Exeter Discovers New High Grade Zone at Cerro Moro
Of six drill holes from the new zone with significant assays, the best result to date is from hole MD666, sited 20 metres ("m") (65.6 feet ("ft")) from the boundary of the Fomicruz joint venture property. In that hole a 2.43 m (7.97 ft) interval, from a down hole depth of 254.15 m (833.8 ft), assayed 13.3 grams/tonne ("g/t") (0.39 ounce / short ton ("oz/t")) gold and 699 g/t (20.27 oz/t) silver for a gold equivalent grade* of 25 g/t (0.73 oz/t). The interval included 0.40 m (1.31 ft) assaying 56.6 g/t (1.64 oz/t) gold and 2,473 g/t (71.72 oz/t) silver (gold equivalent 98 g/t (2.84 oz/t)). Significantly, the vein is situated in a hanging wall structure above the structural position that typically hosts the Escondida vein.
Results from 24 new diamond drill holes, 14 of which returned significant results, have been received from the new zone and the nearby Escondida Far West sector. As expected the results include bonanza grade intercepts such as MD617 and MD633.
Selected significant and bonanza drilling results using a 1 g/t gold equivalent* cut-off grade:

Exeter's Chairman, Yale Simpson stated "Our current drilling program is focussing on the high grade Escondida vein, and its immediate surrounds, particularly to the northwest. This program is proving to be successful, a rewarding outcome as this area is the site for initial mine planning.
"Drilling west of MD405, the most westerly of the Far West Sector drill holes, has intersected similar grades but over a greater width. In this area drilling will continue to focus on confirming, both at depth and laterally, the potential for addition high grade mineralization.
"Drilling and data interpretation is discovering veins within both footwall and hanging wall structures. One such vein, in historical drill hole MD260 at Escondida West, assayed 16.9 g/t gold over 2 m, some 60 m into the hanging wall. The structure has now been determined to have a co-incident geophysical anomaly suggesting untested strike and depth potential. In addition, two other historical drill holes, MD089 and MD106 at Escondida Central, intersected significant mineralization 10 m below the main structure (1.25 m at a grade of 67.4 g/t gold and 2,659 g/t silver in MD089, and 3.0m at a grade of 9.5 g/t gold and 1,1018 g/t silver in MD106).
"We now have 3 rigs on site, with 2 deployed on infill drilling to upgrade inferred resources to indicated resource status, and to test the strike extension of known mineralized structures. The 3rd rig is currently drilling for water as part of our engineering program. A 4th rig to assist with the infill drilling will be on site within the next week."
Of the 11 diamond drill holes with less significant results, holes MD612, MD614, MD615, MD621, MD629, MD632, MD637 AND MD638 returned narrow and/or low grade intersections. Drill holes MD623, MD626, and MD630 were poorly mineralized. The results from 36 holes at the Escondida Far West and Far East Sectors are awaited.
The locations of the 14 drill holes reported are represented on the following plans and long sections.

Quality Control and Assurance
Drill widths presented above are drill intersection widths and may not represent the true widths of mineralization.
Gold assay results presented above are preliminary and have been calculated using a 1.0 g/t gold equivalent cut-off grade, with no cutting of high grades. All diamond drill core samples are split on regular metre intervals or on geological contacts and represent sawn half HQ-size core. Samples were prepared at the Acme Analytical Laboratories ("AcmeLabs") preparation facility in Mendoza,
Check assaying of all samples assaying greater than 1.0 g/t gold is completed by Acme Labs. Samples returning greater than 10 g/t gold and/or greater than 100 g/t silver are assayed using gravimetric analyses. Standard and blank samples are used throughout the sample sequence as checks for the diamond drilling reported in this release. Standard, blank and duplicate samples are used throughout the sample sequence as checks for the RC percussion drilling.
Assaying by the screen fire assay method has been implemented in conjunction with standard 50 gram fire assaying, for diamond drill cores that contain visible gold. The procedure for screen fire assaying involves crushing and sieving of a nominal 1,000 gram sample to a particle size of 100 microns. All material which does not pass through the 100 micron sieve is then assayed. Two fire assays are undertaken on the undersize material as a check on homogeneity. The total gold content is then calculated.

(xx) Gold ("Au") equivalence for copper ("Cu") and silver ("Ag") was calculated by Exeter using assumed metal prices of US$800/ounce ("oz") for Au, US$12/oz for Ag and US$2/pound ("lb") for Cu. The formula to calculate Au equivalence for Cu was pounds of Cu multiplied by 2 and divided by 800; Au equivalence for Ag was calculated using the formula oz of Ag multiplied by 12 and divided by 800, and in both cases assumes 100% recovery. Reported grades and tonnes have been rounded (see news release NR 9-19 dated
(xxx) Inferred mineral resource estimate of 1,098,000 containing 371,000 ounces gold at a grade of 10.5 g/t and 19.2 million ounces silver at a grade of 545 g/t for 646,000 ounces gold equivalent at a grade of 18 g/t gold equivalent. Gold equivalent is calculated by dividing the silver assay result by 70, adding it to the gold value and assuming 100% metallurgical recovery (see news release NR 9-14 dated
