I haven't matched up your figures, but as the poster above responded, keep in mind previous financial years had significantly higher earnings and work. The business as you can see in subsequent earnings reports have been dramatically reducing as the operations 'change'. The forgiving factor is they've paid down debt and while revnues and business have shrunk, the case for upside is that the share price relative to what cash their generating is positively undervalued.

The unknown is I think the half yearly to come out soon will demonstrate how much further revenue, profit and cash generation has fallen. Obviously we all expect it to, in absence of new mining work , but the telling tale will be what the overall level is at now that debt is repaid. If the rate of decline has slowed, we can extrapolate that the prev cash balance + future cash generation still points to the share price being quite lot, without factoring in upside for new work when the industry or business hopefully (eventually) turns around.

If say the last report's numbers continues then they are printing cash relative to their market cap and previous cash backing.
