RE: File No. M77-378 , TR-14 , Commitment No. 4
Dear Mr . Sorenson:
On November 18 , 1993, the Colorado Mined Land Reclamation Board
approved Technical Revision No. 14 conditioned upon four
commitments by Sunnyside Gold Corporation. The following
conceptual plan is submitted to satisfy Commitment No. 4 in the
November 18 , 1993 approval letter . This commitment is as follows;
COMMITMENT NO. 4
THE OPERATOR WILL PROVIDE THE DIVISION WITH A PLAN TO CHARACTERIZE
CONJUNCTIVE FLOW WITHIN THE CEMENT CREEK DRAINAGE IN THE VICINITY
OF THE SUNNYSIDE MINE WITHIN 30 DAYS OF REVISION APPROVAL.
Sunnyside Gold Corporation engaged Golder Associates Inc. , a
consulting firm with offices in the Denver area, to prepare a
conceptual plan to satisfy commitment no. 4 . This plan or proposed
methodology to characterize the conjunctive flow in the Cement
Creek drainage is attached. The proposed methodology was adopted
based on information (ie. test holes, foundation drilling etc. )
that point toward the bedrock contact being too deep for simple
bedrock exposure, flow interception and measurement . If this is
not the case, it will be determined by the proposed geophysical
characterization and drilling and the plan could be modified.
The proposed site for measurement is in the immediate vicinity of
CC-1, a MLR permit area monitoring station. If a direct
relationship between surface flow and conjunctive flow is found to
exist, data is available dating from 1987 that would be useful.
