persistence of the joints was also widely variable, but ranged from low to medium. <br />Apertures of the joints were tight to moderately open with slightly rough to rough <br />surfaces and were highly to completely weathered. The second primary joint set <br />exhibited a strike ranging from 40 degrees to 210 degrees with dips ranging from <br />80 degrees to 90 degrees. This joint set had similar properties to primary joint set <br />1— very poor to poor quality RQD, moderately spaced joints, low to medium <br />persistence, moderately open to tight joint apertures, and slightly rough to rough <br />rock surfaces, and high to complete weathering. Foliations exhibited a strike <br />ranging from 175 degrees to 180 degrees with dips ranging from 25 degrees to 35 <br />degrees. The spacing between of the foliation varied, but was typically close to <br />moderate. The persistence of the foliation was also widely variable, but ranged <br />from low to medium. Apertures of the foliation were moderately open to tight with <br />slightly rough to rough surfaces and were highly to completely weathered. <br />Small blocks may form in this area due to the orientation of the highwall and joint sets of the <br />rock. In addition, due to the fractured nature of the rock and highwall weathering, raveling of <br />small to medium sized rocks can also be expected. These rocks resulting from block <br />formation and raveling are anticipated to be limited in size, and should be retained on the <br />bench below the highwall and only cause local operational delays. <br />Sta. 1+00 to 1 +70 consisted of primarily of granitic and biotitic gneiss with <br />localized pegmatite intrusions. Rocks observed within the highwall typically <br />exhibited low to high compressive strength (estimated) and very poor to poor <br />quality RQD. Two primary joint sets were evident. The first set exhibited a strike <br />ranging from 330 degrees to 340 degrees with dips ranging from 60 to 70 degrees. <br />The spacing between of these joints varied, but was typically moderate. The <br />persistence of the joints was also widely variable, but ranged from low to medium. <br />Apertures of the joints were tight to moderately open with slightly rough to rough <br />surfaces and were highly to moderately weathered.
