Petrological Examination of Core DDH. 1.

Petrology Resnlts.
(1) . No gold was identified in the samples examined in eitherthe dolerite or the underlying Triassic sandstones. These resultscombined w~th no evidece of post mineralisation in either roc~
typ~s Bottrill considered petrologically the gold potentialof the area discouraging. :
(2) One dolerite sample wes normal dolerite in texture,mineralisation and grain size. The other dolerite sample isatypical in these properties with coarse grained magnetiteintergrown with _ pyrite and possible quartz. Bottrill suggeststhat these minerals are xenoliths inclusions from underlyin~
rocks that were caught up in a late stage volatile richporphyritic. dolerite intrusive lIagma, which " may indicatea possible external source for sulphides and gold."

Conclusions.
(1) Gold in Jurassic dolerite and in TriassiC 8ge sedimen ts :in Tasmania is difficult to explain geologically. This is,more difficult where no obvious post mineralisation, hydrothermal'alteration and widespread veining was seen macroscopically;or microscopically in the drill cores. '

On behalf of the princi~als of the above company.Mr Kerry Richardson of K.M. R. Drilling Co. requested thewriter to lithologically log three proposed explorationdiamond drill holes.:
INVESTIGATION PROGRAMME;
These 3 holes were drilled between 20-23rd September1993 USing an Atlas Co Mobile. 8 overhead drive rig andcoring with 1.SmNI core barrel. The writer made areconnaiasance visit to this drilling on 22nd Septemberand collected the report of the previous exploration of1988-1989. Jones 1990. A further visit was made to thesite at the conclusion of- drilling on the 23rd and a surveyof drill holes undertaken. The cores were logged on the2S an.d 26th September and the cores of the 1989 drill'ingexamined on the 30th September.

OBJECTIVES OF THE 1993 INVESTIGATION DRILLING PROGRAMME:
The principals of Evalast Minerals & Hining Pty ltdhave the following objectives in undertaking furtherdrilling in 1993:-
(1) The anomaly ascertained by diviningLazarus on the Palverata Road near Dillionsextends across to Kellaways Creek flood plaintested by drilling.
by Ii r • II .Creek and
be further
(2) The aim of this drilling was to establish if thesame rock sequence found present under the old PalverataRoad by the 1989 drilling extends to the creek.
(3) Given the same rock types and sedimentary sequenceis established then the rocks be assayed for gold.
(4) A subsidiary aim!Hnerals and fHning Co. wasand metallurgical opinions on
of the directors of Evalastto obtain a second geologicalthe prospects of the area.
IV1'th this in view they employedgeology and P.L. James of LauncestonBoth are retired employees of the Tas.
PREVIOUS INVESTIGATION:
the writer for thefor the metallurgy.Dept. of fHnes.
In July 1989, one of the anomalies, the Dillion Creekanomaly was diamond drilled for gold; using NinesDepartment truck mounted L.Q. diamond drill rig. Threeangle holes were drilled at 60· to 12-20 meters. Thelocation of these holes is shown on Fig 2 and resul ts !'ic:3.
This drilling and exploration programme was carrie~
out under the supervision of Mr. P.L. Jones of Phil Jonesand Associates. The assays of the rocks encountered wereundertaken by the Burnie laboratories of Analabs Ltd.
These assay results, lithological logs of diamondholes as well as regional geology, plus a future explorationprogramme etc are covered in a comprehensive report.
In, his summary and recommendations, Jones 1990. states;"Only one anomaly, the Dillion Creek zone has been drilled(3 holes) returning highly encouraging results from onehole assaying 2m of 58 glt Au."
In his evaluation of the exploration potential ofthe licence 94/87 Jones states, "Good potential fordiscovery of possible sediment of structurally hosted golddeposits occurring with in hematitic and graphitic alteredTriassic permeable sandstones, minor siltstones and shales."

TOPOGRAPHY ABO LOCAWIOB OF DIILLIIG,
The 1989 drilling was undertaken on the bend of theold bye passed section of the Palverata Road. These hole;;were located at the foot of the steep southern slope ofthe Kellaways Creek valley. The 1993 drilling was on thenorth side of the existing road, on the narrow, southern,flood plain of Kellaways Creek, fig 2.
REGIONAL GEOLOGY;
Farmer 1981, mapped the lower (ellaways Creek area asa lower Triassic Age sedimentary sequence of dominantlymedium to coarse grained quartz sandstones with subordinatemudstones and minor clay pell.tbeds. These Triassic age'sediments overlie felspathic sandstones with subordinatemudstones of the Ferntree Formation of Permian Age. Bothmapping units of these sediments belong to the Parmeersuper group of sediments of Permian and Triassic ages.
Quartzose and graphiticas Triassic age sedimentsbank immediately west of the
sandstones and mudstones mappedoutcrop on the 3m high roeddrilling.
Overlying the valley floor sediments are thick sillsof dolerite forming the high ridges of Kelleways Creekvalley. Farmer shows the sediment dolerite contact asconformable in the vicinity of ehe drilling area.

