The CEO of SDAS (subsidiary through which CEZ owns Geomet) was not very excited about tin, let alone tungsten/wolfram.

This is what he said in a 2020 interview:
And what about the accompanying extraction of other raw materials from the rock, such as tungsten, tin, tantalum?
They are found in the deposit in low concentrations, in low metallicity, so the effect from them will not be nearly as significant as from by-products for cement manufacturers. In this important detail, we differ from the original vision of EMH and Geomet.

And this is what he said in a 2022 interview:
Mining in the Ore Mountains will also bring other metals, such as tungsten, tin, copper, rubidium, cesium... Do you already know how many tons or kilograms of these elements will be obtained during mining at Cínovec? And can you extract them?
Only some of the ones you mentioned can be obtained from the ore. The extraction and level of trading of all these potential raw materials will be decided primarily by economics. The priority of the planned mining is the extraction of lithium, tin and tungsten. In the case of tin and tungsten, this is the first tens of thousands of tons of these metals during the existence of the mine. Work is also being done on effectively combining relatively different technologies for extracting tin and tungsten in addition to lithium. Rubidium and cesium give the impression that they are elements of the future, but they are metals that are almost never traded in their pure form on a global scale. Among other things, because their production in pure metallic form is extremely financially and technologically demanding. For example, their salts are a useful raw material for glassmaking, rubidium can serve as a substitute for lead in heavy glasses. Among the alkali metals, however, next to lithium, the greatest interest will probably be in potassium. In the form of salts, it is an important raw material for the production of fertilizers.

So in 2020 he was very skeptical, in 2022 he admitted tin and tungsten are good as by-products. Maybe in 2025 the process was reworked so that it helps opex in a bigger way. Low concentration big magnetic ore and a big resource. Not great but there are way worse mines in the world.
