In the last of these, ore sampling
, sample preparation, testing machines and routines are covered as practical guides to mine laboratory staff.
On the Alaska side of the border, in addition to efforts at A-J and Kensington, ore sampling
was continuing this summer at the Jualin Mine, located just to the south of the Kensington.
Work will commence on the upgrade to the intersection of the mine access road with the Great Northern Highway from early November, and CSI Pty Ltd is gearing up for the required modifications to the existing crushing and screening plant to facilitate iron ore sampling
and final product stacking.
Under current plans, based on continued ore sampling
this summer, the mine now sports more than 100 million tons of proven and probable reserves, at last enough gold to keep the mine open for 15 years.
Surface drilling operations were carried out in 1981 and 1983, and in 1987 the company began driving an adit (one-way tunnel) from the southwest ridge of Windy Craggy Mountain to allow bulk ore sampling
and to confirm the depth of the mineral find.
