El Dorado Monserrat (EDM) comprises two licence blocks, termed Monserrat Block and Dorado Block, that include 11 Mines, 3 Discovery Manifestations and 2 claims covering some 3336.74 ha in total. The last area acquired is Anita, but there are several significant identified targets and not explored enough in the area.
Surface sampling, trenching and mapping discovered new veins with different trends and also improved the silver anomalism with a sample ranging 4917 g/t Ag, at the southern extension of the Vetas Principales, our most explored target.
The mineralisation in all known systems is open laterally and to depth, both within the exposed Chon Aike and Bajo Pobre host rocks and beneath recent basalt cover to the north as interpretation from the IP below it.
Several significant targets have been identified to date on EDM:
This is the most advanced target, extending in a north-south direction. The total length of vein exposures is approximately 6 km with an average thickness of 0.85 m, though there are large variations along strike from 0.25 m to 4 m. The veins occupy a north-striking, sinistral shear zone. Some of the best intercepts are:

El Dorado – Monserrat Potential: An in-house, non-compliant resource have been carried out by ACA Howe Int. Metal content was estimated up to 200,000 ozs Au and 6M ozs of Ag with the block model only extending to 150 m in depth in a small percentage of the veins in Vetas Principales. The system is open in depth with verified mineralization up to 260 vertical meters.
Mineralization occurs as segmented veins of multi-episodes quartz adularia-barite and sulphides. Strike length of 250m with width of up to 6m, averaging 1.50 m, with trends NNE-WNW and dips around 77° W - 90° characterize the quartz structures standing and occupy high relief associated with barite veins hosted in andesite rocks. Surface sampling returned gold values of up to 5.94 ppm Au, possible as electrum and less in auriferous pyrite, native, iron oxide, within quartz and saccharoidal minor replacement quartz. Silver values reported between 58.36 to 4917.58 ppm (average of 150 ppm) are possible related to native silver, electrum, as silver sulfides, associated with lead as andorita, less as argentiferous galena and silver sulfosalt. The mineralisation is open in all directions.
An almost completely buried vein system, evinced by a sinter and some minor outcrops, parallel to the Main Vein system that was traced for 900 m and remains open in all directions. The veining is hosted by silicified Chon Aike Formation rocks. Magnetics and IP show interesting features associated with geochemistry. Arsenic, antimony, barium and mercury values suggest that the system has been intersected at a high level in the epithermal system. Within the principal vein, significant intersections range from 0.97 g/t Au and 17.0 g/t Ag over a true width of 0.5 m to 2.35 g/t Au and 135.89 g/t Ag over 4.23 m.Gold values range up to 5.16 g/t over 1.17 m true width, and silver values up to 507.68 g/t over 1.6 m true width occur. In addition one hole drilled in 2011 returned an intersection of 0.5m, 3.78 g/t Au, 1377 g/t Ag from 179.5m.
Refers to the elongated 800 m width low-lying area between Vetas Principales to the east and Monserrat Oeste to the west, which exposes thin vein (up to 1 m) of quartz associates to old barite labors and jasper veining with NNW to NNE trending. Values of up to 73 g/t Ag and 1 /t Au were intercepted by holes at shallow levels along 100 m of extension, in an inferred NNW vein, including 0.3 m with 6.43 g/t Au and 513.36 g/t Ag.
Located 2 km east of the Main Vein system, a NNE trending zone of silicified ignimbrites and riodacitic tuff carries anastomosing quartz veinlets zone. A strong 1500 m long linear feature anomalous in arsenic, antimony and mercury, and subordinated silver and gold has been identified conjugate to the zone of silicification. Magnetometry supports its continuity in depth and to the south.
This area comprises a breccia body with narrow quartz veins carrying highly anomalous gold values contained within a zone of strongly iron-stained ignimbrite indicative of a proximal eruptive centre. Trenching returned anomalous gold values between 0.21 g/t Au and 30.00 g/t Au over widths ranging from 0.4 m to 13.8 m within a zone some 400 m long and 200 m wide; only incomplete results are available. The strongest gold values were associated with banded quartz veinlets and stockworks with lower, but anomalous values in the immediate wallrocks. Values intersected ranged from 1.96 g/t over an intersection width of 2 m to 0.21 g/t Au over 27.5 m, though intersection widths are likely to be some 50% greater than true width. The veinlets are subvertical and appear to correspond to mineralisation observed in trenches that ranged from 30 g/t Au over 0.4 m, to 1.21 g/t over 5.5 m true width. 28 wells were drilled with the next best results:

This prospect is in the southeastern part of the project area, where at least five south-southeasterly trending quartz vein zones are exposed along a strike length of at least 4 km within a zone about 2 km wide. Smaller veins occur between the major structures. The veins are hosted in ignimbrites and exhibit areas of focused hydrothermal alteration, and comprise structures up to 3 m wide containing chalcedonic and crystalline quartz, with well-developed colloform banding and carbonate replacement textures. Barite is also present, together with small amounts of pyrite, arsenopyrite, jarosite and sericite. Gold in channel samples varied between 0.01 and 0.58 g/t Au, while silver ranged from 1 to 17 g/t Ag. Zones of weak gold and silver anomalies tend to correlate with arsenic, antimony and mercury. Only a minor part of the system was drill tested. There is clear evidence of low sulphidation epithermal high level system mineralisation, and during the last works drilled five holes, with the next best results:

Comprises one licence that includes 1 Claim, covering some 2,300 ha in total. The El Dorado licence block is contiguous to the north and south with Anita.
The satellite image and the review on the ground show a system of structures trending northwest; it is clearly observed as a continuity of quartz veins that form part of El Dorado-Monserrat project. These structures, with a similar trend to Cerro Vanguardia’s veined system, located 20 km to the northeast, ending southward in a dome shaped that is observed with a strong alteration..
The known data of mineralization to the north indicate content of silver to 60 g/t and gold to 0.55 g/t; in the south already outside the property, two epithermal systems are manifested corresponding to two distinguishable events, constituting the continuity of Anita’s central sector southward a deposit with supported values of Au and Ag, with a maximum of 50 g/t gold in chalcedony veinlets hosted in a gap/breccia.
