Hannam's note, Feb 2021.
2020 a year of major progress at Havieron JVGreatland Gold (GGP) has been one of the most notable success stories in the junior gold space of recent years, rising from a microcap junior to a company with a market cap of over £1bnat its peak in January 2021. This share price appreciation has been driven by spectacular exploration success at the Havieron project that outlined a world class asset both in terms of grade and scale,within a truckable distance tothe 20Mtpa Telfer mill,hungry for ore. In our view,the market is valuing Greatland Gold shares based on a much larger resourceat Havieronthan the maiden resource announced in December 2020. Drillingresults to date have shown a significant mineralisation footprint, as well as continuity of mineralisation that, in our view, will support a mining operation for several decades suitable for both selective mining in the higher-grade sulphides and bulk mining in the lower grade breccia zones. Thus we have derived a valuation based on extending the life of the sub-level cave(SLC) mine outlined in our previous notes and also modelling a bulk-tonnage, block cave mine at Havieron over 25-year life, which is common for similar operations around the world. Changes to our Havieron DCF model include addition of a block cave.
Our updated Havieron DCF model is based on our internal estimates for capital and operating costs, production rates, metal recoveries and payabilities. While we acknowledge an elevated margin for error in forecasting project parameters ahead of the completion of a scoping or feasibility study, we make our estimates based on an understanding of the deposit as well as our knowledge of economics of SLC and block cave underground mining. We update our SLC model to a 20-year, 2Mtpa operation, with mining commencing in late 2023. Our block cave valuation assumes mining commencing in 2028 with a two year ramp up to 18 mtpa, with the Telfer mill being filled to capacity with a combination of high-grade SLC and low-grade block cave mined ore. We estimate upfront capital costs for the block cave of US$1.5bn, based on our understanding of comparable block cave projects globally. Following the completion of the SLC in 2042, we assume a 20 Mtpa block cave operation untilthe end of the mine-life in 2053.
