Location and accuracy Kallands (also known as Hub Roadhouse) is a small settlement on the north bank of the Yukon River at the mouth of Illinois Creek The discovery of a placer tin deposit was first reported by Eakin (1913)near Calland [sic] (Wimmler, 1929). The location is assumed to be north of the Yukon River near the mouth of Illinois Creek, but it cannot be precisely located. This site is located at Kallands.

Geologic setting

Geologic description

The rocks in the vicinity of Kallands are a mix of Quaternary flood plain deposits, colluvium, alluvium, and terrace deposits (Patton and others, 1977). The rocks on the north side of the Yukon River in the vicinity of Illinois Creek are pelitic schist with interbedded marble and greenstone. The Lower Cretaceous Melozitna Pluton, a quartz-monzonite and granite stock, crops out approximately 13 miles to the north. The Kaltag fault, an east-northeast-striking, high-angle fault, crosses the Kallands area.
Wimmler (1929) reported that that a new discovery of placer tin near Kallands led to renewed interest in previously known occurrences of cassiterite on Illinois Creek (MZ017), Golden Creek (MZ018), and Moran Creek (MZ016). A hand drill was rushed into the area, and a little drilling was done on Illinois Creek, but its operation was soon suspended. At different times there were unverified reports that prospecting in this area produced a considerable quantity of of high-grade cassiterite concentrate, as well as some gold. Wimmler (1929) noted that the gravels could be processsed to produce a high-grade tin concentrate. The stream gradient of Illinois Creek is about 75 feet per mile.
