The Bjorkdal Mine was acquired by Gold-Ore Resources in January 2008. At that time, the historic gold producer was processing gold bearing ore from underground and from open pit operations at an annualized rate of 20,000ozs/annum. By December of 2008, thanks to good planning and ingenious thinking, the mine was producing gold at an annualized rate of nearly 40,000ozs/annum.

In February 2009, Gold-Ore announced an underground mine expansion plan intended to raise gold output levels by 20% by providing access to two new levels of underground ore. This expansion has allowed the mine to produce mill feed at a rate of 1400T/day. Additionally, in March 2009 Bjorkdal installed a second Knelson Concentrator to further enhance gold recovery. The Knelson unit, a fully automated KC-XD30; was installed in conjunction with the existing gravity circuit consisting of Richert cones, spirals and shaking tables and a Knelson KC-CD12 treating spiral concentrates. There is a downstream flotation circuit and site personnel understand the economic benefit of optimizing recovery of free-gold prior to flotation.

In September of 2009 Mike McLeavy; KGS Manager of Process Technology visited the Bjorkdal site to assist with process optimization of the Knelson unit. "The installation quality here is excellent. The XD30 has been recessed into a platform so there is access to the top of the machine at waist height. All pipes are well supported with good slopes. There is a slurry splitter installed on the concentrate line that takes a sample of each concentrate flush. There is access to get good feed and tailings samples." stated McLeavy upon return to Knelson corporate headquarters. "When I arrived, the unit had been fully commissioned and operating for almost 3 months and the results that were being achieved were very good." noted McLeavy.

"We are very satisfied with the reliable operation of the KC-XD30, as well as for the KC-CD12 that we have had in production for 3 years now." stated Thomas Trautmann; Bjorkdal Plant Metallurgist.
