This report sets forth the geology and economic possibilities of the Brandy Brook and Silver Pond belts of magnetic anomalies, Cranberry Lake quadrangle, St. Lawrence County, northwestern New York.  each belt contains a known magnetite deposit, partly explored through diamond drilling by the U.S. Bureau of Mines.  The Brandy Brook Northwest deposit is a body of low-grade to medium-grade ore, possibly of lathlike shape.  The Silver Pond deposit has no commercial interest at the moment.  One of more promising magnetic anomalies remain to be tested by drilling.
