1905:

Frank Yasuda, Nevelo Yasuda, Charles McNett, James Minano, and Thomas Carter stake Discovery Claim on Little Squaw Creek, Chandalar district, Alaska.

1906:

Gold placers discovered on Big Creek and St. Mary's Creek, Chandalar district. Approximately 100 miners are working in Chandalar area.

1909:

Four gold veins are discovered, reportedly the sources of the placer gold. A small stamp mill is shipped into the area to test ore from the Little Squaw Lode and other lode claims.

1909-1941:

William Sulzer, former governor of New York, acquired the majority of the most promising prospects in the area. He financed exploration and development through his company, Chandalar Mines Company and later, as the major shareholder of Chandalar Gold Mines, Inc. when the two Chandalar companies merged in 1926.

1916:

Most of the shallow placers are playing out so miners shift their interest to the placer drift mines (underground operations). The most notable of these is the Little Squaw Bench, including the Mellow Bench. Approximately 29,000 ounces of gold were recovered averaging 1.0 oz/cubic yard of gold in the gravels with spikes of up to 4.6 oz/cubic yard. Some individual nuggets were over 10 ounces.

1920s:

Drift mining continues in the Chandalar district.

1937-1939:

William Sulzer acquired federal mineral patents for the principal discovery claims and a series of reports were produced to prepare the properties for production. However, no mining and few exploration activities occurred.

1930s:

Chandalar district mining diminishes as the remaining pay zones are either deep or lower grade, or in many cases, no longer frozen (necessary for drift mining).
