Situated in the Eastern Goldfields region, our Agnew mine site is 23 kilometres west of Leinster, 375 kilometres north of Kalgoorlie and nearly 1,000 kilometres north-east of Perth. Acquired in 2001, Agnew Gold Mine produces over 250,000 ounces of gold per annum.

Gold is sourced from the two underground operations and processed via a CIP plant. The majority of our nearly 500-strong Agnew workforce lives permanently in Perth and commutes to site on a fly-in/fly-out roster from Leinster.

Our people fly to site on a chartered jet departing Perth Airport’s Terminal 2 on weekdays. Flight time to Leinster is approximately 60 minutes. The Leinster airport is approximately 15 kilometres from the town of Leinster, which in turn is approximately 23 kilometres from the site. Traveling to and from site is via a chartered coach service operating both mornings and evenings. Travel time is approximately 25 minutes.

Camp life
The town of Leinster is a closed town which means 100 percent of inhabitants are directly associated with either BHP Billiton or Gold Fields in some capacity. The town offers a suite of services to our fly-in fly-out workforce including free use of gym, swimming pool and recreation facilities, a supermarket, Tavern Bistro and an internet café.

Meals are provided at the company’s expense via the Leinster mess facility. Accommodation includes an ensuite single room with fridge and colour TV.

Mining operations
Mining operations at Agnew currently consist of the Waroonga Underground comprising of the Kim, Main and FBH lodes. The underground workings are accessible from the old Waroonga Pit, via the Kim decline which extends to more than 1,300 meters below the surface. Stopes are mined by mechanised sub-level stoping and backfilled using paste fill, with underground production and development carried out by contract miner Barminco Limited.

Access to the Lawlers underground is via the New Holland and Genesis Pits and mining is predominantly via long-hole stoping of the Sheeba, Genesis and Cinderella lodes.

Processing
The Agnew process plant has a capacity of 1.3 million tonnes per annum. The crushing and grinding plant feeds a gravity circuit and a conventional Carbon-in-Pulp (CIP) circuit. The gravity circuit includes a Knelson concentrator and an in-line leach reactor which recovers approximately 55 percent of total gold production. The CIP circuit includes leach and absorption tanks followed by a pressure Zadra carbon elution circuit. Currently, the overall metallurgical recovery averages around 93.5 percent.

Exploration and regional development
The mine has a large tenement-holding of over 600 square kilometres in the district. Along with finding new ore bodies, Gold Fields’ exploration strategy at Agnew is focused on increasing the ore reserve to greater than 1.5 million ounces, which equates to more than seven years’ mining life.

Typical rosters
Most graduate and professional roles operate on an 8 days on, 6 days off roster. Other rosters in operation include 4 days on, 3 days off; or 8 days on, 6 days off,7 nights on, 7 days off, however these are typically reserved for management or production employees.
