Placer mining was reported in the Cache Creek drainage of the Dutch Hills by 1906.

The mining camp of Petersville, Alaska served as the area Post Office for several years in the late 1920s and early 1930s.

A cluster of deposits is in the main part of the Yentna district, near the Dutch Hills.

[1][2][3][4][5][6][7][8] A bucketline dredge was constructed in Cache Creek in the 1920s, and used locally-abundant coal to fire the boilers.

The placer mine continues operating today, and the company is actively exploring lode deposits.
