February 2022 by Chris Ralph
Q: Aside from the softness scratch test and other methods of identification, what feedback would you have on identifying gold in hard rock that may be mixed with other metals that affect its color?
Q: I believe I have found a deposit that contains iridium. What can you tell me about iridium? Are there any tests I can do in the field to confirm it is iridium? How much is iridium worth? Where can I get it assayed? Can I refine it myself?
