RE:RE:Hope we find the same grades!Taken from New Found Gold Technical Report. Couldn't copy the picture. Also, a video by Quentin Hennigh is also interesting, about the structural zone.
Figure 8.4. Left, drill core from the Keats zone (NFGC-19-01), Queensway gold project; right, core from the Eagle zone, Fosterville mine. Comparison of intense quartz stock work with relict black shale fragments from each deposit. Specks of visible gold are present in quartz veins and their selvages. Gray patches contain fine grained antimony sulfides, boulangerite on left and stibnite on right. Source: NFGC
