This document summarizes exploration work conducted on mining claims in Nevada, Chile. Multiple datasets were integrated to identify targets for further exploration, including ASTER imagery to map alteration minerals, magnetic data to identify potential intrusive bodies, induced polarization surveys to map subsurface features, and hyperspectral imagery to map silicification and identify alteration minerals. Drilling of priority targets identified sulfides and traces of gold. A circular feature with coincident alteration was identified as a potential mineralized porphyry system warranting additional geophysics. The document advocates integrating diverse datasets and developing spatial visualization tools to aid exploration.

Gold prospecting using Remote Sensing ‘A case study of Sudan’IJERD Editor
Gold has been extracted from northeast Africa for more than 5000 years, and this may be the first
place where the metal was extracted. The Arabian-Nubian Shield (ANS) is an exposure of Precambrian
crystalline rocks on the flanks of the Red Sea. The crystalline rocks are mostly Neoproterozoic in age. ANS
includes the nations of Israel, Jordan. Egypt, Saudi Arabia, Sudan, Eritrea, Ethiopia, Yemen, and Somalia.
Arabian Nubian Shield Consists of juvenile continental crest that formed between 900 550 Ma, when intra
oceanic arc welded together along ophiolite decorated arc. Primary Au mineralization probably developed in
association with the growth of intra oceanic arc and evolution of back arc. Multiple episodes of deformation
have obscured the primary metallogenic setting, but at least some of the deposits preserve evidence that they
originate as sea floor massive sulphide deposits.
The Red Sea Hills Region is a vast span of rugged, harsh and inhospitable sector of the Earth with
inimical moon-like terrain, nevertheless since ancient times it is famed to be an abode of gold and was a major
source of wealth for the Pharaohs of ancient Egypt. The Pharaohs old workings have been periodically
rediscovered through time. Recent endeavours by the Geological Research Authority of Sudan led to the
discovery of a score of occurrences with gold and massive sulphide mineralizations. In the nineties of the
previous century the Geological Research Authority of Sudan (GRAS) in cooperation with BRGM utilized
satellite data of Landsat TM using spectral ratio technique to map possible mineralized zones in the Red Sea
Hills of Sudan. The outcome of the study mapped a gossan type gold mineralization. Band ratio technique was
applied to Arbaat area and a signature of alteration zone was detected. The alteration zones are commonly
associated with mineralization. The alteration zones are commonly associated with mineralization. A filed check
confirmed the existence of stock work of gold bearing quartz in the alteration zone. Another type of gold
mineralization that was discovered using remote sensing is the gold associated with metachert in the Atmur
Desert.

1. Nevada, Chile
Multiple Dataset Integration Exercise
Presented at the Workshop on Remote Sensing – Geological
Society of Nevada Symposium 2010, Reno, NV

2. Introduction
• Drill, baby, drill – not only vote-gathering
ploy, but main mantra of junior exploration
companies
• Often require multiple datasets to reach
decision right there and then “what your
gut tells you to do”
• You can’t often explain to exploration
manager what exactly you are doing
• Reaching out towards super-spectrum!
3. Location Map
MARICUNGA TREND
•Nevada area is located with 14 major prospects including 3 operating mines on
Maricunga Trend, which is appx. 150 x 30 km
•Comprised of NNE trending chain of andesitic to dacitic volcanoes and hosts series
of epithermal high sulfidation and porphyry-style gold-silver-copper deposits.
4. Location Map
Later flows
Advanced argillic alteration zones occur in association with porphyry
stockwork systems which intrude Eocene-Oligocene andesitic and
dacitic volcanic rocks
Later flows and cover obscure alteration assemblages
5.
6. Overview, E
Exeter Caspiche discovery is being drilled, and Exeter keeps adding more
resource numbers almost on daily basis.
Distance is about 4km south of Nevada claims
7. ASTER FeO
Pervasive with alteration areas but also associated with later stage
volcanic cover (supergene / weathering phenomena)
8. ASTER Hi-S
More indicative of alteration is alunite-kaolinite mix, suggestive of
Maricunga-type advanced argillic alteration. Note pervasive alteration in
Exeter area, exposed and relatively free of later volcanic cover
9. ASTER Si
Beginning to cook with some real information– coarse resolution, but it tells
the story where the real action might be. Note silicification justtbeneath
basaltic flows at Nevada – large system covered?
10. Mag - ASTG
Analytic signal total gradient data reveals some potential targets of interest:
i.e. porphyry targets in alteration zones, but majority of signal dominated by
later stage flows
11. Induced Pol.
In order to “see” below, another attempt with IP/Res surveys 100 and 200m
spacing across main zones of interest
14. Moving on
In next sequence we will focus on hyperspectral data provided by SpecTIR
as a proof of concept.
15. Hyperspectral
2m ProSpecTIR data collected over the area in 2008. Information was
processed using broad-spectrum alteration minerals and then tightened up
accordingly – shown are SAM-generated classes of “tight” endmembers
16. HSI and Mag
Note alteration minerals in proximity to potential stocks identified on mag.
Particularly interesting is the central cluster.
17. HSI looking S
Note pervasive silicification and apparent erosional (?) alunite (thanks,
Dave Coulter), also note alteration window beneath basalts.
19. Drilling
• Decided to drill in NE segment in
vicinity of large possible intrusive
• Encountered sulfides and traces of
gold
• Additional work planned
•Gold values around 0.6 g/T
LHS: pyrite histogram, maximum = 20%
RHS: magnetic susceptibility, as measured on drill-core
NOTE: all drill-core was measured for magnetic susceptibility
Upper Middle Unit
Lower Middle Unit
Basal Unit
25. Moving on
Noted feature, circular shape with slight topographic relief noted in northern
quadrant of Nevada claims – no road to it at the time, but recently dozed
26. Bulls-Eye ?
Alteration (from HSI) suggests circular, almost bulls-eye pattern. Field visit
suggest for possibility of small intrusive porphyry (evidence seen in
drainage behind). Textbook mineralization and alteration system?
27. HSI+ASTER
Silicification partially supports idea of this being potentially mineralized
system, planning on covering area with additional geophysics (as it was
outside of original survey)
28.

30.
31. Superspectrum?
•What would be the way to integrate and display
information from disparate datasets?
•Google Earth’s mass-appeal. No one knew…
•Can we make “spectral libraries” of mineralization
guides?
•Spatial spectra rather than graph spectra?
•Layercake spectrum?
•Geophysics important element to be used with
remote sensing
