Information on the method <br />and procedure utilized for second order accuracy is enclosed. We have <br />also enclosed a map of the mine development as of April 4, 1986. This <br />map shows :: conservative angle of draw to the surface. The angle of <br />draw shows that Subsidence Point 1 would be the only monument affected <br />prior to the next monitoring survey. <br />The subsidence monitoring for May 1986 was performed prior to receipt <br />of the Division's letter of May 16, 1986. In view of the Division's <br />decision in that letter, would a survey conducted in May be acceptable <br />versus the annual survey conducted in December? December is a difficult <br />tune of year for monitoring due to snow cover. <br />Sincerely <br />Stephen Self <br />General Manager <br />SS/11 <br />Enclosures <br /> <br />
