The regional lake survey for central Baffin Island (parts of NTS 27B, 27C, 37A and 37D) was conducted during the summer of 1978.

This report presents analytical data for gold and 25 other elements obtained by re-analyzing lake sediments from 1 774 sites, collected at an average density of one sample per 13 km². Original analytical data selected from Open File 566, 567 and 568 (published 1979) for 11 elements plus loss-on-ignition in sediments, and uranium, fluoride, and pH values in concomitant waters are also included in this report.

The original reconnaissance surveys were undertaken by the Geological Survey of Canada under the terms of the Federal Uranium Reconnaissance Program. The Qikiqtaaluk Corporation, through the North Baffin Partnership Program, agreed to provide funds to reanalyze lake sediments collected in 1978.

E.H.W. Hornbrook directed the original survey program.

P.W.B. Friske managed the reanalysis program.
