OROMINING DRILLS 167 METRES OF 2.0 G/T GOLD AT TAUNUS PROJECT, MEXICO
Oro Mining Ltd. has made significant progress on its Taunus projectwith the sonic drill program:
-- Discovery of shallow high grade gold mineralization in an arearecentlyaccessible due to the completed dewatering of the Taunus pit.- Sonic hole SN13 returned 166.6 metres of 2.0 g/t gold, including6.9g/t gold over 28.5 metres from a down hole depth of 36.7 to 65.2metres. This hole has discovered gold mineralization in anuntestedarea of the Taunus resource model, and is indicating a potentiallink between the Eldorado and HS zones (See Long Section).-- The average grade of the mineralized intervals in holes recentlydrilledby sonic methods in the Eldorado zone is 2.6 g/t gold (average widthof12.7 metres), compared to the average grade of nearby reversecirculation (RC) holes in the Eldorado zone of 1.1 g/t gold (averagewidth of 13.5 metres).-- A second sonic rig is being mobilized to complete the planned 5,000 mdrill program by the end of the second quarter. The sonic drillingtechnique is proving to be effective in the recovery of themineralizedbreccia material and definition of the Taunus deposit.-- Oro Mining has signed a surface agreement with the local communitywhichprovides provision whereby the Company can access and mine theTaunusdeposit. With this agreement completed, the Company is advancing theTaunus project with an aim of reaching a production decision.

Sonic Drill Results
Sonic holes SN10, SN11, SN12 and SN13 were drilling inside the existingpit. These are the first sonic holes drilled by Oro Mining in the coreof the Eldorado zone directly below the pit floor. Several holes alsotargeted additional gold-bearing breccia material in untested areasbetween the Eldorado and HS zones. Overall, as shown in the table below,the sonic results are returning a higher average gold grade as comparedto the average grade of the nearby RC or diamond holes.

Note: the reported intervals are a down-hole length, and may not represent a
true width. The table above compares the sonic assays to nearby RC or
diamond holes; note that the holes are not twins and the distance between
compared intercepts are in the range of 10 to 20 m.
Sonic holes SN11 and SN13 were drilled on the same section near thecenter of the pit.-- Sonic hole SN13 intersected 2.0 g/t gold over 166.6 metres. Thisholetargeted the shallow, Eldorado zone as well as the deeper 'gap zone'between the Eldorado and HS zones. The composite(1) is composed ofthreedistinct intervals:1. An upper interval of 0.5 g/t gold over 34.0 metres (from 0 to34.0mdown hole). This zone is interpreted to be the upper portion ofthemain Eldorado zone and has an interpreted true width ofapproximately 30 metres.2. A high grade interval of 8.0 g/t gold over 24.6 metres (from36.7 to61.3m down hole), interpreted to be the main Eldorado zone. Thisinterval appears to have a vertical component by changing in dipfrom approximately 45 degrees to approximately 60 degrees givingitan estimated true width of approximately 11 metres.3. A lower interval of 1.1 g/t gold over 105.8 metres (from 61.3 to167.1 m down hole). This portion of the mineralized interval isinterpreted to be higher angle or near vertical. The true widthofthis zone is estimated to be 20 to 30 metres.-- Sonic hole SN 11 is located 15 metres to the west of hole SN13 andintersected the main Eldorado zone of 3.7 g/t over 20.0 metres (from0to 20.0m down hole). The true width of this zone is estimated to beapproximately 11 metres.
Sonic holes SN10 and SN12 are located on the same section near the southend of the pit. Both holes intersected the Eldorado zone returning ahigher grade than previously reported by nearby RC holes.
Sonic holes SN7, SN8 and SN9 are located approximately 100 metresoutside of the Taunus pit and aimed at evaluating the gold grade of thenear surface Eldorado zone. These holes intersected higher grade goldthan nearby RC holes. Sonic hole SN8 intersected 3 gold bearing zones,the deeper zone of 2.4 g/t gold over 13.6 metres (from 125 to 138.6 mdown hole) is significant being located outside of the resource pitshell.
(1)Minimum composite length of 5 metres over 0.2 g/t Au, may include upto 3 metres less than 0.2 g/t Au
Exploration Plan
Total meterage completed to date this year is approximately 1,365 m in10 sonic holes. Technical delays and slower drilling have beenencountered with the sonic technique when drilling below 100 metredepths. It is important to acknowledge that the sonic drilling wasimplemented by Oro Mining as an innovative tool to complete the resourceexploration drilling to overcome the technical challenges experiencedat Taunus this past year, and will continue to require more time toestablish procedures and protocol, currently under review by anindependent qualified person.
The objectives of the sonic drill program are to increase the Taunusresource base by: 1) increasing the gold grade of the Eldorado and HSzones; and 2) drilling untested areas below the Eldorado zone targetingpotential high-grade gold feeders, as well as offsets and extensions tothe zones.
The Company is planning to complete another resource estimate for theTaunus gold deposit following the completion of the current sonic drillprogram.
Quality Control
Oro Mining maintains a strict quality control program. All samplesgenerated by Oro Mining were submitted directly to Inspectorate, an ISO9001-2008-certified assay laboratory, for preparation in Durango,Mexico, and analysis in Reno, Nev. All sonic drill samples submitted foranalysis were from splits of quarter-sawn frozen core. Analysis wasconducted on one-assay-tonne samples for gold, with a standard, blankand duplicate inserted for every 20 samples submitted. Analysis of goldwas by fire assay with AAS finish, and with gravimetric finish onsamples exceeding five g/t gold. Y.
