INTRODUCTION
Two areas in northeastern Tasmania, the Blue Tier area and the Rattler Range -Mt. Victoria - Mt. Maurice area, have undergone preliminary assesssments for mineral resources at the request of the Mining Forum (Figure 1).
Details of methodology and definitions of mineral resource potential are to be found in the first volume of this series (Mineral Resource potential assessments of selected areas in Central to Southern Tasmania) and in Appendix 1.
These results are preliminary compilations of the more important geological studies in the areas, and assessments of the adequacy of these geoscientific databases. This work does not purport to be complete, and does not include any reinterpretation or synthesis of the data
SUMMARY
These areas are considered to have a very high potential for economic deposits of tin, tungsten, gold and building stone (granite), as all of these commodities have been mined within in close to the areas. There is also a low to moderate potential for rare earth minerals, uranium, molybdenum, copper, clays, gemstones, beryllium, lithium, feldspars and topaz, and an unknown potential for many otlier commodities, including base metals, oil shale, coal and zeolites
The Blue Tier area has been adequately mapped and moderately well explored for tin, but there is still significant potential for many of the above commodities.
The Rattler Range - Mt. Victoria - Mt. Maurice area requires much better geological, geochemical and geophysical surveys over most of the area, as the present databases are inadequate for the determination of mineral potential.

(b) Geological Summary (Figs. 2 and 3)
This area is covered almost entirely by alkali granites and adamellites of the Blue Tier Batholith, of probable upper Devonian to lower Carboniferous age They are partly greisenised in the upper levels, with greisen sheets and veins Overlying the granitoids, in a small area around Mt. Littlechild in the Southwest of the area, are Tertiary basalts and, in a very small outcrop near Mt. Littlechild, sediments of the Parmeener Supergroup (Permo-Triassic).
(c) Geophysical Coverage (Fig. 4)
Gravity station coverage is in the regional category, with stations spaced at approximately 1 station per 8-9 sq. kml . Aeromagnetic data was derived from flights at a spacing of about 1.5 km, and would also be classed as regional^. Airborne radiometric surveys were conducted in the area in about 1969, and followed up by some more detailed ground surveys^.

(d) Geochemical Coverage
Geochemical stream sediment surveys (Cu, Pb, Zn, Ag, Bi, Mo) were undertaken on a regional scale by Geophoto Consultants, but records are poor4. Amoco also conducted regional stream sediment surveys (Cu, Zn, Mo, Mn, As, Ba, Ag, F, Au, As, W) over the northern part of the area^. More detailed surveys (rockchip and soil) have been conducted in and about specific mines and prospects by exploration companies as mentioned below.
(e) Drilling Coverage
The area has been drilled extensively by mining and exploration companies, mostly with relatively shallow (rarely > 200m) percussion and diamond drilling6>7. Most of this was in and around the hard rock mines and prospects, but some was in alluvials^.
(f) Mineralisation
The area is extensively mineralised, with 56 known tin ± tungsten deposits within or in close proximity to the area (Appendix 1; Fig. 5). Most of these deposits were relatively small detrital deposits, derived from weathering of greisen veins, pipes and sheets; some represent veins or alluvial deposits. Amongst the most important of these deposits is the Anchor mine, peripheral to the area but recently operational. Others within the area include the Crystal Hill, Don, Liberator, Moon, Kent, Summit, Australia and Mt. Michael mines.
Other commodities known to occur in significant quantities in the granitoid rocks include uranium (eg. Anchor Mine), thorium and rare earth minerals (monazite), topaz, fluorite, copper (sulphides, eg. Anchor Mine), beryllium (beryl and phenakite), lithium (zinnwaldite), mica and feldspar. No serious attempts to mine any of the above are known, although exploration companies have recognised some of the potential, and assayed for some of these

