Germany depended on the Spanish/Portuguese supplies entirely. I do not know the spanish numbers, but the first trade agreement between Portugal and Germany, in January 1942, established a supply quota of up to 250 tons/month, or 3000 tons/year, for which Portugal would receive 10 thousand tons of amonnium sulfate, 300 15ton rail wagons, 60 thousand tons of iron and steel plus assorted machinery, at pre-war prices. Another agreement would be signed in January 1943 for another 2800 tons, and another in April, (for 2100 tons) covering a period up to February 1944, again for large quantites of iron, steel, chemicals, machinery, trucks, etc, all at prewar prices. However, even with a massive increase in minin activity, supply at the end of the contract fell short by over 500 tons.
Consider what Germany was willing to give up to get the tungsteen. Consider also that the shortage of this metal was the main reason why the top-line german AT rounds, like the Panzergranate 40HK, that used a tungsteen core, were so rare. Consider that this shortage was the reason why tungsteen was of the list of usable materials in the development of german jet engines, despite it's high resistence to heat.
