Ram01 unfortunately, the number of veins or even their folding is not a 100% indication of their level of mineralization. On gold deposits, the veins usually were formed as quartz percolate in the host rock and later very hot and acidic fluid containing gold flows and deposit in low-pressure regions, this low-pressure region depends on folding or other anomalies caused by the earth crust movements, also as the fluid rises up in the crust it loses it acidity as it reacts with the host rock and also loses temperature causing the gold to deposit along the way up . So we cannot really say that because there is a folding as a consequence there will be high grade, it is possible but not definitive, also that's the reason why there are multiple veins but just one that is mineralised.
