El Torno contains a large gold-rich quartz vein system that extends north-south for 14 km and is up to 20 metres wide. The central parts of the system have been worked since the Incas, resulting in about 1 km of underground galleries that are now flooded. The vein system was investigated by Puma Minerals in 1997 who carried out over 2,100 m of drilling. They were followed in 1999 by Peñoles (discoverer of the world’s largest silver mine and Mexico’s largest and richest gold mines) who undertook trenching, grab sampling, and geological surveying as well as a geophysical IP survey. The drilling showed that gold is concentrated in a 2 metre-wide zone on the western side of the main vein. Puma estimated that a 1.3 km length of the vein could have the potential for over 500,000 ounces of gold to a depth of 100 metres or 2 million ounces to a depth of 400 metres at an assumed grade of 10 g/t gold (not NI-43-101 compliant)

2. The El Torno Project
The El Torno Project, in the extreme north of Argentina, is an area of 78 km2 that
contains a very large gold-bearing quartz vein system that extends intermittently north-
south for 14 km with veins up to 20 metres wide.
The central parts of the system have been worked since the Incas, resulting in about 1
km of underground galleries, and more recent drilling has shown that gold is
concentrated in a 2 m wide zone on the western side of the main vein. Previous workers
estimated that a 1.3 km length of the vein could have the potential for over 500,000
ounces of gold to a depth of 100 metres or 2 million ounces to a depth of 400 metres at
an assumed grade of 10 g/t gold (non-NI 43-101 compliant).
Soltera has carried out two stream sediment geochemical sampling programmes and a
detailed structural survey. The results show that:
• The main vein system appears mineralized along its full length of 14 kilometres.
• The vein system is folded into an anticlinal form and the tested mineralization in
the west wing could extend across into the east wing which is totally untested.
• There are broad and strong stream sediment geochemical gold anomalies over
wide areas of the country rocks up to 2 km from the main vein that are centered
on suites of small veins and stockworks that could be major open-pit targets.
• The exploration area has been reduced effectively from 80 km2 to 10 km2 and
within this precisely defined area there is potential for several million ounces of
both underground and open-pit gold.
The next step is to carry out a two-pronged exploration programme on both the geo-
chemical anomalies and the main vein system. Mapping, surface sampling and small,
specifically targeted, geophysical programmes will be used to define drill targets.
Soltera is currently in the process of raising funding to carry out these programmes.
Introduction
The El Torno Gold Project is located in the province of Jujuy, in the Andean Cordillera of
northwest Argentina near the border with Bolivia (Figure 1). It covers an area of
approximately 78 km2 of grassland at a height of 4,000 metres above sea level.
The climate is semi-arid, with temperatures ranging from -5oC on winter nights to 25oC
on summer days. There is only rain, no snow, in winter, but the cold wet conditions
make operating difficult during a three month period from late May to late August. The
light vegetation is mainly “alfa” type grass and a little bush.
The area is accessible by road all year round from the village of Santa Catalina located
20 km to the east. Santa Catalina is 335 km by road from the city of San Salvador de
Jujuy which has direct flights to Buenos Aires.

Geology
This region is dominated by mildly metamorphosed sandstones and shales of Ordovician
age (Acoite Formation, Figure 2) which were folded along north-south axial planes
during the Jurassic. The folds vary from open to near-isoclinal and the axes are
dislocated in places by cross-faults. The whole folded sequence is cut by a series of
long inverse faults that strike north-south, dip gently west and thrust to the east causing
repeated stacking and repetition of the sedimentary units.
In the El Torno area the sedimentary sequence consists of two main units; a lower one
of coarse sandstones, and an upper unit of interlayered finer-grained sandstones and
shales. The lower, coarse sandstone, unit is more permeable and rigid versus the less
permeable, more flexible upper layer. This is an important control on the mineralization,
as described below.