minerals^. Gemstones (sapphires, topaz, chrysoberyl, quartz varieties and black spinel) are apparently recovered by collectors from Cainozoic alluvium in the area (eg. Wyniford River), but little serious work has been undertaken on these. The sources of these are uncertain.
(g) Previous Mineral Exploration
This area has been the site of extensive mining operations, with large quantities of tin being produced by many small miners between about 1880 and 1950. The Anchor Mine, just outside the area of interest, was reopened recently.
Prior to 1970, the area has been explored by a number of companies, including Mt. Lyell Mining and Railway Co., Electrolytic Zinc Co., Austminex and Aberfoyle Devt. Co., mainly for tin. Apparently none of these efforts resulted in any mineral production. The exploration licences held since 1970 are summarised below:
EL 6/68 (Geophoto Resources Consultants, Texins Devt. Pty. Ltd.)
This lease covered a relatively large area, including most of the Blue Tier area. Surveys conducted included some intensive drilling, detailed and regional scale geological mapping, regional stream sediment geochemistry and airborne radiometric surveys 10. Detailed geochemical surveys were conducted about the Australia, Summit, Liberator, Moon and Michael mines, and the Frome River area. Al l of these hardrock (greisen-vein) prospects were deemed too small and/or low grade to be of interest, and it was considered that, while some potential existed, the other mines in the area would be similarly subeconomic. Vein style deposits were found to be of high grade but low tonnage. Small mineable reserves of alluvial tin were located in the Wyniford River area, but evaluation and exploration by drilling was found to be too expensive to justify.
9/76 (Hellyer Mining & Exploration Pty. Ltd.)
This lease was taken up in an attempt to both extend the known reserves of tin mineralisation in and about the Anchor Mine, and to explore for other similar deposits in the area. Following an extensive drilling program, plus soil sampling and mapping, the potential for hidden tin greisens was assessed as l o w l l . IP and radiometric surveys appeared ineffective at delineating orebodies.

19/78 (Aberfoyle Exploration Pty. Ltd.)
This company explored for tin around the Cream Creek, Spinks and FB (Nicholls) mine areas. Surveys included rockchip geochemistry, percussion drilling and some geological mapping. The area was leases were relinquished due to the apparent limited potential, low tenor of greisens, and remoteness of the area!2.
32/82 (Amoco Minerals Aust. Co.)
Geochemical sampling (stream sediment) and geological reconnaissance over the northern part of the area failed to locate any significant tin-hosting greisen sheets 13.

ASSESSSMENT (Fig. 3)
(a) Quality of data
The area has been mapped, relatively recently, at the satisfactory scale of 1: 50,000.
Gravity station coverage and aeromagnetic data are in the regional category. Airborne radiometric surveys were conducted prior to 1970 but records are poor, flight paths are poorly constrained, and the data may be dated. More detailed and up to date aeromagnetic, radiometric and gravity surveys are necessary prerequisites for a more accurate mineral resource assessment.
Geochemical stream sediment surveys were undertaken on regional scale by Geophoto Consultants, but records are inadequate^. Amoco also conducted regional stream sediment surveys over the northern part of the area^. More detailed surveys have been conducted about specific mines and prospects by exploration companies as mentioned above. Most of these surveys were restricted in the number of elements assayed for.
The drilling coverage is probably adequate, although not to any great depth.
(b) Preliminary listing of possible resource models
A discussion of confidence levels is given in Appendix 1.
Numbers (e.g. CS 15a) refer to the ore deposit models of Cox & Singer (1986) where applicable.
Metallic Resources
1. Greisen and vein-hosted tin-tungsten ± copper, molybdenum, uranium and bismuth (Anchor style mineralisation) in Devonian granitoid rocks (CS 15a, 15b, 15c).
2. Tin ± Rare earth mineral placers in Quaternary sediments (CS 39e).
3. Molybdenum and/or copper in granitoids (? Porphyry: CS16,21a, 21b; Mt Stronach or Mt. Maurice Mine style?).

