The Sun property is located on Mount Kemball, one kilometre south of the Revenue mine (082FNW106), 25 kilometres east-northeast of Slocan City. It was part of the Silver Cup property (082FNW114). The property is located within Kokanee Glacier Provincial Park.

The Sun claim was Crown granted in 1911 and the same year two cars of a good grade silver lead ore were sacked and ready for shipment. The focus of exploration appears to be veining associated with metamorphic rocks, intruded by the Nelson batholith. In 1917, D.H. Nellis shipped 31 tonnes of ore, yielding 84,600 grams of silver and 12,338 kilograms of lead.

This property lies at the head of 'Woodbury Creek on the ridge between it and Sawtooth Creek, a tributary of Keen Creek, at the 2408 metre elevation. It may be reached by approximately 8 kilometres of trail from where the Scranton road turns up Pontiac Greek.

The E.L., Silver Cup (Lot 6507), Moonlite, Evening Star, and Sun (Lot 6955) claims extend in a northeasterly direction along the strike of the vein outcrop. These claims lie near the western edge of a more or less rectangular block of 33 claims and fractional claims that is roughly 5 claims wide and 6 claims in length. All these claims were Crown-granted to D.H. Nellis, some in 1907, and the remainder in 1911.

Very little information is available on this property and it is not known when the claims were located. A 1911 report states that 3 men worked on the Sun claim from June to December and 2 cars of ore were sacked ready for shipment. In 1917 Mr. Nellis shipped 35 tons of ore, reported to be from the Sun claim. The main workings are on the Silver Cup claim (082FNW114). Here Mr. Nellis drove a crosscut in a westerly direction, about 30 metres below the outcrop, on the Woodbury side of the divide. The crosscut is 22 metres long and intersects the vein 10 metres from the portal. A winze has been sunk on the vein, and 5 metres below the adit level a sublevel has been driven on the vein to the north of the shaft for 11 metres. About 5 metres back from the face the stringer of galena has been underhand mined for a few metres. The winze is reported to be 14 metres deep with a 15-metre drift to the south off the bottom. This lower level was inaccessible when the workings were examined in 1949.

In 1940 J. Flagel of Ymir shipped 3 1/2 tons of ore from the Silver Cup. Three claims, the E.L, Silver Cup, and Moonlite, owned; by Mrs. C.A. Nellis, were optioned to A.C. Neiman & associates late in 1949. The only work reported at this time was done on an access road to the property.
