Days after dual listing on AIM, the company said Kasiya could generate average earnings of $161 million per annum on an EBITDA basis. The internal rate of return on the investment is 36%.

In terms of rutile pricing, Sovereign is using $1346/t as the 25-year life-of-mine average, with forecasts by industry expert TZMI in 2022 being about $1500/t for the bulk market and $2000/t for the bagged market.

Kasiya's output is targeted to be 60% to the bulk market and the balance to the bagged market, while operating costs - which take into account Kasiya's production of a graphite byproduct - are put at an average of $352/t.

Annual production is put at 122,000t of rutile and 80,000t of graphite, with the latter's pricing put at $1085/t. 

Sovereign claims the "revenue-to-cash cost ratio of 2.8-times and the average annual revenue to capital cost ratio positions Kasiya in the first quartile compared to other undeveloped mineral sands operations".

In terms of environmental bona fides, Sovereign points to its natural rutile's inherently low carbon footprint, plus the proposed use of hydro and solar power.

Sovereign is now set to work on upgrading the resource and updating scoping work in mid-2022.

The company had nearly A$6 million cash at the start of the current quarter.

Sovereign is listed on ASX but also debuted on the AIM on Tuesday.

Shares in the company jumped 7.9% on Thursday to 34p.
