Jun 28, 2011 (A Wilson) - The property consists of a pegmatite dike exposed in three workings. Contacts with the host rock are not exposed in the vicinity of the workings. The pegmatite dike trends 060° and is probably vertical to steeply dipping. The pegmatite dike is exposed for 300m and may extend to 900m.

Jun 28, 2011 (A Wilson) - At the main working quartz and pink microcline are intimately mixed. The microcline feldspar occurs in 6 to 8 inch crystals in a close intergrowth of medium-grained quartz and feldspar. The largest mass of high-grade feldspar measured 8 by 10 inches. A small stockpile of small pieces was on the site in 1944. Crushed smoky quartz and microcline masses as much as 6 feet in width were found at a shallow pit. Hewitt noted that the largest pure crystal of potash feldspar ad the main workings measured 2 feet in length.
