AR Help

Here are pictures of the cement test and it is white on the bottom. Picture of a plain copper place and then copper plate used in cementing, I tried to get the white on the copper. Finally a picture of the ore that I am using.
All tests are to be done in there own containers individually and using 5 grams weighed reactant and an eye dropper or two of aqua regia used.

I have tried sodium chlorate and got a fairly violent reaction with lots of popping. I did not notice anything drop. When the weather clears I will weigh 5 grams sodium chlorate and add slowly hot.
I did try a test of oxalic acid hot dissolved with no results.
I tried ammonium chloride dissolved with no results.

I will also try sodium chloride ( sea salt ) dissolved and look for a reaction.

Thank You for any comments and suggestions in advance.

Thank you for the comment about nice AR. For a first time cooking this correctly I hope it works nice.

Sodium chloride test is positive when checked under a magnifying glass. The aqua regia is now green. Only two eyedropper full were used. I think I may be dealing with the near perfect mix of silver where you have to drop the silver first then go after everything else after another cook down. Picks to follow.
I will continue with the rest of the tests.
