6.1 42B42BTopography, Elevation and Vegetation
The Berlin Project area lies on the eastern flank of the Cordillera Central at approximately
5° 31’ North and 75° West (Figure 5.1_1). The Berlin area is characterised by steep hills
separated by perennial streams at an altitude of 400-1,500 metres above mean sea level
(Figure 5.1_2). The Project lies within the catchment basin of the Rio Manso, which flows
eastward into the Rio Negro and then into the Rio Magdalena which flows northwards
between the Cordillera Central and Cordillera Occidental, discharging into the Caribbean Sea.

6.2 43B43BAccess and Infrastructure
The Berlin Project area is located in Caldas province of Colombia some 80km northeast of the
provincial capital, Manizales. It lies approximately 150km northeast of the national capital,
Bogota, and 100km southeast of the city of Medellin which also has an international airport.
Road access is good with the project area lying 59km from the paved Medellin - Bogota
highway. A secondary paved road leads 50km west from the Bogota-Medellin to the village of
Norcasia. The road continues, unpaved, 9km beyond to Berlin village. Agriculture is the
principal economic activity in the area.
The Magdalena River is navigable by barge from the town of Puerto Boyoca, some 65km
northeast of the project area to the port of Barranquilla on the Caribbean coast.
A railway line leads from the town of El Dorado on the Rio Magdalena to the port town of
Santa Marta on the Caribbean coast. Although the railway line is not currently in use, the
government has flagged it as a priority infrastructure project for completion by about 2015.
The 395MW La Miel hydroelectric dam is located approximately 12km from the central part of
the project area (Figure 5.2_1).

7 5B5BHISTORY
7.1 45B45BPrior Ownership of the Berlin Property
Minatome, a French exploration company, which has now been incorporated into AREVA,
undertook the most detailed exploration of the Berlin Project between 1979 and 1981. Its
work involved basic geological investigation followed by the core drilling, initial metallurgical
testwork and estimation of a uranium resource (not NI 43-101 compliant). Minatome is
reported to have withdrawn from the Berlin area when the company was nationalised by the
French government in 1981, which coincided with a slump in uranium prices.
After Minatome’s withdrawal from the project, the concessions reverted to the State. The
United Nations Development Program (UNDP) reviewed the technical work undertaken on the
project in 1982 and focused on the potential to recover uranium, molybdenum, vanadium and
phosphate from the Berlin area. The UNDP suggested that Dense Media Separation may
play a part in recovery of the various commodities.
Energentia Ltd, formerly KPS Ventures Ltd., applied for exploration concessions directly from
the State and also entered into an agreement with AngloGold Ashanti to acquire properties in
the Berlin Project area in 2007. Specifically, Energentia entered into an agreement with a
wholly owned subsidiary of AngloGold Ashanti, Sociedad Kedahda SA. Due to the slow
nature of related legal procedures, one of these property transfers is still in process and
completion is pending as described in Section 4 above. Subsequently, Mega Uranium Ltd
purchased Energentia Ltd on 1st May, 2008.
U3O8 Corp. closed the acquisition of Mega’s South American assets, including the Berlin Project,
on May 7th 2010. On 26th November 2010 Energentia Ltd name was changed to Gaia Energy
Investments Ltd and the Colombian branch name to Gaia Energy (Colombia) Ltd.
7.2 46B46BPrior Exploration
Phosphate was identified in the lower parts of the Cretaceous sedimentary sequence in the
Berlin area in 1968 (SRK, 2006). Uranium was identified in the phosphatic black shales in a
regional radiometric prospecting program undertaken by the Colombian Instituto de Asuntos
Nucleares (IAN) between 1977 and 1983. Minatome obtained permission from IAN to explore
the Berlin Project area for uranium in 1979. Field-based exploration carried out by Minatome
identified the black shale near the base of the Cretaceous sequence in the Berlin area as having
significant uranium grades. Rock-chip sampling resulted in the identification of highly
anomalous uranium values over the entire strike length of the synform in the Cretaceous
sequence in the Berlin area (Figures 6.2_1 and 6.2_2).
Minatome’s assay results from surface rock-chip sampling were substantiated by independent
sampling undertaken by Naranjo (1983), at the Universidad National in Bogota, who reported
mapping the uraniferous black shale over a strike length of approximately 3,000m in the
southern part of the synform in the Cretaceous sequence. Analyses from seven channel rock
chip samples and one point sample (Sample 6) were reported as shown in Table 6.2_1.