5. Mineralization
The belt of Acoite Formation sandstones and shales extends at least 200 km north-south
within northern Argentina and contains numerous deposits of vein gold, vein lead-zinc-
silver and a limited number of sedimentary style copper deposits. This mineralized belt
continues northward into Bolivia.
At El Torno, the sandstones and shales are cut by a set of very large gold-bearing quartz
veins that extend intermittently for at least 14 kilometres north-south. The veins vary in
thickness from a few centimetres to over 20 metres and are concentrated along the axis
of a major north-south fold. They appear to be interlayered with the sedimentary strata
and dip gently in the main. In places, they are dislocated by cross faults.
Gold mineralization, as shown by old workings and drilling in the central part of the vein
system, is concentrated in a 2 metre-wide zone on the western side of the main vein.
The gold is associated with pyrite, often limonitised, but the gold itself appears to be
mainly free. Assays of drill core suggest an average around 10 g/t gold for the portion
that was drilled with values up to 37 g/t gold.
The main vein system is accompanied in places by broad stockworks of small quartz and
pyrite veins that can extend up to 300 metres outwards from the main vein and in some
cases occur up to 2 kilometres away and appear unrelated to the main vein system. Old
records show values as high as 112 g/t gold from surface samples of these stockwork
systems.
The mineralized systems, both the main veins and the stockworks, were possibly
emplaced during the Jurassic folding when the sedimentary sequence was penetrated
by gold-bearing hydrothermal fluids. The fluids migrated relatively easily through the
relatively permeable sandstones of the lower Acoite Formation and became
concentrated in zones of high permeability of low pressure. They were stopped,
however, by the relatively impermeable pelitic layers of the upper Acoite Formation unit
and so became concentrated as veins and stockworks in the lower unit. We believe that
this has considerable implications for exploration.
Past Activity
El Torno has been a producing gold mine for centuries. It was originally worked by the
Incas, then the Spaniards, and this resulted in over 1,000 metres of underground
galleries. More modern exploration, including geophysics and drilling, has been carried
out since 1997 with an estimated expenditure around $1.35 million.
In 1997 Puma Minerals Corp. (“Puma”) carried out geological mapping and drilled
sixteen holes totaling 2,015 metres using reverse circulation air hammer to a maximum
depth of 180 metres (Figure 3). The drilling, over a 1 kilometre length of the vein, gave
impressive results. Gold values for the main vein were between 5 g/t and 37 g/t gold
and stockwork samples showed up to 23 g/t gold accompanied by silver in a 1:1 ratio
(Table 1). It is interesting to note that samples of country rock intersected by the drill
holes commonly show 1-2 g/t gold. The drill assay values could well be low, because
reverse circulation air blast percussion drilling can easily lose gold.

Table 1: El Torno Drill Holes (May 1997) Sectors with Gold Anomalous Values.
In 1999, Industrias Peñoles, SA de CV (“Peñoles”) undertook additional exploration
including trenching, grab sampling and geological surveying as well as a geophysical
Induced Polarization survey. The three IP geophysical profiles conducted by Peñoles
suggest the presence of a flanking structure adjacent to the main vein with moderate to
high chargeability that is located at depth between 50 and 125 metres. This structure
has never been tested. Based on Puma’s historical drilling, and their own work, Peñoles
estimated that a 1.3 kilometre length of the vein would have the potential for over
500,000 ounces of gold to a depth of 100 metres and that the same length to a depth of
8

9. 9

10. 400 metres could have the potential for over 2 million ounces of gold at an assumed
grade of 10 g/t gold (non-tNI 43-101 compliant).
A private individual recently mined parts of the upper 2 to 3 metres of the main vein and
an alluvial deposit nearby. Gold was recovered as particles and micro-nuggets,
confirming that at least part of the vein gold is free rather than locked in pyrite grains.
The exploitation consisted of washing and gravity concentration with a trommel and
sluice system and produced about 300 grams of gold per day.
The gravity concentration plant is still at the site and in good condition, and Soltera is
examining the feasibility of restarting production which, although small-scale, would fund
exploration on the main targets.
Exploration by Soltera
Soltera has concentrated to date on several stream sediment geochemical surveys and
a detailed structural survey. To date, the company has spent around $150,000 on this
exploration.
The first stream sediment geochemical survey, in late 2007, was strategic and covered
about 100 km2, including the whole El Torno property. It was intended as a first check to
establish whether only the central part of the vein system is gold-rich. The country is
rolling highland dissected by streams, so is well suited for this type of survey. A total of
596 samples were collected at selected locations on stream courses and the -80 mesh
fractions analysed in Canada.
The results show a series of distinct, very strong anomalies extending the full 14 km
length of the vein system, indicating that the gold mineralization is present along almost
its whole length (Figure 4). Even more interesting, was the presence of very strong and
broad gold anomalies up to 2 km away from the main system, which appear to be
centred over large areas of vein suites and stockworks in the country rocks. One of
these anomalies alone is 2 km long by 1.5 km wide. These broad but strong anomalies
gave the first indication that gold mineralization is far more extensive than previously
thought and, furthermore, they offer the distinct possibility that wide mineralized areas of
country rock may be previously unrecognised large-scale open-pit targets.
The structural study, completed in April 2008, focused on the main vein system,
concentrating on parts of the system exposed at the surface and in the old mine
workings. The results suggest that the quartz veins are broadly parallel to the
sedimentary layering, rather than steeply dipping as previously thought, and they thicken
in the anticlinal axis (Figs. 5 and 6). This is reminiscent of the Bendigo and Ballarat gold
fields in Australia and suggests the possibility of stacked mineralized vein systems along
the anticlinal axis at depth. Furthermore, the vein gold identified to date has all been on
the western side of the main vein in the western limb of the anticline, and there could
well be unidentified gold-quartz mineralization in the unexplored eastern limb.
The second stream sediment geochemical survey, in mid-2008, was tactical and focused
on the anomalies identified by the first survey. It consisted of just over 1,000 samples
covering an area of about 15 km2. The results were excellent and confirmed the
presence of a major gold anomalous zone about 5 km north-south and up to almost 2
10

