<br /> <br />Elsewhere, oreshoots also appear to be controlled by the lntersec.tians of veins, <br />parttalariy the intersection of northeasterly striking veins with the veins of the <br />Graben wail. Stage 4 gold ores. so iryortant in the northeasterly veins, have gained <br />access to the Graben wail veins at these punctures (Langston, 1978), foradng steeply <br />raking oreshoots (figure 6). <br />Post Orc Faulting: <br />tuning at Sunnyslde 1s plagued by widespread post ore faulting, displacing both <br />veins and oreshoots. Yost of this faulting has been found to be of ~~ reverse nature <br />(Still, 1984; Read, 1987), the larger structures generally striking nearly north- <br />south and dipping to the east. The result is a general dawn dropping of the veins to <br />the west (figure 2). This fact, coupled with the southwesterly rake of the <br />oreshoots. has allowed mining to occur at progressively greater depths moving <br />westward (figure 6). <br />^EST E~3T <br />VEIN E • F <br />4ttERSECTloNS <br />r--~-~ <br />~rw tMt. <br />LnTLE W1RY <br />INTERSECTION <br />7o tMt ~xiae• <br />/~~1 <br />[~P LLrd <br />i/t tIYK <br />4 tilt ~` <br />. t[l,t 1 <br />c tiva ` ,e.eoo~ <br />SiOPES ~, <br />[ t[vn <br />~~i <br />tLlt <br />~T~~ cAO6s-sECnoN <br />t, suNrnslDE vEiri <br />J, ~ <br />'Et 0 [cu[ u tar bbd <br />G <br />FIGURE 6 <br />70 <br />71 <br />