Minatome’s exploration concentrated on the southern 5km of the 10.5km long syncline where
access is easier and where outcrop of the sedimentary sequence is generally better in
comparison to the north. The apparent consistency of uranium grades along strike led
Minatome to excavate 20 trenches and 3 adits, the latter with the objective of confirming
mineralisation in fresh exposures beneath the saprolite. The location of the adits is shown in
Figure 6.2_3 and the assay results reported by Minatome are shown in Table 6.2_3.

Summary Assay Results of Channel Samples taken through the Uraniferous Unit in the Three Adits excavated by Minatome and whose Locations are shown in Figure 6.2_3
Minatome then drilled 11 widely-spaced drillholes for a total of 2,136m in 1980. Although six
of these drillholes are reported to have reached the target depth, nine are reported to have
intersected anomalous uranium values. IAN is reported to have drilled six drillholes in the
Berlin Project area in 1982 and 1983 and three of these holes are reported to have reached
the target horizon and to have intersected grades similar to those reported by Minatome over
similar true widths (SRK, 2006; Figure 6.2_4).

7.3 47B47BHistoric Resource Estimates
7.3.1 97B97BHistoric Resource Estimate
Minatome undertook a provisional, non CIM-compliant, grade estimate, using polygonal
methods based on assays of mineralised intervals of the drillholes whose collar positions are
shown in Figure 6.2_4 and rock-chip channel samples from the adits (Table 6.2_2) in 1981. The
historic estimate by Minatome, which covered the southern 4.5km of the 10.5km-long
mineralised trend in the Berlin area, was 12.9 million tonnes at a grade of 0.13% U3O8 for a total
of approximately 38 million pounds of contained U3O8 (Castaño, 1981). Minatome’s estimate
was not done in accordance with National Instrument 43-101 and therefore should not be
construed as a Resource or an indication of the Resource endowment of the project. The
estimate has been included only for historical context of the project.
7.4 48B48BMetallurgical Testwork
Minatome (Nancy, France) conducted various metallurgical tests on the black shales from the
Berlin Project in 1979 (Roussemet & Houot, 1979). Simple acid leaching resulted in a 75%
recovery of uranium, but with the consumption of 130kg of acid per tonne of uraniferous shale.
Provisional metallurgical testwork on a 35kg rock-chip sample from the adits showed the
following distribution of uranium (Roussemet & Houot, 1979):
5-10% of the uranium occurs on the surface of coarse fragments and is liberated during
crushing of the host-rock
55-60% of the uranium is associated with phosphate in the 40-200 micron (“µm”) fraction.
Testwork shows that the phosphate is amenable to flotation; and
Approximately 30% of the contained uranium occurs with the fine fraction, suspected to
be adsorbed onto illite and other clays, and was liberated on ultrafine grinding to a
nominal grain size of eight microns.
The conclusion from Minatome’s metallurgical testwork was that uranium recovery was
approximately 85% using a combination of flotation and ultrafine grinding of the fine fraction
(Roussemet & Houot, 1979). This work did not include an estimate of cost of processing.