11. 11

12. 12

13. km wide centered on the vein system but extending well beyond the vein into the country
rocks on either side (Figure 7). There is also a separate anomalous area of about one
square kilometer located about 1 km east of the main vein in the south.
The remote anomalies appear to be centered on large areas of vein suites and
stockworks that are concentrated the sandstone-rich lower unit of the sedimentary
sequence. This fits with the interpretation that the mineralizing hydrothermal fluids could
penetrate the lower, sandstone rich unit easily, but their movement was blocked by the
overlying pelitic upper unit. Erosion along the anticlinal axis has exposed the lower unit
and the outcrops coincide almost precisely with the geochemical gold anomaly that
extends 5 km north-south and 2 km east-west.
Potential
The vein system, apparently mineralized over most of its 14 km length, is a prime target
for future test work. If the vein gold extends into the eastern limb of the anticline or if
mineralization along the axis of the anticline is repeated at depth, then the potential
mineralized system could be much more extensive than previously thought. In that case,
the earlier (non NI-43-101 compliant) Peñoles estimate of more than 500,000 ounces of
gold to 100 metres depth could be increased by magnitudes. This is a target that
warrants diamond drilling.
Separately, the well-structured and strong geochemical gold anomalies throughout the
country rocks well beyond the vein system form precise and important exploration
targets for possible open-pit mineralization. In this respect, they differ from the vein
mineralization where the target is gold-rich quartz veins that would require underground
mining.
Both underground and open-pit targets are large-scale and are each large enough to
contain several million ounces of gold. The main vein system will require extensive
diamond drilling, but the open-pit targets are relatively easy to test by a combination of
surface sampling, percussion drilling and diamond drilling.
It is interesting to note that there are some similarities between El Torno and AngloGold
Ashanti Limited’s Cerro Vanguardia Mine in the south of Argentina. In particular, the El
Torno vein system with its attendant suites of small veins in the country rocks appears
similar, at least superficially, to Cerro Vanguardia where the gold mineralization occurs in
a series of narrow hydrothermal quartz veins that occupy specific structures. Total gold
production in 2007 was 220,000 ounces of gold at cash costs of $261 per ounce of gold.
This is a rich open-pit mine system with total resources of approximately 3.5 million
ounces at just over 3 grams of gold per tonne and reserves of 1.9 million ounces of gold
at a grade of 6.52 grams of gold per tonne. Soltera looks to the Cerro Vanguardia Mine
as a potential exploration and production model for El Torno.

15. Conclusions
The net result of Soltera’s exploration programme is:
• The main vein system appears mineralized along its full length of 14 kilometres.
• The vein system is folded into an anticlinal form and the tested mineralization in
the west wing could extend across into the east wing which is totally untested.
• There are broad and strong stream sediment geochemical gold anomalies over
wide areas of the country rocks up to 2 km from the main vein that are centered
on suites of small veins and stockworks that could be major open-pit targets.
• The exploration area has been reduced effectively from 80 km2 to 10 km2 and
within this precisely defined area there is potential for several million ounces of
both underground and open-pit gold.
• There are similarities between El Torno and AngloGold Ashanti’s Cerro
Vanguardia mine in the south of Argentina where gold is mined in relatively small
open-pits centered upon a series of narrow hydrothermal quartz veins that
occupy specific structures.
The next step is to carry out a two-pronged exploration programme on both the geo-
chemical anomalies and the main vein system. The geochemical anomalies will be
tested by a limited geophysical survey, surface sampling, trenching, and shallow drilling.
The vein system will be tested also by a geophysical programme, followed by mapping
of the old gold workings and a limited programme of diamond drilling.
Soltera is currently in the process of raising funding to carry out these programmes.
