USGS' Mineral Commodity Summaries list prices for 1-gram...

USGS' Mineral Commodity Summaries list prices for 1-gram ampoules of 99.8% (metal basis) cesium and 99.98% (metal basis) cesium.

They also itemise those for 50 grams of 99.9% (metal basis) cesium acetate, cesium bromide, cesium carbonate, cesium chloride, and cesium iodide.

• 2019 prices increased up to 3% over 2018 prices.
• 2020 prices increased up to 4.4% over 2019 prices.
• 2021 prices increased up to 9.3% over 2020 prices.
• 2022 prices increased up to 10% over 2021 prices.
• 2023 prices increased up to 20% over 2022 prices.

Lepidico's production volume will obviously provide for much larger contracts than the examples quoted above. Therefore, the prices we/Traxys achieve will surely not be proportional to the prices of these small quantities.

Additionally, the Summaries advise: "Because cesium metal is not traded in commercial quantities, a market price is unavailable." Nonetheless, the price increases year-on-year bode well for LPD, e.g., a 1-gram ampoule of 99.98% (metal basis) caesium selling for $78.70 in 2018 cost $117 in 2023, a 49% increase in 5 years.
