Ken,

A “mineral rock,” at least as I use the term, is a Trophy Rock.  Trophy Rock is simply a “rock” mined from a deposit of sea minerals in Utah.  There are only three such veins of salt sea minerals known in the world.  In other salt deposits, the minerals settled out and left just salt.  Each of the known salt sea mineral deposits have a slightly different composition.  I like the mineral composition in the vein that Trophy Rock mines in Utah.  It is 100% natural and a great blend of 60+ minerals that benefits deer.

Growing Deer together,
