The coronavirus (COVID-19) outbreak is disrupting the personal and professional lives of many people all over the world, including the lives of solvers who would like to submit their ideas to this Challenge but they probably need some more time.
For this reason, Rio Tinto has decided to extend the deadline for the “Ore Upgrading” challenge to April 6 at noon, ET. If you have already submitted your entry, you are welcome to edit it during this time.
In this challenging period, it is very important that you and your loved ones stay safe and healthy. And Rio Tinto is still looking forward to receiving your solutions!
