The CGS spent three months in the 472 acre project area mapping, sampling, and studying the regional geology with emphasis on the extensive marble deposits of the Belden Formation and the potential for gold in gravels of Conundrum Creek. The resources of value are the gray marble deposit, as situated on the east side of Conundrum Creek in the vicinity of the lower water fall, and the white marble in the south portion of the claim block. The CGS mapping and sampling program for base and precious metals found no indications of resources of economic value in the many prospect holes examined or in the placer gravels of Conundrum Creek.