4. Polymetallic veins in granitoids (CS 22c).
5. Gold in granitoids (Ketza River or Lisle style ?)
6. Rare earth minerals (florencite - crandallite group), of uncertain origin, in clays underlying Tertiary basalt (Legerwood style occurrence)
The confidence level is veiy high for the greisen and vein-hosted deposits (1, 6), due to the abundant known mineralisation of this type in the area. The placer deposits (2) also have a high potential, but tonnages are likely to be rather low due to the restricted distribution of Cainozoic sediments (e.g. Wyniford River). The prospectivity for (3), (4), (5) and (7) is unknown but probably low as few indications are present, although little specific exploration has been undertaken.
Non-metallic, fuel and other resources
1. Geothermal energy in Devonian granites.
2. Building stone in Devonian granites and Tertiary basalt.
3. Construction materials in granite and basalt.
4. Zeolites in Tertiary basalt or pyroclastics.
5. Brick clay and kaolin in weathered and altered Devonian granites (Tonganah or Cornwall style).
6. Gemstones (sapphires, etc.) in Quaternary alluvium.
7. Uranium in sandstones of the Parmeener Supergroup (CS 30c, analagous with equivalent deposits in South Africa).
8. Uranium and Rare earth minerals (monazite group) in altered Devonian granites and greisens.
9. Industrial Minerals (Beryllium, lithium, feldspar, fluorite, topaz and micas) in altered Devonian granites and granite pegmatites.
Model (1) has apparently not been tested in the area, but should have some potential due to the granites inherent radiactivity. Model (2) has not been tested

in the areal°\ so it has unknown prospectivity.The confidence level is very high for construction materials (3), with several workings in the area. The minerals in (4), (5), (6), (8) and (9) are known to occur in signifcant quantities in the area, so they have a moderate potential, despite little specific exploration. The potential for (7) is low due to the restricted distribution of the Parmeener Supergroup, and poor results from radiometric surveys, although the granites would provide good source rocks.

(b) Geological Summary (Fig. 1)
The oldest rocks exposed in the area are the Mathinna Beds, quartzwacke turbidite sequences of (?)Ordovician - Devonian age. These are intruded and locally metamorphosed by granitic to dioritic rocks of the Scottsdale and Blue Tier Batholiths, of probable upper Devonian to lower Carboniferous age. These rocks were all overlain by sediments of the Parmeener Supergroup, now largely removed by erosion except in some of the more elevated areas, particularly about Mt. Victoria. Jurassic dolerite has intruded these sequences as sills and dykes, but is relatively uncommon in this area. Tertiary basalt flows may have covered part of the area, but are now rarely preserved. The river valleys are frequently partly filled with Cainozoic alluvium, probably Tertiary in part.
(c) Geophysical Coverage
Gravity station coverage is in the reconnaissance category, with about 1 station per 50 sq. km. 17. Aeromagnetic data for most of the area was derived from

flights at a spacing of about 1.5 km, and is assessed as regionally. A small southern part of the area was flown at greater detail (about 400m spacing) by the Electrolytic Zinc Co.in 1959, although this is now rather dated data 19 An Airborne Radiometric survey flown by Geophoto Resources Consultants in about 1969 covered part of the area^O, but the data appears to be poorly constrained and recorded^!.
(d) Geochemical Coverage
Geochemical stream sediment surveys (Cu, Pb, Zn, Ag, Bi , Mo) undertaken on a regional scale by Geophoto Resources Consultants covered the eastern part of the area, but records are poor22. Union Corp. also conducted regional stream sediment surveys (Sn, W, Mo, Cu, Pb, Zn) and some rockchip surveys (mostly Sn) over the Rattler Range area23,24. Relatively comprehensive stream sediment surveys (Sn, W, Mo, Cu, Pb, Zn, Ni , Bi, Au, Ag, Sb, As) were conducted by CSR in the Mt. Maurice area25. More detailed surveys (rockchip and soil), for limited commodities (e.g. gold or tin), have been conducted in and about specific mines and prospects by exploration companies as mentioned below.
(e) Drilling Coverage
The Mt. Paris Tin Field has been drilled (percussion) extensively by mining and exploration companies, but little or none of this was in the area of contention. Some drilling has also been done in the gold mining areas, but again apparently not within die area of contention. The subsurface geology thus is poorly known.

