The Kensington and Jualin deposits are located in the Berners Bay mining district which lies on the northern end of the Juneau Gold Belt, a 120 mile long, 10 mile wide structural zone containing numerous mesothermal gold deposits. The district is flanked by Triassic aged mafic metavolcanic rocks to the east-northeast and Cretaceous aged pelitic sediments to the west-southwest. The contact between these two units has been intruded by the northwest-trending, Cretaceous aged Jualin Diorite stock measuring approximately five miles long by three miles wide. Regional deformation and shearing within and adjacent to the Jualin Diorite has resulted in emplacement of numerous goldbearing, mesothermal quartz-carbonate vein deposits.

The Kensington deposit is a mesothermal orogenic deposit of gold-bearing quartz veins.

The Project area retains additional exploration potential, as many of the areas along the three district-scale structural trends (Comet, Orval, and Lion’s Head shear zones) that host numerous gold occurrences have received only limited modern exploration attention.

The deposits with economic significance exhibit two distinct habits:

1. High-grade shear-hosted veins of limited strike and dip length within a narrow halo of locally auriferous quartz-veined diorite, and

2. Vein packages comprised of extensional vein arrays, sheeted extensional veins, and stacked en-echelon shear veins.

The mine property consists of two contiguous mineral claim groups controlled by Coeur Alaska: the Kensington Group and Jualin Group. The Kensington Group hosts the Raven, Kensington, Eureka, Johnson, and Elmira deposits. The Jualin Group hosts the Jualin and the Empire deposits.

The primary access to the Kensington and Raven underground mine areas is via the Kensington Portal at the 964-foot elevation. The Kensington Portal (previously known as the Jualin Portal) is in the same general area as the mill and ore stockpile. The Kensington Portal is the primary equipment and personnel travel way. The Comet Portal (792-foot elevation), on the eastern shore of Lynn Canal, serves as the secondary escapeway for the underground mine.

The primary mining method is transverse longhole stoping with paste backfill and mainly used in the center area at Kensington. Drilling shows that the Kensington orebody narrows to the north and south (4 to 20 feet thick), thus longitudinal longhole stoping is used. In Raven longitudinal longhole stoping is the predominate mining method as the orebody is mainly narrow, between 5 to 20 feet thick, with most of mining in material 5 feet or less in thickness.

A minor amount of drift and fill mining has been done in Kensington Block E (Zone 41). Where a drift is driven (15 × 15 feet) parallel to the ore boundary, and driven within the structure until the vein is too narrow to economically drive on, then the remaining ore is e ........
