RE:RE:RE:RE:RE:DDH-WF-029In the 43-101 interflow sediments are described as pale cherty to dark carbonaceous varieties. Still looking for a description of the seds that mark the boundary between the upper and lower lunnon basalts.
amazing enough no mention of the type of setting that they recently discovered : ie: pyritic seds and rich vg. The shears have legs though. Incredible discovery. Note: all known gold ......
have a read from the 43-101
All known gold mineralization is confined to the Lunnon Basalt below the ultramafic contact, with the vein systems terminating abruptly at this contact. Gold mineralization occurs in three broad, steeply dipping, north-northwest striking quartz vein systems within a sheared biotite-rich, pyritic zone of the Lunnon Basalt (Figure 7.5). A Zone and the Western Flanks both occur to the north of a major north-northeast trending structure (Alpha Island Fault) and the Beta mineralization is located to the south of the fault. The A Zone and Western Flanks shears are interpreted to be the channelways for rising ore fluids, with the basalt/ultramafic contact acting as a fluid trap. The subsequent increase in pore fluid pressure induced preferential hydraulic fracturing of the brittle mafic and felsic rocks to form the quartz veining, with the migrating ore fluids causing the wall- rock alteration.
