QUARTZ VEINING ALONG SHEAR ZONES (3 replies)

Hello everyone

I have some few questions to ask: 

I encounter an outcrop of quartz vein larger more than 5 feet wide,first assay of a sample shows about 0.4ppm,i decided to do trenching and pit sampling...few samples by sorting show few gold by panning..there is any possibility that vein will have enough gold as i go down...by taking coordinates and locate them on a map using gis software it shows that a place is near a shear zone and a contact between granitic and ultaramafic rocks,there is any possibilty that this vein is a reef along a shear or within a shear zone...what other cheap exploration strategy can i do rather than above.

thanks in advance

I would suggest getting a Shaw backpack drill and drill down about 50' to 60.' Drill a few holes and do some assays and panning. I do fire assaying for gold & silver, $40 per assay.

There are many places where isolated small quartz veins may give high grade gold mineralization which may support artisanal gold mining. But they may be far placed from each other that commercial mining would not be possible. Get a proper geological mapping of the area done. A geologist could be able to deduct the space -time relation between the granitic rocks and the ultramafics, timing of  shearing,  emplacement mechanism of quartz veins and look for alterations along the intrusive contact.   All these would help you to plan a  surface sampling program and interpret the results once available.  You may go for drilling only after you develop confidence in the surface data as it is going to cost you a lot of money and you are looking for inexpensive methods.
