Approximately 600 meters of drifts and raises were developed from two
adits and a two-stamp mill was built.
Likewise, the rocks immune to erosion with the
adit anomaly is observed in the central part of the profile (100 m-215 m).
The geological and geotechnical investigations were accomplished through geological mapping, core drilling at different locations, geophysical surveys, excavation of two
adits, in-situ testing in the
adits and laboratory testing.
Luiz Henrique Lessa, the association president, said, 'The transition of
ADIT from a regional to a national organization in 2010 has opened the door to even greater opportunities for both the organization and those in attendance.'
Adit is the Newcastle-based public sector agency established to encourage best practice in UK public sector ICT procurement.
The work was conducted in an abandoned mine drainage
adit on the edge of Dartmoor, Devon, UK (SX 513787).
The Partnership approached government broadband and IT agency
Adit North-East to use its specialist knowledge and contacts to find a supplier capable of providing business class, or SDSL, broadband.
Adit is managing the project which will upgrade all of the region's telephone exchanges for broadband.
The property includes the El Transito Gold Deposit, which is reported from previous trenching, diamond drilling and underground sampling via an
adit, to contain a resource of 618,500 tons grading 5.71 g/t Au (0.16 oz/T) and 27.02 g/t Ag (0.79 oz/T).
"If the mine workings were on a hill, they would drive a horizontal tunnel [called an "
adit"] at the base of the hill beneath the mine workings and let the tunnel drain all of the groundwater.
He further committed Rio to "rehabilitate that area" and said the company would "block off the
adit" (the mine entrance).
At a site near Hope in Shropshire County, a collapsed mine
adit had filled with water causing localized subsidence and temporary closure of a nearby roadway.
