The Good Hope mine at Hedley , British Columbia , was discovered four years ago . Since then , a few thousand tons of gold ore have been mined . The purpose of this paper is to present the evidence that has been assembled indicating the controls that resulted in the formation of the known orebodies . The ore occurs as irregular bodies of skarn within the limestone members of an assemblage of volcanic rocks and limestone lenses . The writer concludes that the skarn bodies were produced by alteration of limestone , that the gold was introduced during this alteration , and that a set of vertical fractures in underlying rocks were probably the channels by which replacing solutions entered the limestone . A nearby dioritic stock may have been the source of the solutions . The report was planned as a preliminary study , to be revised and expanded following further work at the property.
