Piura Life and Agriculture and NGOs partnered together to form some counterarguments against the Canadian mining company's claims that it would cause little or none environmental damage. They stated that the mining project could cause deforestation because of the immense amount of water and needed to mine; pollution that may affect the water supply and nearby rivers, such as El Niño and Piura, that could be consummated; and farming production would suffer because of the environmental effects incurred. They deemed these environmental risks "too high to be ‘acceptable." Skeptical about the environmental study of the project the government would produce, OXFAM commissioned its own report and came to the same, aforementioned conclusions and described how the government's methodology and approach was wrong. Concerns were also raised about the government's neutrality in the course of dispute between Tambogrande and Manhattan Minerals, as the government owned 25% of Manhattan Minerals.
