Welcome Creek is on lower Rock Creek north of Philipsburg and immediately west of the one time community of Quigley. Gold placers were discovered on Welcome Creek in 1891 and it has been estimated that the stream produced at least $30,000 in gold prior to 1904. The district then lay quiet until the boost in gold prices during the Great Depression. From 1931 to 1941 excluding 1940, the sluices of the district produced small amounts of gold. In 1932 one operator produced $130 in gold. The largest production for the district occurred in 1941 when eight ounces of gold were recovered. This gold tested at 920 fine and was apparently from two different sources. Some of the gold was described as light yellow while gold from another source was a dull yellow. The gold was found in association with magnetite hematite and simonite (Lyden 1948; Rowe 1911; Sahinen 1935).
Welcome Creek flows through an area of Beltian rocks which have been intruded near the mouth of the creek by a granitic stock. The gold apparently originated in small veins related to the Tertiary intrusives and eroded out of the veins by the flow of the creek to bedeposited in stream and bar gravels. No production has been reported from deep mines (Sahinen 1935; Lyden 1948).
BOUNDARIES OF THE DISTRICT
Sahinen (1935) and Lyden (1948) state that Welcome Creek flows east out of the Sapphire Range and empties into Rock Creek about 14 miles south of Clinton and about 10 miles south of the Bonita siding. Figure 1 shows the district as defined by the AMRB (1994) which includes the Welcome Creek drainage and some additional area to the north and south.
HISTORIES OF SELECTED MINES
Big 8 Placer
The Big 8 placer in Welcome Creek is the only mine with recorded production. The operation was listed as active in 1934 (WPA 1941; Gilbert 1935).
