There are continuing developments in underground narrow vein mining, from innovative mining methods using low-profile equipment to adaptations of current mining methods using equipment such as road-headers. The development of new mining methods and mining equipment has one purpose in mind - to extract narrow reef orebodies keeping dilution to a minimum, whilst maximising mining recovery.

Panning for Gold. The standard gold pan is made of stiff sheet iron and is 35cmin diameter at the top and 5-6cm deep. The rim is flared outward at an angle of about 50 degrees from the vertical. Smaller pans are used for testing, and it is advisable for most panners to use either a 30-40cm size for handling ease.
Quartz is a valuable ore for beginners, having no tool requirement. This ore can be found in the Space and Main Realm. Its ore are shaped to be four-pointed stars scattered in the stone. It is a precious material thats more expensive than gold and silver and helps new players kick-start their Mining Simulator journey.
Techniques include extracting gravel straight from the river bed to sinking small shafts to Shafts sunk on quartz reefs or gold bearing ore often encountered returned about 40 ozweek, still profitable, but reflecting the mundic ore. Dargues were crushed but quartz or reef mining was now viewed as a thing of the past. More detailed

Solid quartz reefs of up to 12m wide have been recorded. Shoots of enriched gold mineralization occur as defined zones along the quartz reefs. Grades of up to 3 ozt are commonly recorded. The recorded widths of mined gold enriched quartz are generally between 0.6m -t 1.5m and shoots have been recorded up to 100 m in length.

The reef above the true footwall or below the hanging wall is then lifted or dropped and collected. The ore is shattered but not displaced and only the reef material is transported to the surface. The principle of this mining method is stowing or packing of waste material in
If you are looking for quartz reef gold then you are looking for structurally controlled features as likely as not. These need mapping at the surface, if you have exposure. If not, then you need a geophysical method that will distinguish the gold-hosting structures from the bedrock I would start by digging costeans across the likely structures ...
Large mining companies moved into the area and took over from the individual miner with quartz reef and deep lead mining techniques. The arrival of steam powered machinery and the railway network, expanded the regions timber industry and provided a boost to sleeper and firewood production. 1889 to 1902 The depression hit the area.
The old timers commonly used rail and mining cars to move gold or silver ore and waste rock, and this method is still used in some smaller mines. Most modern mines however, use rubber tired diesel powered equipment to haul ore underground. In a well-designed system, broken rock from a stope will drop directly into the haulage equipment.
settlements associated with both alluvial and reef mining. Individual settlements were spread over a considerable distance of rugged and broken terrain. As will be seen from both the historical, geographical and archaeological evidence, however, they seem to be linked as there was much movement of persons, equipment and even buildings between them.
