Geophysical Methods for Vein Imaging (2 replies and 2 comments)
Please join and login to participate and leave a comment.
Hello Everyone, we have recently acquired a claim with an old mine on it. We took some grab samples from inside the mine. We took samples from both the vein, and altered wall rock. We have done roughly 5 sets of testing with an average grade of ~15g/t AU. We have also had mineralogical analyses done and the mineralogy is consistent with a "orogenic lode gold" deposit. The vein and surrounding sulphidization has followed what appears to be a second order fault. In the vein the main sulphide is Arsenopyrite (~35%). The surrounding wall rock is altered to :illite and orthoclase (~70%) with Pyrite and Pyrrohtite veins (~2%). Their is minor chloritization in adjacent wallrock. What would be the best geophysical method to image the vein or stock work, aerial or otherwise.
Thanks for your help in advance!
