Ann: Half Year Accounts - December 2021, page-19

if you qualify the 53 RC campaign, it is roughly 1700 x 600m @ 100m spacing.
I estimate the total cost to be roughly $250-300k of expenditure (53 holes x 40-50m depth x $120 per metre)
If you look at our M&I resource is 160Mt @ 0.56% Ni 0.09% Co, achieved over roughly 4000m x 2000m
If you pro-rate this to the 1700x600m area you achieve roughly 50Mt @ 0.56% Ni 0.09% Co
If you discount the 50Mt due to some duster holes perhaps you could say 30Mt - 40Mt of additional laterite resource for $250-300k
Id say an additional 20-25% resource expansion is a good investment
