Hello Christopher,

The pricing of your raw material is not an easy process.

You have a polymetallic material, including rare earths and other strategic metals.

Here are some indications and questions that may help you on how to proceed.

First of all you have to define what can be economically extracted from the elements that are included in your sand. Then you can determine the percentages and estimate the prices.

Do you have any metallurgical tests to prove the separation of the individual elements (especially the REE)?

Do you also have marketability studies to evaluate which of your elements can be sold?

Finally, do you know if the final product will be separated purified oxides of the elements or a mixed concentrate? Because in the latter you will have to apply a discount percentage to compensate for the unseparated nature of the product.

A Net Smelter Return (NSR) model could help you at a first stage ( look for it in literature) but since you have rare earths included then it gets more complicated.

Based on my remarks can you give me more information about what you need to estimate? Then I can come back with more info and some references.

Prepare a composite sample of the heavy mineral sand, representing overall average composition of a survey part of the sand deposit. Determine both total heavy mineral wt. % and individual heavy mineral wt. %, by sequential processing of the sample comprising dil.. HCl treatment, drying, wt. loss, magnetite separation, weighing, magnetic and heavy liquid like bro mo form separation of different si eve fractions.

Estimate wt. % of different h.m. in each fraction and sum up respective wts. to

get wt. of each important h.m. and total h.m. Get the price of each important h.m. from the current market prices and calculate rough value of the ton n age of each important h.m. and for the total deposit at about 80% recovery.

It depends on the uranium thorium and rare earths content in the 98-99% monazite mineral grade.
