Assay question

[Starlight]

Hi newbie here, first post, apologies for jumping straight in.

I'm trying to find out if the attached assay is good or bad and is worth following up and if so in any particular way.

I know little about the subject only what I've picked up on mining stock Canadian and Australian forums.

The samples were from holes dug a metre and a half down in virgin jungle in the Philippines. The island is known for being resource rich elsewhere.

That's it really,

Thanks in advance.

Welcome to us.
Some of the mining guys will catch this I hope.

It will depend on wether it is a lode mine, or placer. The sample with .23 Au will equate to 23 grams per 100 metric tons of material run. So if placer material, a very viable operation with big equipment. If you have to dig by drilling and blasting, milling, etc., you will most likely go bankrupt quickly.

I know it must be something in terms of units of measure I'm not getting here. I am not confident I know what unit of measure DMT is. If it is metric ton then I agree with @goldshark but what does DMT mean literally. My math converter app does not list any volume as DMT so I am clueless.

DMT stands for dry metric tonne

That makes sense, I always assumed a soil sample would be dried in the lab before assay and using that label verifies it. Thank you.

Dry metric tonnes is the metric version of the US's use of dry tons. Dry tons is a unit for measuring siliceous ores, used in measuring hard rock mine production. Cubic yards is the unit of measure for placer material. Placer material could be wet or dry, affecting the weight considerably. Since PM's in hard rock are measured in ozs. per ton, with water affecting a ton of rock considerably, the standard is the DMT, which could be tonnes or tons. Just have to recognize the abbreviations and country of weight measurement. The fire assay is still the same for lode or placer, taken by the use of 1 assay ton (tonne ). A fire assay will generally be higher for placer ground, then one would expect to recover with a gravity system. This is because a fire assay will get a very high percentage of metals still locked up in the other gangue material, which would normally be washed away in the gravity system of recovery.

I'm glad you said that- I was wondering if we'd dropped into the realms of psychedelics. (N-Dimethyltryptamine)

I first googled DMT assay and all sorts of protocols came up for drug related analytics. That’s why I asked. Comforting to know that we are not in the psychedelics crowd!

At times, it sounds like a few are.

True, but those of us who are not, quickly identify those that are.

By googling DMT assays, you are now on the DEA's watch list.

Guess I'll have to bookmark this thread in case I need an alibi.