Basement in the Berlin area is composed of greenschist to lower amphibolite grade pelitic and
graphite-bearing schists that are correlated with the Cajamarca – Valdivia terrane (CA-VA).
Elsewhere the CA-VA contains rocks of ophiolitic origin such as olivine gabbro, pyroxenite,
chromitite and serpentenite. Geochemical signatures suggest that these intrusive rocks are of
intraoceanic arc and continental margin affinity. They form part of a parautochthonous
sequence that was accreted onto the Chicamocha terrane along the Palestina fault during the
Ordovician to Silurian (Figures 7.1_1 and 7.1_2). Further south, the CA-VA was accreted
directly on to the Guyana Shield (Cediel et al. 2003).
The sedimentary sequence that contains the mineralisation at Berlin is lower Cretaceous in
age and is part of an extensive marine basin, the Magdelena Basin that was formed as a
thermal sag phase over active rifting involving extensive half-grabens of Jurassic to lower
Cretaceous age. Inversion of the extensional basin started in the Paleogene and accelerated
in the Late Miocene – Pliocene. This basin inversion resulted in the formation of the
Cordillera Oriental (Eastern Cordillera) in Colombia (Figure 7.1_2).
The Berlin Project lies on the eastern flank of the Cordillera Central where remnants of the
Cretaceous marine sequence overlie schists of the CA-VA (Figure 7.1_1).
Several batholiths occur in the vicinity of the Berlin Project (Figure 7.1_3). The Sansón
Batholith, located some 20km west of the project area, is a metaluminous I-type calc-alkaline
body of Triassic to Jurassic age that intruded the CA-VA. The Antioquia Batholith lies about the
same distance to the north of the project area and is middle to late Cretaceous in age with age
dates of 90-58Ma having been obtained (Cediel et al., 2003). It has a similar metaluminous, I-
type, calc-alkaline composition to the Sansón Batholith. The Samaná Batholith is located
immediately to the west of the Cretaceous sedimentary sequence at Berlin, and some igneous
phases intrude the sedimentary sequence that hosts the mineralisation.
Folding of the lower Cretaceous sedimentary sequence at Berlin is assumed to have taken
place in response to inversion of the basin which started in the Paleogene. The age of the
associated axial planar cleavage to folds in the Berlin area provides a time-line against which
the relative age of mineralisation can be established.
8.1.1 98B98BLithology and Stratigraphy
Basement
The Paleozoic basement in the Berlin Project area consists of metamorphic rocks – mainly
greenschists, graphitic schists and quartzites. Nuñez et al. (1979) maintain that the Paleozoic
sequence in the Berlin area may correlate with the Cajamarca Group of Nelson (1957), the
Ayura-Montebello Group of or the Valdivia Group. More recently the sequence has been
referred to as the Metamorphic Rocks of the Central Range (Feininger et al., 1972),
Cajamarca Terrain (Etayo-Serna et al., 1986), Tahamí Terrain (Toussaint and Restrepo,
1988) and the Cajamarca Complex (Maya and González, 1995). Here it is referred to as the
Cajamarca-Valdivia terrane, following the usage by Cediel et al. (2003).

14.5.4 120B120BFlotation Tests
Berlin Composite Sample
Six scoping flotation tests were carried out on the “Berlin Comp” composite sample as follows:
Five of the tests focused on removing apatite from the mineralised material:
The two initial tests (F1 and F2) were conducted on whole ore and examined pre-
flotation of fine, organic carbon ahead of an apatite flotation circuit;
The following three tests were completed on stage-ground and deslimed feed that
went to apatite flotation (Tests SB1-SB3).
The sixth test (Test SB4) was undertaken on stage-ground and deslimed feed and
attempted to float uranium minerals.
Results of the flotation tests can be summarised as follows:
F1 - Desliming in F1 was unsuccessful because of the fineness of the grind (80% passing
50µm). Pre-flotation to remove the graphitic carbon was not successful, recovering ~10%
of the uranium in ~7% of the mass, but it was clear that carbon was still floating in the
phosphate roughing stages, suggesting that higher frother dosages or a frother blend could
improve the recovery of graphitic carbon and U3O8 to the pre-float concentrate.
F2 – Pre-flotation of the graphite yielded results similar to those of F1 with 9% of the
uranium in ~7% of the mass.
Tests SB1 to SB4 used stage-grinding to avoid overproduction of fines. Desliming of the
stage-ground ore resulted in recovery of 27%-30% of the U3O8 in ~14% of the mass.
Attempts to selectively recover apatite in tests SB1 to SB3 were unsuccessful due to the
large amount of graphitic carbon in the ore and possibly due to poor liberation. The same
conclusion can be made for test SB4, where it was attempted to selectively float the
uranium minerals.
DDB10-15 Composite Sample
Given that the graphite in the prior tests appeared to inhibit flotation, all of the subsequent
tests on composite DDB10-15 included a carbon pre-flotation circuit. This composite sample
also has a higher carbonate content than Berlin Comp on which the prior flotation tests were
done. Six tests were done on the DDB10-15 composite sample as follows (Table 13.5.4_1):
DDB-F1 & DDB-F2: Tests DDB-F1 and DDB-F2 were designed to investigate the effect
of grind size on apatite flotation. The tests included a pre-float carbon step, followed by
apatite flotation. Test DDB-F1 was done at a relatively coarse grain size of 104µm and
DDB-F2 on a finer grain size of 58µm.
DDB-F3 & DDB-F4: In these tests, Step 1 was carbon pre-leach, Step 2 was a sulphide
flotation stage using PAX (a sulphide collector), Step 3 was a dilute hydrochloric acid
leach of the sulphide rougher tails prior to apatite flotation in order to clean the calcite
surfaces in an attempt to reduce accidental activation.

