We also have the West facility, which is a conventional underground potash mine that is not in operation and is in care-and-maintenance mode.
−Removed: In May 2019, we acquired certain land, water rights, and other related assets from Dinwiddie Cattle Company.
−Removed: We refer to these assets and operations as "Intrepid South." This property, located in Lea County in southeastern New Mexico, is comprised of 22,154 surface acres, 27,868 acres of BLM grazing leases and 10,097 acres of pending State of New Mexico grazing leases.
+Added: We also operate Intrepid South located in Lea County in southeastern New Mexico, which is comprised of 21,834 surface acres, 27,868 acres of BLM grazing leases and 10,097 acres of pending State of New Mexico grazing leases.
+Added: In March 2020, we sold approximately 320 surface acres from our Intrepid South property, reducing our surface acre ownership from 22,154 acres acquired at the time of purchase, to the 21,834 acres we operate today.
We control the rights to mine approximately 143,000 acres of land northeast of Carlsbad, New Mexico.

Proven and Probable Reserves
−Removed: Our potash (produced from sylvite ore) and langbeinite (marketed as Trio ® ) reserves each have substantial life, with remaining reserve life ranging from three years to over 100 years, based on proven and probable reserves estimated in accordance with SEC requirements.
+Added: Our potash (produced from sylvite ore) and langbeinite (marketed as Trio ® ) reserves each have substantial life, with remaining reserve life ranging from four years to over 100 years, based on proven and probable reserves estimated in accordance with SEC requirements.
This lasting reserve base is the result of our past acquisition and development strategy.

As a result of the Agapito 2020 review, langbeinite reserves decreased in the East mine and sylvite reserves increased in the West mine compared to previously reported reserves.
−Removed: The change in reserves was primarily due to the reclassification of reserves in the 3rd and 4th ore zones from langbeinite to sylvite.
+Added: The change in reserves was primarily due to the reclassification of reserves in the 5th ore zones from langbeinite to sylvite as a result of the cutoff grade increasing.
The cutoff grade for langbeinite also increased, thus decreasing reserves.
The HB mine reserve estimate decreased due to depletion for 2020 production from the HB mine.
−Removed: The Moab property reserves are based on Agapito's 2018 mine reserve estimate adjusted for depletion for 2019 production.
+Added: The Moab property reserves are based on Agapito's 2018 mine reserve estimate adjusted for depletion for 2020 and 2019 production.
The Wendover property reserves are based on Agapito's 2018 brine aquifer reserve.

If we decided to produce potash from our East and West mine sylvite ore reserves in the future, we expect that we would reopen the West facility and be required to construct a new plant to replace the East sylvite plant closed in 2016 to process the remaining reserves.
−Removed: Calculated mine lives that exceed 100 years are reported at 100+ years to balance the reserve life with the uncertainties
−Removed: associated with those extended time frames.
+Added: Calculated mine lives that exceed 100 years are reported at 100+ years to balance the reserve life with the uncertainties associated with those extended time frames.
We currently do not report more than 30 years mining life for Wendover due to the uncertainties associated with natural brine‑containing aquifers.