In all three holes drilled a soil horizon of alluvialsilts. with some fine river gravels at the base.
These Recent deposits overlie highly weathered Triassicquartzose sandstone and lor slightly weathered doleriteof 'Jurassic age. In this section of the drill holes highdrill losses were experienced. Because of this thethickness and structure of the dolerite is difficUlt tointerpret

COMPARISON OF THE 1989-1993 DRILLING RESULTS:
1989agesets
The core loss of the 1993 was less than that of the'drilling. Eoth the dolerite and the lower 'i'riassic
sandstone sequence is lithologically similar in botl,of drill hol'es.
MINOR LITHOLOGICAL DIFFERENCES BETWEEN DRILL HOLES:
Minor lithological differences exist between all drillholes of both programmes. Such differences are to b~
anticipated and are found in other areas where Triassicsediments outcrop in S.E. Tasmania. Rapid changes in currentdirections and depositional conditions "ithin shortdistances are features of these fluvial and lacustrinesediments.
The differences observed were:-
(1) The hematitic alteration and banding seen in hole:1 to 3 is not present in holes 4 to 6. The only majorhematitic alteration seen in these holes is that a"'the red mudstone at 32 to 34 meters in DDH.5.
(2) Graphitic bedding both thick and fine is more COmElOIlin the 1993 holes than in the 1989 holes. Graphit"which appears to be sedimentary occurs in both seU;of holes, often associated with mudstone fragments.
(3) The correlate horizon of bedded mudstones and closel)'bedded sandstones of DDH 4 and 5 at depths of 17 to23 meters was not reached by the drilling of 1989.The holes "ere too shallow. The horizon also probablydips belo" DDH. 6 to the "est.
(4) The coarse sandstone and grit band of DDH.6 at 14 to18 meters depth with sedimentary pyrite, biotite,graphite and clay pellets is not present in any o~
the other five holes.

GEOLOGICAL SOURCB OF THB GOLD:
In the Cygnet area, the source of the gold isconsidered to be the alkaline, intrusive rocks, namelysyen,ites of Cretaceous age. The syenites generally intrudeas dyke swarms in the Permian age sediments rather thanTriassic sediments.
No syenites and no veining vas present in the cores'of the 1989 or 1993 drilling. In addition the pyrite andgraphite found in the coarser sediment of DDH. 6 appearsto be sedimentar,y and secondary. The only, mineralisationr'ecognized was the thin veinlets [< lmm], in the doleri teof DDH.I
The assay of his dolerite and the sandstone aboveof the 2 meters sampled gave an exceptionally high valuefor gold of 59.2 g/t. In the underlying sandstone sequencethe assays values at 2 meter intervals were 1.23 g/t.declining to 0.20 glt and 0.11 g/t. Fig 3.
POSSIBLE ALTBRNATIVE BXPLANATION rnA' ADOLERITE SILL:
A thin dolerite sill intruding at the top of thesandstone sequence appears to be the most likely structuralexplanation, for the dolerite in the 6 holes drilled: withresidual surface weathering accounting for the high assay,values of DDH.I.
With core recovery so low in all holes near thesurface and the presence of fine river gravel at the baseof the dolerite in some of the holes may indicate thedolerite and the sandstone above it are boulders. Thegravels appear to be embedded in the ~oft sandstone surfaceand because of th~s are not thought to be drillinccontamination from higher up the holes.
Pleistocene gravels are common in the Kingborougllsheet area from tslus slides or coarse river gravels. Aboulder layer would explain the one dolerite peice of corewi th the mineralised veinlets and the large jump in theassay values of the top sample of DDH 1.
CONCLUSIONS:
(l) The rock types found in the six holes are the samelithologically and the sedimentary sequence appears tobe the. same stratigraphic level for both the 1989 and 1993drilling.
(2) No definitive explanation for the presence of goldparticularly the values of DDH.I was gained from the loggineof the cores. If the gold extends north of the origionsl1989 drilling, it is likely to be very fine grained andassociated with graphite.
(3) From the geology alone no prediction of the gold valuesis possible for the 1993 drilling.

