A total of 30 samples were collected from outcrops and old workings
. These samples focused on mineralized shear zones and associated quartz veins, significant results are detailed in Table 1.
- 3m @ 5.4g/t Au from 74m down hole (19MORC008) testing below the old workings
at the Consols Prospect
Every hole intersected strong silver mineralization, mostly adjacent to old workings
, indicating that historic mining focused on very high silver grades and left behind significant high grade silver mineralization.
This work resulted in 50 samples being collected from in-situ outcrops, entrance to old workings
, float and historic waste/ore dumps.
At the time he was last seen, Wilson was on an exploration tour of the old workings
. The Wilsons held some blocks of coal north and east of the slope which they operated on Illinois 37 at Cedar Grove, but these additional holdings had not been operated because of underground water.
The plan is to use as much of the old workings
as possible by rehabilitating and widening sections where possible.
There are patches completely bare, potholes and sunken old workings
Within a few seconds, 650,000 gallons of water gushed in to the mine after the miners and pit manager Malcolm Fyfield blasted through to flooded old workings
"Miners must recognize that multiple seam stress can be encountered from overlying or underlying old workings
where an inspection of the old workings
maps indicates that interaction stresses are not expected," Gauna and Mark concluded in their work.
The 1875 disaster happened when the Lan was flooded with gas from an old workings
In the 1980s, as they were performing reclamation, they looked at all options, rejected bulk-heading and implemented hydrological controls above the portals to prevent inflows into the old workings
. The Red Mountain and Treasury tunnels are still open today and water is flowing from those tunnels, but the water quality is good.
