Well, I noticed it. AND:
maxamgold.com
Cooley, Maxam Consulting Chemist, provided a presentation on the difficulties encountered when assaying different types of ores. Most assay laboratories will neither take the time nor spend the finances to perform a difficult assay. Commercial laboratories have forgotten that every assay charge (crucible charge) should be calculated based upon the composition of the ore (this is a college course and numerous books have been written on this subject). In spite of this fact, these laboratories charge $15 per sample using a "standard" flux (for the crucible charge). This "standard flux" is calculated for a quartz vein which is totally incorrect for complex ores such as sulfides, black sands, carbonaceous ores, etc. Cooley insists on a minimum of three assays using different procedures such as Aqua-Regia Digestion with AA analysis (Finish); A Chiddy Extraction (Reduction) using a chlorine system; Fire Assay with both Gravimetric and Instrument Finish. The samples must all corroborate with one another or they are ignored. Maxam continues to follow this very conservative approach in reporting all results.

So, I asked him a question on sending material to MCM for testing and was surprised at the answer. Then I tought about the 5 gallon pails I had sent Bob Barefoot at DCRS to use ION BOMBARDMENT in the DCRS-Mongoose Type Machine a few years ago and it all make sense. In one bucket I got back 3 grams of gold that back calculcated to 1.77 OPT AU based on a 5 gallon bucket weighting a standard given amount. Was it 50 pounds...100 pounds?
Maxam Custom Milling needs 5-5 gallon containers of material to have this testing done. Not a few Ounces!

P.S.- P-7 still has a Mongoose-DCRS unit installed.
P.P.S.- DEFINE : "carbonaceous ores" maybe as a carbonite - an igneous rock containing less than 50% carbonate materials. Occures as lava flows, dykes and sills and commonly associated with alkaline igneous rocks with in rift systems. Formed by the derivation of carbon rich fluids from ascending magmas originating from partial melting of Mantle Peridoite. ( P Kearney- Dictionary of Geology- New Penguin.
Then, Jesse wrote me yesterday at MMU thread ( Marum resouces ) :
<<..RE:
Chuca, ppm = gram per tonne.
----
Remember that volcaniclastics means potential diamond host too, of course. It is the mantle-sourced volcanoes that bring diamonds to the surface (already proof that these are mafic/ ultramafic, meaning, mantle originating). Marum's already found many various DIM's.

P.P.P.S.- what is a DIM? Diamonds In Mineralization?
P.P.P.P.S.- Granitic Host Mountains are all in the TECHNICAL and USGDS sections of maxamgolg.com NEW NEWS SECTION of the lasy 6 weeks..read and understand...buying OPPORTUNITY at MXAM:BB in my humble minerialized opinion. But, hey, I am a dinosour! decimal Dino= Chuca rememvber PPM = Grams Per Ton!!! ( I keep getting decimalized with all my investments, dam.
