The proposed processing facility has been designed as a nominal 3,700 dmtpd concentrator plant (i.e. slightly in excess of the nominal mine production), although the initial absence of standby equipment requires that the design availability of the process plant be practically limited to 85% for early mine life and thus no more 3,300 - 3,400 dmtpd effective capacity is initially expected.
