Perseus Mining, which operates the Edikan gold mine in Ghana and is listed on the ASX and TSX, reports that it “steadily advanced” the development of its second gold mine, Sissingué, during the June quarter. The open-pit mine, expected to produce 80 000 oz/a in its first 3,25 years and 70 000 oz/a over its five-year life, is located in Côte d’Ivoire.

According to the company, by the end of the quarter development works were tracking on schedule with approximately 61 % of the works completed. The development is progressing in line with budget, with incurred expenditure to date (including US$10,4 million of early works and holding costs) totalling US$67,6 million, and the forecast expenditure to complete estimated at US$47,8 million.

Off-site, detailed engineering is complete, as is the procurement of all significant long lead items of plant and equipment.

On site, the construction team continues to make sound progress, says Perseus, with the bulk concrete works associated with the plant and installation of underground services nearing completion. The majority of buildings including offices and the warehouse are either complete or close to completion, as is the erection of steelworks associated with the crusher and SAG mill.

The CIL tanks are being erected and the contractor responsible for the installation of the SAG mill has mobilised to site and will start work early in the September 2017 quarter. During the quarter the airstrip, tailings dam, mine camp and work on the river intake structure were also completed.
Assembly of the generators and power station control panels is well advanced and this equipment is on schedule to be delivered to site during the December 2017 quarter.

Given the progress made to date on all fronts, Sissingué remains on track to produce its first gold in the March 2018 quarter.

Perseus’s Technical Services and Human Resources teams have prepared comprehensive Operations Readiness Plans for the Sissingué operation with the objective of ensuring that following commissioning of the mine and plant, the ramp up to full scale gold production occurs as efficiently as possible.

A number of key contracts were awarded during the quarter to suppliers of critical goods and services for the Sissingué operation, including the mining contract which was awarded to Société de Forage et de Travaux Public – Mining SA (SFTP). SFTP is an experienced Malian mining contractor that currently provides contract mining services to Newcrest’s Bonikro gold mine and Randgold’s Tongon gold mine, both located in Côte d’Ivoire.

SFTP was also contracted by Perseus to carry out the bulk earthworks associated with the construction of Sissingué’s tailings storage facility, completing this task on time and on budget.

Grade control drilling, to be performed by SFTP as part of the mining contract, is expected to start in the September 2017 quarter to ensure that approximately three months of grade control data is available for Perseus’s mine planning purposes before SFTP commences full scale mining activities on site in the December 2017 quarter.
