Touchstone Gold's Segovia gold project seems to possess all of the key attributes that you look for, i.e.: large size, low-cost, near-surface, and high-grade, with road, power and water access, and without mine development constraints of population, elevation, or conservation restrictions -
An extract from the 27th. June 2013 Touchstone news release:
Touchstone Gold Announces the Discovery of a New High-Grade Gold Zone at its Segovia Gold Project in Colombia
Toronto, Ontario, June 27, 2013
""We are encouraged by the discovery of another mineralized trend that is similar in size to our Pepas-Filodehambre-1141 zone. Finding the Bonanza Zone enhances the high-grade profile of our land package and increases our confidence in the multi-million ounce potential of our Segovia Gold Project. Touchstone continues to move forward in our pursuit to build a low-cost, near-surface, high-grade gold production scenario" commented David Wiley, President and CEO of Touchstone Gold."

"Segovia gold project
The company’s Segovia gold project is situated in the Segovia-Remedios gold belt in Antioquia, Colombia. The belt is 300 kilometres by 15 kilometres in size and has a long history of gold production dating back to the fifteenth century. It has approximately 24 million ounces of known gold content with production to date totalling approximately 5.5 million ounces.
The land is situated approximately 200 kilometres northeast of Medellín, Colombia. The project site is accessible by road with power and water readily available. Elevation in the area ranges from 210 to 270 metres above sea level (masl)."
