What Is Considered a "Good" TREO Grade in Ore?

	TREO Grade (% by weight)	Classification	Remarks
1	>10% TREO	High-grade	Very desirable. Usually indicates a rich deposit worth active development.
2	4–10% TREO	Medium-grade	Still economically viable, depending on the REE composition and location.
3	1–4% TREO	Low-grade	May still be developed if access and processing are favorable.
4	1% TREO	Very low-grade	Often uneconomical unless in bulk or with strategic value.

Tanbreez Resource Base: Approximately 45 million tonnes grading 0.40% total rare earth oxides (TREO)

GBB why are you less than half of even a very low grade ? You are off the chart for even very low grade. What would we call your classification? Maybe very very low grade or ultra low grade or so low grade it's not even worth mentioning low grade?

Mountain Pass Mine (USA): Typically grades around 6–8% TREO. At 100 metres

Bayan Obo (China): One of the largest REE mines, with 3–6% TREO but rich in Nd and Dy. Started at surface level

Tanbreez Resource Base: Approximately 45 million tonnes grading 0.40% total rare earth oxides (TREO) Located deep underground up to 340 metres
How will you ever be economical Especially given how difficult and untested the extraction of your hostrock is compared to these others which are far more easy?
