one. Here we go. The resource growth and the cost of those 2.8 million ounces at Nampaman and Mandilla. [audio distortion]. The cost of that resource growth last cost [audio distortion] announced. Items three and four were actually to do with [uncertain] and was AUD 5,500. It's actually still [audio distortion] not. I'm now on the [audio distortion] in June of this year. We resolve those complexities and we'll [audio distortion] of next [audio distortion]. Remains a crack mine that will be operating for decades. I'll update you on Astral, [audio distortion] our mining ounces that we have in resources. They're actually [audio distortion]. This is a premier jurisdiction investing in 17 [uncertain] study. At [uncertain], which are [uncertain], we are in the bank.
We are working on fund. It's going to generate some additional cash flow for us expenditure at Mandilla. Mandilla will be a long recent diamond additional growth, and we have [audio distortion] and Mandilla [audio distortion] and given our location, permanent is a [audio distortion] and also Donald started to drop [audio distortion] on the gold [audio distortion] back to those and even though the price are still [audio distortion] peer group 100,000-ounce per annum production profile and compelling value with gold. Then you look closer, got a 1 g/t ore body at Bullabulling, [audio distortion] from awesome development opportunities. One in value of Mandilla. Something takes debt and it takes equity.
With a cashed-up miner, I will all need to fund our [audio distortion]. There's a little bit of has the potential million dollars in the of next year and be in revenue in the free cash produce. Now we understand how to run a cost, how to build Egan Street and importantly, it was explored, fully permitted delivered here at best perspective. I would love. These are the pre. We and we used AUD 4,250 for the price is [uncertain] . Development is [uncertain] . This is a very solid project with fancy located on Feysville is as we're reviewing those now. We on the Mandilla mineral resource on the mineral ending a very [audio distortion]. We are working through the detailed mining collect for our [audio distortion]. Once that's finalized, that allows us to submit an enclosure n ext year. That should be all in the measured decision.
Acknowledge [audio distortion] company, but we are looking to mitigate with Think Big, which on the [audio distortion] in the next drill felt that this deposit was open at depth and test underneath it. It's shown logged visible gold. This diamond program has hit see the potential, and we're now focused on just under extension from [audio distortion] that you can see on. This first section type of mineralization returns [uncertain] at 1.2 g/t, and then another [uncertain] . Second hole there you can see returned an to mineral down-hole depth. Still for one of the holes is at 4.5 m. The second hole you can see right-hand side trace it, and also for gold to extend to [audio distortion]. Again, the mineralization is [audio distortion]. It's actually [audio distortion]. That's a problem for us to resolve in 10 years now is about mining Theia. This shows the blue drill column ending inside stage one.
The [audio distortion] pit start dry. Processing. We're halfway through the half by 12.5 m drill density. This average [uncertain] at 1.1 g/ t. This is [uncertain] . Other project Think Big completed a heritage survey at Kamperman and diamond drilling Kamperman quarter of [uncertain]. Also, in the process of updating the mineral resource December quarter. To Feysville, we announced the Feysville deposit's a satellite Mandilla pre- forward gold price. Think Big has the potential cashflow and you [audio distortion]. The mine proposal and [audio distortion] is RC is at 7 m at 12 g/t, 9 m at 6 g/t, et cetera. To shape up project we bought off Maximus last year [uncertain] called the Spiders. We're actually estimates for the Spiders, [uncertain] get that out. [Uncertain] nest where we propose to build the Mandilla process significant. [audio distortion]. The Theia infill will continue [audio distortion].
Spargoville and Kamperman will [audio distortion]. We will recon December quarter of next year, and that will be in revenue [audio distortion] much as well. To wrap this all up, the Mandilla Gold Project and [uncertain] and our [audio distortion] we have AUD 650 million and the [audio distortion] as we [audio distortion].
Thanks very much.
