im a bit concerned, page-33

Could someone tell me what the open pit dimensions of stage 1 are , width, length and depth , i read that average head grade for the first 3 years is expected to be 3.16% Cu , how much of the open pit is expected to be mined in the first 3 years. The reason i ask this is that i dont see these type of grades within the first 80m depth on page 5 of one of their presentations (link below) . Cashflow from stage 1 is expected to repay debts and fund stage 2. What is stage 2 funding requirements and when is stage 2 expected. Any replies would be appreciated.
