I owned OBM Ora Banda great ground & great manager. They had big trouble getting used tired mill to work . That mill had produced a lot of gold . A temporary portable mill like the Gekko would be very limited in capability. You need a serious mill for throughput. That's why you commission a company to carry out that work, they know what will work & what won't work, you don't commision a teenager to do it . I predict the Gekko will be disposed of surplus to needs.
