Ann: Warrawoona Delivers Strong Production in January, page-18

Apologies if I am overposting here.

Ive tried to work backwards to ascertain end of Jan prodn and possible forecast out. Forgetting about changes to grade just working on throughput increases.

Based on a 4w month and 4% increase w3Jan, 8% increase w4Jan, I think the Jan weekly production looked something like:

w1 1265
w2 1265
w3 1315 (+4%)
w4 1366 (+8%)
tot 5211 (reconciles to 5210oz in ann)

So annualised prodn based on last wk of Jan = 1366x4 = 5464 p.mth = 65,568oz.pa

They plan to increase remainder of March qtr to 10% above nameplate however in early Feb they acheived 347 t/hr v 300 t/hr nameplate which is a 15.6% increase. If you forecast those out you get:

1265 x 1.1 = 1391wk x 4 = 5566p.mth = 66,768 p.a (+10%)
1265 x 1.156 = 1462wk x 4 = 5848p.mth = 70,179 p.a (+15.6%)
