TO WHOM IT MAY CONCERN

Geological and geophysical  experiment in the Dullstroom-Barberton-Badplaas-Elukwetini-Tjakastad-Songimvelo-Ekulindini region.

Dear sir/Madam

I am a professor at the University of Cape Town. We are conducting a geological survey to study the origin of the rocks in this area. The rocks of this region are some of the oldest in the world. Our study is focussed on what these very old rocks ( more than three and a half billion years old) can tell us about how the Earth during that time and how it has change over time; and how we might take improve ways to take care of it now.

To be able to carry out this experiment, we would like to have your permission to access your property, and place in the ground a small piece of equipment with which we can measure the electrical currents in the ground. Our experiments are not destructive and are not harmful. At each site the equipment is left on the ground for 3 days, and is then moved on. All the scientists are instructed to respect the wishes of the property owner and too take special care not to destroy any vegetation or damage fences and roads. Everything will be left in place as it was before we arrive.

I would like to ask for your cooperation and help wherever possible to make this a successful experiment. I will be happy to send you a summary of the results after we finish. I am also happy for me and my colleagues to come and talk to you about our work and findings should this be of interest to you.

Please find attached a short outline of the details of our experiment.

I thank you for your understanding and generosity to help us.

Yours sincerely

Sgn Professor Maarten de Wit