(f) Mineralisation
The area is locally highly mineralised, with at leastl6 known tin deposits, 185 known gold deposits, andl2 miscellaneous deposits within or in close proximity to the area (Appendix 3 and Fig. 5).
The Mount Paris Tin Field is immediately adjacent to the area of contention, particularly the Star of Peace, Mammoth, Rattler, Welcome and Bells Hil l workings. It is quite likely that some of these workings were within the area. Most of the tin deposits were relatively small detrital or alluvial deposits, derived from weathering of greisen veins, sheets and pipes, quartz veins and stockworks, formed near the roofs of alkali granites.
There are two goldfields overlapping the area, namely the Alberton - Mt. Vicoria and the Dan Rivulet Fields, plus some other sporadic occurrences. Gold occurs in numerous quartz veins in the Mathinna Beds, usually small and rich, but erratic in size and grade. It also has been recovered from placer deposits in associated Cainozoic alluvials, which have not been well tested. Most of the mining was done in the period 1860-1920, but sporadic prospecting and small scale mining continues to the present day. Some of the more important deposits within the area of contention include the Strickland, Una, Hinemoa, Southern Star, Bright Star, Esk, Mt.Victoria, Caxton, Scotchman, Beckers and Struggle workings, and there are a large number just outside the area.
Granite has been quarried for building and ornamental stone in several parts of the Scottsdale Batholith close to the area of contention, and the Mt. Maurice area is considered highly prospective for such^6.
Copper + tin + bismuth prospects occur near Mt. Maurice, and appear to be relatively small veins but little detailed exploration has been conducted in the area.
(g) Previous Mineral Exploration
This area covers part of the Alberton - Mt. Victoria - Dan Rivulet Gold Field, which has been the site of numerous small mining operations, with large quantities of gold being produced by many small miners between about 1860 and 1920.
The principal exploration licences held over the area are summarised below:

This company flew airborne Aeromagnetic surveys over the southrnmost part of the area, but appear to have done little else within the area27.
EL 6/68 (Geophoto Resources Consultants, Texins Devt. Pty. Ltd.)
This relatively large lease covered some the eastern part of the area, including most of the Mt. Paris area. Surveys conducted included some intensive drilling, detailed and regional scale geological mapping, fracture analysis, regional stream sediment geochemistry and airborne radiometric surveys28. Detailed geochemical surveys were conducted over the tin greisens of the Bald Hill - Star of Peace area. These hardrock (greisen-vein) prospects were deemed too small and/or low grade to be of interest, and it was considered that, while some potential existed, the other mines in the area would be similarly subeconomic. Alluvial gold in the Dan Rivulet (pardy in the area?), was not fully tested but grades were low and erratic, and evaluation and exploration by drilling was found to be too expensive to justify.
SPL 107 Geopeko
The Una - Strickland - Hinemoa mine area was evaluated using rock chip assays and found to have little potential for mining29
EL 31/76 ACA Howe Aust. Pty. Ltd., Mineral Holdings Aust. Pty. Ltd.
Lodes in the Dan Rivulet area were found, by limited mapping and rockchip geochemistry, to be erratic and with only minor gold concentrations^O.
EL 11/77 Union Corp., Mineral Holdings, Newmont, ICI, CRA, Amax Aust.
Exploration around the Rattler tin prospect in the northeast, using drilling, costeaning, geochemistry (soil, rock chip and stream sediment) and geological mapping, found several large tin-anomalous areas, but with thick overburden and low grades31>32.

A preliminary investigates of some of the mines of the Alberton Gold Field, using rockchip geochemistry33.
EL 21/80 Union Corp., Mineral Holdings
Regional stream sediment geochemistry, followed up by reconnaissance geological mapping in the Rattler Range and Mt. Maurice areas, identified no significant new anomalies.34
23/82 Oceana, Renison Gold Fields
Exploration with geophysics of alluvials in the New and Dorset Rivers suggested some prospectivity for gold and tin35. Sampling and assaying was carried out in the old mines. The lease was dropped in favour of mining leases.
43/82 CSR
This licence was explored with a relatively comprehensive stream sediment geochemistry survey, geological mapping and some more detailed rock chip assays in various areas36.
EL 17/86 Goldfields Exploration Pty. Ltd.
Reconnaissance mapping and rock chip geochemical surveys were undertaken in an attempt to delineate bulk mineable gold ores in the Alberton, Dan Rivulet and other areas37. The Dan Rivulet area was considered to have potential.

