Location and accuracy This prospect is said to consist of claims that were staked as early as 1907 on the north side of Berg Basin somewhere between the mouths of Berg Creek and Aaron Creeks. The location is poorly known and the propect may easily be a mile or more from the coordinates in section 23, T. 65 S., R. 86 E., of the Copper River Meridian. However, there is little information about the Berg prospect. Early reports describing it (Chapin, 1916, p. 78; 1918, p. 75) include references to the Copper King prospect (BC002). Parts of some of the early descriptions of the Berg prospect are ambiguous and may actually refer to a deposit in Berg Basin to the west in the adjoining Petersburg quadrangle.

Geologic setting

Geologic description

The country rocks in the general area of the Berg prospect (Koch, 1996, 1997) are Mesozoic or Paleozoic pelitic schist and paragneiss, and subordinate amphibolite and marble. Ambiguous early descriptions suggest that the prospect is an auriferous lode deposit. No other geological information about this property has been made public. Still and others (2002) investigated the area and did some sampling but found no evidence of mineralization.
