Darlot

Darlot Gold Mine is 120 kilometres north of Leonora and 58 kilometres east of Leinster in central Western Australia. The mine is located in the Yandal Greenstone Belt. Ore at Darlot is mined as an Underground Operation and treated through a 0.8Mtpa plant producing around 80,000 oz a year.

Darlot is exclusively a fly-in fly-out site and is a 90 minute flight from Perth.

Mining Operations

Mining at Darlot is conducted by underground methods with ore transported to the treatment plant by haul trucks operating through two declines. Access to the 800m deep underground mine is via two portals in the historically worked open pit.

Conventional longhole open stoping is conducted in the massive central areas of the Centenary ore body. Narrow longhole stoping methods are applied to the Walters and Thomson lodes and room and pillar type methods are applied to the flat loads of Darlot. Paste filling is available and used where required.

The majority of underground mining activities are conducted by Goldfields' employees, with contractors employed only to undertake specialized tasks. Current production rates have the mine producing around 50kt of ore per month and advancing development of around 230m per month.

Processing

The Darlot processing plant has a capacity of eight hundred and fifty thousand tonnes per annum. The three stage crushing circuit has the capacity of one million tonnes per annum and the grinding circuit consists of primary and secondary ball mills which feeds a gravity circuit and conventional Carbon-in-Leach (CIL) circuit. The gravity circuit includes a Knelson concentrator which recovers approximately 20% of total gold production. The CIL circuit includes leach and absorption tanks followed by a 4 tonne capacity pressure Zadra elution circuit. The plant also contains a hydrogen peroxide cyanide destruct circuit discharging to two tailings storage facilities.

Currently, the overall metallurgical recovery averages around 95%.

Exploration and regional development

Located in the eastern Goldfields Province, the Darlot area has a long history of gold exploration dating back to the late 1800s. The Darlot Mine has been operating for over 20 years both as open cut and an underground operation and is one of the largest known mineralized systems in the Yandal Greenstone Belt.  The mine has an extensive tenement holding in the district and Gold Fields’ exploration strategy at Darlot is focused on increasing the ore reserve as well as finding new ore bodies.

Sustainable Development

We are committed to building a safe, sustainable and profitable business. We understand that environment, community, health and safety are integral to a genuinely sustainable future. Every employee is expected to embrace these values in order to achieve our communal goals. 

At Darlot our approach to mining safely embraces leaders exhibiting a genuine promise to improve safety, coupled with a workforce that recognizes and manages workplace risk. 

Protection, promotion and enhancement of the health and wellbeing of our workers is as vital as protecting their safety. This is achieved through providing emergency medical support, enhancing employee wellbeing through education and proactive involvement and  identifying and managing health risks.

Environment

Our commitment to the environment can be seen in every facet of our business. We understand our legal requirements and how to manage our environmental impact in order to meet compliance requirements. We also conduct a number of awareness programs and our success in this field can be seen in our ISO14001 certification for environmental management and our meeting of the International Cyanide Management Code.

Community

Our dedication to the environment is matched with an equally strong dedication to the community. We maintain positive relationships with local Aboriginal groups, pastoral stations and our stakeholders.
