We mine our Red Lake Diatomaceous Earth with Calcium Bentonite (Red Lake Earth) from a deposit in the pristine province of British Columbia, Canada. Unlike other DE products, both of these sought-after minerals are found in their natural state within this deposit. This natural combination is rare, with only one other known deposit that contains both diatomaceous earth and calcium bentonite in the world. Red Lake Earth Diatomaceous Earth with Calcium Bentonite is OMRI Listed in the United States for use in organic production.
