INTRODUCTION
Nicke1-bearing
sulphideshave been knownto ocowein the Espedalen
area sinoethe 17thcentury. Miningof the sulfidson a large
scaletookplacein the mid 18thcentury, speoifically
between
1846-57and 1874-711.The prinoipalproducingmineswere the
StatsrådStangand EvanøMine.
Interestin the Espedålenarea by A/S Sulfidmalmdevelopedin
1982with the xuisitionof the old •howings. Investigatione
were oarriedout and many of the claimewere dropped. In 1971
a joint-venture
with NorskHydro was eignedand a poolingof
mutualinformation
has resultedin a renewedinteriest
in the
region.
Thås reportie a eummaryof the work thathas oocurredin the
past 10 yeareand is basedon the information
of the joint-venture
participants.
THE EVANSMINE
A eusmaryof the geologyof the Evansmine has bsen completed
by Overwien(1965),and Vokee-Vrålstad
(19891. Essentially,
thay stats$ tha sulfidesone iø flat lyingon the underside
of an ultrabasic
body cut off on both ende by faults. Ths down
dip extensionwas thenunknown. But, in 1971a mise-1-1a-masse
surveyrepartedby A. Sindre(1971)showsthat any sulfidseremainingwouldbe of a smallquantity.
Vbkes-Vrålstad
had assaysof tip materialthatgave .8%Ni to
3.4%Ni.
Basedon the aise-i-la-masee
surveyno furtherwork has been conductedat the Evansmine.
STATSRADSTANG'SMINE
Overwien(1985)statesthat the strike1engthof the Stangmine
is 115 m long,with an east-westdirection.The dip varieøbetween
40 - $00 to the northwith an averageof 500. The workingshave
a depthof 30 m downdip. Some assaysquotedin thipreport aret
.28 - 1.3 % Cu
.65 - 1.2 % Ni
It appearsthat Vokes-Vrålstad
(1969)have reliedheavilyon a
reportby Vogt (1917)and gave a generalidea on the geometryof
the ore sone and the hostrook geology, that is the ore zone
appearsto be lensoidalin shaps,pinchingout at both snde. The
geologyof ths hostrock is anorthosite
in the hangingwall and a
noriteor maficnoritetn the footwall.

RECONHENDATIONSAND CONCLUSIONS
Since 1962, when interest first developedin the Espedalen
nickel province,much work has been done to eliminateareas
that are uninterestingfrom those that are. Showingsat Statsråd Stang, Nicolins,Jørstad, Andreasberg,Dritua and Rywil to
date are areas that warrent further investigation.After
all the
work done so far there are still many unansweredguestions. For
•xample, the lack of good outcroppingof the mineralisedson•
at Jørstad coupledwith a complex EN anomaly does not, in my
opinion, give good groundø fax a drillingprogram.
It is hoped that situationswill soon exist where both concerns in
the joint venturs will be able to conduct a program based on the
followingrecommendations,or a variationof thsm and eliminate
these interestingarese, or go furtherwith a comprehensiveprogram of drilling.
The Evans mine does not warrant furtherwork. However, in
the event productionshould start onee more, the Evans mine
tip could prove useful mill start up material.
The StatsrAd Stang area is one area that reguires more investigations. A re-examinationof the Stang ore body with the misei-la-massemethod, using a variation in electrodepatternø to
eliminatothe effect of conductors,may yield a mors definite
evaluation. Also the test area could be expanded to include the
"S" anomaly and the Nicoline mine. However, if this method
proves unuseful,then consultationshould be sought to •elect
a mathod that would stittleguestionson sise, shape, and location of potentialmetalliferousarsaa.
As accese to this are is relativelygood, it iø felt that the
anomaly "S" area could be further inviestigated
by trenching.
A tractormount•d back hoe can dig a trench 14 ft. desp 2$ ft.
long in one hour. On this basis it is possible that a trench
some 200 ft. long, 3 ft. wide and 3 ft. deep could be dug in
1 hour. This would be guite sufficientto cut the "S" anomaly
axis. Also a trench in the oorrect loaationcould enlighten
the geologicalsituationbetween the Stang and Nicoline mines,
where there is an unoommittedfeelingthat there •xist a complex structure, (This may be revealed by Ryan's mapping).
Tranchingof this nature would settle any guestionsconcerning
geology,structure,geochemistryand surface expressionsof
mineralisedhorisonse
OP011e/10
-10-
Although there at the time of writing
is no elsar out pic ture of the geological
situation
at Andreasberg,
one may
come out of the mapping by Ryan.
Nowever, there still
remaina a problem of the quantity
of nickel,
and copper in
surface
mineralisation.
It may be of interest
to see what
the mise-i-la-masee
method would turn up with respect
to
ore in the Andreauberg
It seimma though that
this area also wants investigation
via a reliable
geophysical
møthod whose results
give the least
amount of ambiguity.
In
the event that this is unobtainable,
thon, as suggested
for
the Stang area, a series
of trenches
would appear to be the
only way to solve thøss quostions
short of drilling.
As, at
Stang, trenching
of this kind would facilitate
mapping of a
cross-sectiona1
nature,
and sampling of any •ncountered
mineralised
horisons.
The Jørstad
mise-i-la-masse
has shown that there oxiato
120,000 m2 surfacs
area of conduotor present.
Drilling
has
shown that th•re exista
.3% Ni, with good Nits ratioes.
There remains a question
of whether thøre exists
a massive
sulfide
sone.
To date the geological
situation
appears to
be mors complim than shown by Vokes-Vrålstad.
Perhaps these
complexities
will be enlightened
by Ryan.
Nowilver, in the
event thøy are
not,
then it is doubtful
that trenching,
als previously
mentioned,
would prove as useful.
Rather,
it
is felt,
what is needed is anothør geophysical
survey that
will
give bettør
definition
of thek anomalies,
and pinpoint
where any massive horison
may exist,
or define
aonøs where disseminatid
sulfidso
may exist
to the extent of potential
area
for an open cast mine.

Anomaly area 11 - the Rywil anomaly.
Aa thia anomaly has been

of the grade of nickel

As the ground geophysics
gave
a good indication
of the surfaa

it would bs of interest
to know what the down dip extension
