The focus will now shift to adjusting and optimizing both secondary crush - ers’ by-pass chutes and shuttle con - veyors, which is necessary to increase availability and daily throughput lev - els to plant design. This work is ex - pected to be completed in May 2013. The mill facility produced 16,841 ounces of gold in its start-up quar - ter . As per the mine plan, the average head grade was 0.64 g/t and mill re - coveries averaged 80%. Mill recover - ies reac hed 86% in March, which is in line with the model recovery . The gravi - ty circu it is expected to be commissioned in the third quarter coinciding with dai - ly throughput closer to design capacity . In the frst quar - ter , 10.43 million tonnes were mined, of which 8.51 mil - lion tonnes were waste (including 4.4 million tonnes of overburden). The run of mine (ROM) ore stockpiles con - tain over 2.3 million tonnes grading 0.70 g/t. The low- grade stockpile was also increased by 0.62 million tonnes to 1.58 million tonnes grading 0.40 g/t. The frst quarter mining rates in the open pit averaged approximately 123,000 tpd (149,000 tpd in March) of total material moved (overburden, ore, waste and re-handling). Ore min - ing occurred in narrow , lower grade zones just north of the main Calcite zone where higher localized dilution reduced the average plant feed grade (i.e. mining widths of minimum 15 metres). In April, the ore mining has transi - tioned into the wider Calcite zone (+80 metres) where higher grade ore is to be mined during the second quar - ter and where dilution is expected to be reduced. The reconciliation work indicates that the mining grades correspond well with the reserve block model, vali - dating the value of the grade control methodology (RC drilling) and appli - cable mining dilution. The company has a mining feet of 20 haul trucks and four shovels avail - able for use, which more than meets the requiremen ts of the 2013 mining operation. The company had given a produc - tion guidance of between 350,000 to 400,000 ounces of gold for 2013 and total cash costs of between $800/oz and $900/oz to be reported after com - mercial production is declared. The company now believes that producing 350,000 ounces of gold will be at the higher end for 2013 production and will update its guidance in the second quarter . As of March 31, 2013, the company had approximately $170 million in cash and short-term investments, which includes a $70 millio n draw - down from its $90 million revolving credit facility .