Petrographic examination of some diamond drill core
from EL 94/87, in the Pelverata area,
for indications of gold mineralisation,
for Evalast Minerals & Mining.
R.S. Bottrill
5/5/94
Introduction
Background
Several diamond drill holes have been drilled in the Dillons Ck. prospect, nearPelverata, to test a possible gold occurrence, delineated by divining techniques.Some very encouraging results have been returned, including 2m @ 58 glt Au and2m @ 1.23 glt Au (Jones, 1990). These assays were of samples of quartz silt,Jurassic dolerite and Triassic sandstones and arkose. No obvious macroscopicvisual indications of gold mineralisation have been identified to date.
Objective
The objective of this study is to determine if any microscopic indications ofgold mineralisation are present.
Petrographic examination
The core was examined macroscopically and no obvious indications of goldmineralisation (eg. quartz veining) were detected. The core consists of dolerite andsandstone. Four representative samples were prepared as polished thin sections forstudy, under the polarising microscope, to identify any gold mineralisation and/orassociated indicator minerals, hydrothermal alteration, etc.
Sample No. C107495 (PT89-1. 5.2 m)
This sample consists of Jurassic dolerite, of typical mineralogy, texture andgrainsize (-0.5-1 mm). There is dominant plagioclase (-45%), abundant augite(-25%), -5% pigeonite and about 25% mesostasis. This fine grained brownmesostasis contains abundant fibrous alkali feldspars and fine grained magnetite«0.5 mm), minor pyroxene needles, quartz and clay-like phyllosilcates

(celadonite7), and a trace of very fine grained chalcopyrite. There is no Indication ofany post-pnellIDAtolitic hydrothennal altcl'ltiOll or gold-related mineralisation.
Sample No. CI07496 (PT89-1. 6.3 m)
This sample consists ofJurassic dolerite, of rather atypical texture.mineralogy and grainsize. There is about ISl.iplagioclase, 15% augite, -2-5%pigeonite, ~5% magnetite, - 1% pyrite and about 50-60% mesostasis. Thepyroxenes are unusually coarse, with blades about IOx2 nun in size, and arevariably altered to red-brown phyllosllicates The plagioclase laths are up to 5mm inlength, and are partly micrographically intcrgrowo and replaced by quartzofeldspBthic material. The magnetite is up to Smm in size, abnormally large fordolerite, and is commonly skeletal and intergrown with coarse grained pyrite. plusquartz(?) and other minerals. The white - brown mesostasis varies from granophyric
, to radiating and plumose in texture. and contlins abundant fibrous alkali feldspars,quartz and magnetite. There is also a trace of very fine grained chalcopyrite.
The dolerite is unusual, and appears to rqnseut a late stage, volatile-rich,porphyritic phase of the dolerite. The pyrite and magnetite are conceivablyxenocrystic inclusions originating in underlying rocks and caught up in the l'Ipidlyrising and quenching dolerite; they may have replaced pyrrhotite or another mineral.There is probably insufficient sulphide for pyrite crystallisation from normaldoleritic fluids, although this rock was presumably volatile rich to crystallile thecoarse crystals. The sulphide may also have been derived from reaction'withwalirocks.
There is no indication of any post-pneurnatolitic hydrothermal alteration or goldrelated mineralisation, although the pyrite-magnetite intergrowths may indicate apossible external source for sulphides and gold.
Sample No. CI07497 (PT89-1. 8.3 m)
This sample is a fine to medium grained, well sorted, quartz arenite withquartz cement, rounded quartz grains and about 10% phyllite clasts. There is minorplagioclase, potash feldspar and mica and tnM:es of graphite and fine grained pyrite(probably diagenetic). The siliceous matrix is probably metamorphic in origin.There is no indication of any syngenetic sulphides, hydrothermal alteration. goldrelated mineralisation or any obvious conceotration of heavy minerals.
Sample No. CI07498 (BH 6. 14.5 m)
This sample is a quartz arenite. It contains poorly sorted, fine to very coarsegrained quartz and about 10-15% mudstone and argillaceous matrix. There is a traceof mica, potash feldspar, graphite and pyrite. The pyrite is medium to coarsegrained, euhedral and is often enclosed in quartz and chert grains, which it appearsto replace; it is probably detrital and/or diapDetlc in origin. There is no indicationof any syngenetic sulphides. hydrothermal alteration. gold-related mineralisation orany obvious concentration of heavy minerals.

Appendix 2.
Discussion
The core was examined macroscopically and microscopically, and no goodindications of gold mineralisation (veining, alteration, sulphidation) were detected.The sandstones contain a little detrital and/or diagenetic pyrite, and somesilicification, probably diagenetic or metamorphic. One of the dolerites is normal intexture, the other quite atypical. The latter is porphyritic and contains coarse grainedpyrite-magnetite intergrowths. These are enigmatic and may indicate an externalsoJce of sulphides (and perhaps also gold).
"There is, however, little or no encouragement for the gold potential of the area thatcan be derived from this petrological analysis. If more gold anomalies areencountered during assaying, it may be worthwhile rechecking the splits of thesesamples. .
