The Environmental Compliance Consultancy has withdrawn its services from Headspings Investments.
Headspings Investments, a Namibian registered Russian-owned mining giant, Uranium One Group, hopes to start mining uranium in the South of Namibia.
ECC says it has completed a detailed report following the finalisation of public consultations for the mining group.
The report also contains terms of reference for a specialist groundwater study.
Uranium One has been receiving backlash from certain sectors regarding the in-situ mining method it wants to use to extract the mineral.
The mineral orebody is found under fresh underground water, and some say the proposed mining style could be hazardous to the environment and potentially contaminate the underground water.
The mine officials have, through various information sessions, refuted these claims, stating that the in-situ mining style is the safest form of mining.
ECC and Headsprings have stated "irreconcilable differences" as the reason for their divorce.
Last year, the Ministry of Agriculture, Water and Land Reform revoked two prospecting licenses for the company to drill 37 exploration boreholes.
These licensees have not been renewed yet, bringing the exploration operation to a standstill.
In a letter dated November 9, 2021, the ministry told the company that the government was cancelling the deal because it had identified gross negligence.