Berlin Project, Colombia – MINEWPER00790AC Page: 106 National Instrument NI 43-101 Report – 2 March 2012
DDB-F5 & DDB-F6: Step 1: A charge of composite DDB10-15 was ground to a K80 of
~60µm. Step 2 involved the use of acetic acid to dissolve as much calcite as possible. The
sample was leached with 220kg/t acetic acid for two hours and filtered. Step 3 was carbon
flotation and Step 4 was apatite flotation in the case of DDB-F5 and calcite flotation in the
case of DDB-F6.
Results:
DDB-F1 and DDB-F2 results showed that carbon recovery in the pre-flotation step, which
yielded 16% mass recovery, was better at the finer grains size; 64% at 58µm and 51% at
104µm. Selectivity between apatite and calcite was poor with 13% of the calcite and 15%
of the apatite reporting to the carbon concentrate (both tests) and 30%-31% of the uranium.
Leach tests were conducted on the DDB-F1 and DDB-F2 carbon pre-float material as well
as on the apatite rougher concentrates and results are as follows:
DDB-F1 Prefloat leach (Leach Test 68) – from the 31% of the uranium that reported to
the carbon pre-float concentrate (16% of the sample mass), uranium extraction was
91% with a sulphuric acid consumption of approximately 467kg/tonne of feed or
73kg/tonne of ore (Table 13.5.4_2).
DDB-F2 Prefloat leach (Leach Test 69) – 30% of the uranium reported to the carbon
pre-float concentrate (16% of the sample mass), from which uranium recovery peaked
at 85% at 48 hours but dropped to 77% at 72 hours, with an acid consumption of
605kg/tonne of feed or approximately 99kg/tonne of ore (Table 13.5.4_2).
An acid leach test (Test 64) was done on the apatite concentrate from DDB-F1 that
contained about 43% of the sample mass and 52% of the uranium. Uranium
extraction was 97% and vanadium recovery was 92% with acid consumption of
702kg/tonne of feed or approximately 304kg/tonne of ore (Table 13.5.4_2).
An acid leach test (Test 66) was done on the apatite concentrate from DDB-F2 that
contained about 51% of the sample mass and 55% of the uranium. Uranium
extraction was 96% and vanadium recovery was 90% with acid consumption of
725kg/tonne of feed or approximately 370kg/tonne of ore (Table 13.5.4_2).
Leach extraction kinetics in the above tests were rapid and leach times of between 24
and 48 hours would possibly be optimal (Figure 13.5.4_1).
DDB-F3 & DDB-F4 results showed that 49%-52% of the sulphides were recovered in the
carbon pre-float and together, the carbon pre-float and sulphide circuit recovered 87-88%
of the organic carbon with 70%-71% of the uranium, 55%-57% of the phosphate and 48%-
59% of the calcite in 47% of the mass.
DDB-F5 & DDB-F6 results show that the acetic acid leach dissolved 26%-28% of the
calcite with only 3%-4% of the uranium. In the pre-float rougher step, 77%-82% of the total
organic carbon was recovered with 49%- 56% of the uranium, 39%-47% of the calcite and
24%-26% of the apatite in 26%-35% of the sample mass. Addition of a cleaning stage
reduced the mass of the carbon concentrate to 13% of the sample (DDB-F5) or 18.1%
(DDB-F6) containing 40% of the uranium (both tests), 29% (Test DDB-F5) to 32% (Test
DDB-F6) of the calcite and 25% (both tests) of the apatite.

Coffey Mining is unaware of any mining, metallurgical, infrastructure or other relevant factors
which may materially affect the resource. The availability of suitable water and power supplies
may be key factors in any future mining studies. Security factors may influence future operational
decisions, however the author understands that regionally the security situation is improving.
15.9 84B84BConclusions
The overall geometry and trend of the mineralisation is well defined but further infill
drilling is required to adequately define the areas of complex folding and structure.
Further investigations are required to determine if faulting is affecting the mineralisation,
particularly for portions considered suitable for underground mining.
Further density data is required within the mineralised zone.

21 19B19BENVIRONMENTAL STUDIES, PERMITTING AND SOCIAL OR COMMUNITY IMPACT
As the Berlin Project is currently in the exploration stage, there have been no specific
requirements for environmental studies and social or community-related plans; however all
exploration work must be done in accordance with environmental guidelines (see Environmental
License under Section 4.1.6). Nonetheless, U3O8 Corp. has been pro-active in undertaking
social and environmental initiatives. These initiatives include providing local employment,
education campaigns and information workshops to discuss exploration plans with local leaders,
landowners and residents, establishing agricultural and small-scale fish producing projects as
alternate sources of food and income for local communities, supporting local school and
community activities as well as minimizing environmental impact by limiting the number of roads
through the use of a cable system to transport equipment and personnel around the project,
practicing health and safety measures such as protective gear and radiation monitoring for all
employees. Biodegradable lubricants and additives were used in the drilling. Drill water passes
through settling tanks prior to being re-used or discharged.
Nurseries have been established for the propagation of indigenous flora that is used in the
reclamation of drill platforms and other areas that require revegetation, such as the drainage
from which the Berlin village draws its potable water.

26 24B24BINTERPRETATION AND CONCLUSIONS
The Berlin Project comprises stratabound uranium and associated mineralisation at the contact
between a sandstone unit and overlying black, carbonaceous mudstone unit of a Lower
Cretaceous sequence. Mineralisation is predominantly contained within a phosphorous-rich
limestone layer within a north-north-east to north trending syncline. Typically, little significant
mineralisation occurs in the surrounding sediments. The mineralised layer ranges between
0.6m and 7m thick and averages 3m.
The uranium mineralisation occurs as secondary minerals from acidic, hydrocarbon-bearing fluid
dissolving rock and feldspar grains creating secondary permeability in the clastic carbonate
host-rocks, while simultaneously precipitating hydrocarbon and phosphate thereby roughly
maintaining the volume of the original rock.
The overall mineralisation geometry has been identified through diamond drilling and surface
trenching but still requires further delineation especially in areas of complex folding and to
determine if faulting is affecting the mineralisation zone.
U3O8 Corp. has completed a successful exploration program that has delineated a maiden
Resource for the project area.
A maiden Resource has been calculated for the Berlin Project (using a U3O8 cutoff of
400ppm U3O8.) of 8.1Mt at 0.11% U3O8 of Inferred material and 0.6Mt @ 0.11% U3O8 of
Indicated material. The success of the project will also depend, in part, on the local security
situation of the region.
Coffey has reviewed the drilling and QAQC data and considers it to be of a high standard for
use in the resource estimate.
Metallurgical testwork has investigated a number of means of extracting uranium, phosphate
and associated metals of potential economic interest. Two principal process routes have
potential to be applied at Berlin. The first, which has obtained outstanding recoveries for a
wide range of elements of potential economic interest, including uranium, at Berlin, includes
ferric leach of milled ore followed by a dilute acid leach. The second method that shows
promise for application at Berlin uses a pre-flotation step to generate an organic carbon – rich
concentrate that contains the majority of the uranium. An acid leach on the carbon-rich
concentrate appears to be effective in recovering uranium. Additional flotation tests are
underway to optimise the pre-flotation step and to define a flotation process for the resulting
carbon-poor material that will separate calcite and apatite so that apatite-rich material can be
subjected to leaching for metal recovery and/or the production of a phosphate product.

27 25B25BRECOMMENDATIONS
The following recommendations are made to advance the Berlin Project:
Additional drilling information is required to adequately define the areas of complex folding
and structure; determine if faulting is affecting the mineralisation, particularly for portions
considered suitable for underground mining; determine the northern extent of the
mineralisation. Further work is required to appropriately drill these holes, and any future
drilling programs will likely be guided by corporate objectives for the project. Accordingly,
the budget given below reflects a nominal program of 15 to 20 drillholes.
Further bulk density data is required to better quantify the density characteristics from
within the mineralised zone.
While chemical assaying is the preferred method for the Berlin Project, Coffey suggests
further analysis of radiometric eU3O8 data is required to improve the understanding of the
radiometric disequilibrium. A greater number of intervals with both chemical assays and
radiometric eU3O8 data are required to achieve this.
U3O8 Corp. has used good high grade standard reference materials, but Coffey
recommends using lower grade uranium standards of between 500ppm and 1,200ppm U3O8
to assess the precision of the lower grade material as well.
Further work is required to understand and model the depth of the weathering profile, and
assess the metallurgical properties of the weathered material.
Continue with testwork designed to establish optimal conditions for ferric iron leach of
whole ore. This work should focus on defining the effect of lower ferric iron concentrations
in solution as well as higher pulp densities as a means of reducing reagent consumption.
Additional flotation testwork is required to build on the success of certain aspects of
flotation, including the generation of cleaner sulphide and carbon pre-concentrates.
Work should continue on the separation of calcite and apatite through flotation in order to
provide a means of further reducing acid and/or ferric iron consumption.
A breakdown of projected costs to achieve the above recommendations is summarised in
Table 26_1.