ASSESSSMENT (Fig. 3)
(a) Quality of data
A small part of the area (on the Ringarooma sheet) has been mapped, relatively recently, at the satisfactory scale of 1: 50,000. Another small part of the area (on the Launceston sheet) was mapped at 1:63,360, prior to 1964, and this is now outdated information. The bulk of the area is on the Alberton !:50,000 sheet, being mapped at present. The geological knowledge of this are must, therefore, be considered as inadequate until mapping is complete. The geology of the Mathinna Beds is particularly poorly known, due mainly to poor outcrop and lack of marker beds. The structural controls on the gold mineralisation are also poorly understood.
Gravity station coverage is in the reconnaissance category, and aeromagnetic data in the regional category. Some of the Rattler Range area was probably covered by airborne radiometric surveys, but these are poorly recorded and rather dated.
Geochemical surveys are good for the western (Mt. Maurice) and northeastern areas (Rattler Range), but rather poor and erratic in quality for the rest of the area.
Drilling coverage is poor to nonexistent.
(b) Preliminary listing of possible resource models
A discussion of confidence levels is given in Appendix 1.
Numbers (e.g. CS 15a) refer to the ore deposit models of Cox & Singer (1986) where applicable.
Metallic Resources
1. Greisen-hosted and vein style tin-tungsten ± copper, molybdenum and bismuth in Devonian granitoid rocks (CS15a, 15b, 15c; Anchor style, Rossarden and Storys Ck. style mineralisation)).
2. Tin ± gold ± Rare earth mineral placers in Quaternary sediments (CS 39a, 39e).
3. Molybdenum and/or copper in granitoids (? Porphyry style: CS16, 21a, 21b; Mt Stronach or Mt. Maurice Mine style?). >
4. Polymetallic veins in granitoids (CS 22c). >
15
5. Gold in granitoids (Ketza River or Lisle style ?)
6. Gold in quartz veins and stockworks in turbiditic sediments (CS 36a).
7. Rare earth minerals (florencite - crandallite group), of uncertain origin, in clays underlying Tertiary basalt (Legerwood style occurrence)
The confidence level is very high for the greisen and vein-hosted deposits (1, 6), due to the abundant known mineralisation of this type in the area. The placer deposits (2) also have a high potential, but tonnages are likely to be rather low due to the restricted distribution of Cainozoic sediments. The potential for (3) may be moderate in the Mt. Maurice area. The prospectivity for (4), (5) and (7) is unknown but probably low as few indications are present, although little specific exploration has been undertaken.
Non-metallic and fuel resources
1. Geothermal energy in Devonian granites.
2. Building stone in Devonian granites and Tertiary basalt.
3. Construction materials in granite and basalt.
4. Zeolites in Tertiary basalt or pyroclastics.
5. Brick clay and kaolin in weatliered and altered Devonian granites (Tonganah or Cornwall style).
6. Gemstones (sapphires, etc.) in Quaternary alluvium.
7. Uranium in sandstones of the Parmeener Supergroup (CS 30c, analagous with equivalent deposits in South Africa).
8. Uranium and Rare earth minerals (monazite group) in altered Devonian granites and greisens.
9. Industrial Minerals (Beryllium, lithium, feldspar, fluorite, topaz and micas) in altered Devonian granites and granite pegmatites.
Model (1) has apparently not been tested in the area, but should have some potential due to the granite's inherent radiactivity. Model (2) has'very high
1 6
prospectivity in the area38. The confidence level is very high for construction materials (3), with several workings in the area. The minerals in (4), (5), (6), (8) and (9) are known to occur in signifcant quantities in the area, so they have a moderate potential, despite little specific exploration. The potential for (7) is low due to the restricted distribution of the Parmeener Supergroup, and poor results from radiometric surveys, although the granites would provide good source rocks.
