Mine location stops map
Stop | Location | Zone | |
Number | Stope (floor) | Number | Geologic Feature |
1 | 12/14-SRR (190) | 8 | High grade pollucite core of the Pollucite Zone. |
2 | 16-SNN/SPP (184) | 5/8 | Low Grade Pollucite: a mixture of Pollucite Zone and
Upper Intermediate (Spodumene) Zone.
|
3 | 16-SNN/SPP (184) | 5 | Upper Intermediate Zone - Spodumene-Quartz lntergrowth
(SQUI) after primary petalite .
|
4 | 11-SU (190) | 5 | An approximately 10 metre "Tancocrystic" K-feldspar
crystal in the Upper Intermediate Zone.
|
5 | 9-SP/SQ (190) | 5 | A single petalite pseudomorph; also amblygonite, petalite
and pollucite found in the area.
|
6 | 14-SM (190) | 9 | The Upper Southwest Zone Lepidolite Zone |
7 | 7-H (330) | 7 & 3 | Typical Quartz Zone. Contact with the Saccharoidal Albite
Zone can be observed. The only known location at Tanco where
cleaveable quartz can be seen in situ.
|
8 | 10-H (330) | 2 | Typical Wall Zone displaying megacrystic K-feldspar
crystals.
|
9 | 21-N (305) | 6 | Central Intermediate Zone: the lower portion of a tantalum
zone (O-Zone) in close proximity to a Quartz Zone.
|
10 | |
|
The "Lookout" A good view of room and pillar mining method. |
11 | 12-N (330) | 4 | Banded aplite in the Lower Intermediate Zone in close
proximity to the Central Intermediate Zone.
|
12 | 14-N (350) | 2 | "Hayward's Horse": A xenolith of host metagabbro
(amphibolite) within Zone 20. Such xenoliths generally
generate their own surrounding Wall Zone (Zone 20)
|
13 | Refuge Room | 4 | Typical Lower Intermediate Zone showing diverse (1st Level
Stn.) mineralogy (lithian muscovites, SQUI,
cookeite,K-feldspars, Na-feldspar). |
