|Location and accuracy||Magnet Creek is a north-flowing tributary to Gold Creek that was mined near its mouth. It is about 5 miles north of the north (6180) peak of Poss Mountain and flows through the west half of section 14, T. 31 N., R. 10 W.|
Geologic descriptionGold was discovered on Magnet Creek in 1900. Reed (1938) reported that the modern channel of Magnet Creek was mined from an open cut near its mouth. A high bench near the mouth of Magnet Creek on Gold Creek (CG080) was also mined for about 500 or 600 feet. Claims were staked and there was activity on the creek during several periods between 1973 and 1999. Kurtak and others (2002) sampled and panned at several locations along Magnet Creek. Several of their samples and panned concentrates contained visible gold but most of the gold they found seemed to come from open crevices in the bedrock below the overlying gravel rather than from the gravel itself.

|Mineral deposit model||Placer Au (Cox and Singer, 1986; model 39a).|
|Mineral deposit model number||39a|
|Age of mineralization||Quaternary.|
|Workings or exploration||The modern channel of Magnet Creek near its mouth and a bench there were mined sometime prior to 1938. There was activity on the creek during several periods in the 1970s and 1990s but there is no record of production. Sampled by Bureau of Land Management in their study of the mineral resources of the Koyukuk mining district (Kurtak and others, 2002).|
|Indication of production||Undetermined|
|Production notes||An uncertain amount of gold was produced before 1938 from near the mouth of the creek, and there was mining in the 1970s and 1990s.|
