Tin is a Relatively Scarce Element According to the United States Geological Survey:
"Tin is a relatively scarce element with an abundance in the earth's crust of about 2 parts per million (ppm), compared with 94 ppm for zinc, 63 ppm for copper, and 12 ppm for lead."
There is a historic deficit in tin now with growing demand and scarcity of tin supply that is projected to continue for a considerable period of time.
Given tin's scarcity, alleviation of a historic deficit in tin with expansion of brownfield deposits or new discoveries will not come readily. New discoveries are the lest likely.
With the highest tin grades globally, ample and expanding high grade reserves, low AISC, and cash on hand, Alphamin is the one most significant tin producers in a position to capitalize on the deficit. Alphamin can mill a lot small amount of ore to produce the same amount of tin as other producers.
Here is a comparative chart of Alphamin's tin mineral resource grade on page 8 of Cornish Metals presentation:
