Central Sonora State, 140 km north northeast of the city of Hermosillo and approximately 75 km southwest of the
Cananea porphyry copper mining district within the northern Mexico copper-molybdenum porphyry belt.
The mine is jointly owned with 50% Del Toro and 50% Yale Resources Ltd.
The Dos Naciones Property is an early stage exploration project with small scale historic production in numerous areas For pictures of the Dos Naciones property go here:
of skarn mineralization and silver-lead veins.
Copper-silver-zinc-gold skarns have been the focus of most exploration work to date however;
low sulphidation silver-lead veins have seen historic production in two locations.
In addition there is the potential for the property to host a porphyry.
The property is host to multiple skarn bodies that occur on the eastern and southern margins of a regional low magnetic anomaly that measures 2 km in diameter.
The anomaly coincides with an intrusive body with multiple strongly altered exposures that contain disseminated pyrite and local galena.
In addition there are several areas with historical mines that exploited high grade silver-lead veins.
The Josefina silver-lead target, located at the geographic centre of the property, consists of a series of sub-parallel veins ranging from 0.5 to 3.0 metres in width.
The veins have been traced over a strike length of at least 250 metres and the target remains open in all directions.
A total of six reconnaissance samples were taken with three of them being from vein, one from the dump (quoted above) and two from altered host rocks.
One of the outcrop samples returned 111.0 g/t silver over 1.9 metres.
However, a sample from the nearby mineralized dump returned 591 g/t silver and 12.60% lead, indicative of the material that was being mined.
The second new target area within the property is located two kilometres to the southwest. A set of silver-lead veins occur within intrusive host rocks over an area
that measures approximately 100 metres wide. There are numerous historic mines on at least two levels with a majority of these workings having collapsed over time.
Two samples were taken from the mineralized dumps at the mouths of these workings: one returned 256.0 g/t silver and 4.45 % lead while the second
returned 182.0 g/t silver and 3.29 % lead as well as 0.61 g/t gold. The eastern skarn forms a hill measuring 200 by 150 metres and is 50 metres high.
This hill has several workings around its edges as well as several small open cuts throughout.
Peñoles worked in the area in the 1990's performing mapping, geophysics and limited drilling.

This summary report describes the Dos Naciones Project property of Candev Resource Exploration Inc. (Candev),
north-central Sonora State, Mexico.
The writer has read National Instrument 43-101 and Form 43-101, and this report has been prepared in compliance with that instrument and form.
The writer fulfills the requirement to be a "qualified person" for the purposes of NI 43-101.
The Dos Naciones property is located approximately 140 km north northeast of the city of Hermosillo, in north-central Sonora, Mexico and
is approximately 75 km southwest of the important Cananea mining district.
The Dos Naciones Project property is located in north-central Sonora, Mexico approximately 60 km southeast of the town of Magdalena de Kino,
or 140 km north northeast of Hermosillo. The Dos Naciones Project property is accessible via a gravel road that leads to Rancho Los Janos;
this gravel road leads southward from the paved road between Magdalena de Kino and the village of Los Janos.
The turnoff southwards to Rancho Los Janos is about 10 km east of the village of Cucurpe. Fourwheel-
drive roads extend southwards beyond the ranch buildings and provide good access to all parts of the property. The Dos Naciones property is comprised of one mineral concession that covers approximately 2,391 hectares.
The Dos Naciones Project property is accessible via gravel roads that provide good access to all parts of the property.
About 3 hours is required to drive from Hermosillo to the property. The climate within the property area is semi-arid, typical of higher
elevations in the Sonoran desert; seasonal rains occur between April and July.
Northern Sonora is one of the most important mining areas in Mexico. A variety of different types of mineral deposits have been
mined within the region, including porphyry copper deposits at Cananea and Nacozari, Carlin-type gold deposits at Santa Gertrudis
and Amelia, and gold-silver veins at Klondike and Las Chispas (Heylmun, 1996).
Silverand lead-bearing quartz veins have been mined in at least two places on the Dos Naciones property,
at Josefina and at the Dos Naciones occurrence area. Historic workings on the Dos Naciones property
include pits and short adits excavated to extract copper from skarns.
The Dos Naciones Project property area is within the Cananea district of northern Sonora.
A wide variety of sedimentary, igneous and metamorphic rocks of various ages
occur in the region; the geologic history of this region is relatively complex.
The writer collected four geochemical rock samples from the Dos Naciones Project property area on March 9, 2009.
Three of these samples were collected from Dos Naciones occurrence area, and one from the Josefina area .
11.0 SAMPLE PREPARATION, ANALYSES AND SECURITY
The rock samples were bagged, and the bags were sealed by the writer. The samples
were then transported via truck from Dos Naciones property to Minera Alta Vista's
offices at Hermosillo, Sonora. The samples were delivered to ALS Chemex Laboratories
in Hermosillo on March 10, 2009 by the writer. The writer maintained custody of the
samples from the time the samples were collected until the samples were delivered to
ALS Chemex Laboratories facility at Hermosillo.
The rocks were analyzed for gold by geochemical fire assay, solvent extraction and
atomic adsorption spectrometry. A subsample of 30 gm was assayed. The rock sample
was also analyzed for silver, mercury, arsenic, antimony and 46 other elements by aqua
regia acid digestion ICPMS.
A certificate of analysis forms Appendix B. The rock sample descriptions are presented
in Appendix C.
