Aurelian Intersects 250 Metres Grading 35.18 g/t Gold and 264 Metres Grading 5.40 g/t Gold in Infill Drilling at FDN
3/27/2007
TORONTO, ONTARIO, Mar 27, 2007 (CCNMatthews via COMTEX News Network) --
Aurelian Resources Inc. (TSX:ARU) today announced results from four additional drill holes from the buried Fruta Del Norte ("FDN") epithermal gold-silver discovery on its wholly-owned Condor Project in south-eastern Ecuador. These include a 250 metre interval grading 35.18 g/t gold ("Au") and 27.1 g/t silver ("Ag") in drill hole CP-07-100 on line 3400N, and a 264 metre interval grading 5.40 g/t Au and 8.8 g/t Ag in drill hole CP-07-101 on line 3300N. These latest results demonstrate continued success from our infill drilling program in support of an inferred resource estimate over a portion of the deposit by mid-2007.

"The infill drilling program continues to deliver and confirm high grade over long intersections in the central part of the deposit. The program is exceeding our expectations by not only confirming the mineralization we have already drilled but by adding grade and width to the known deposit. Soon we will have enough data to perform an initial inferred resource estimate over approximately one kilometer of the FDN deposit, which remains open to the south and at depth," says Aurelian President & CEO Patrick F. N. Anderson. "The deposit is faulted off to the North and the West. Currently, we have a drill rig looking for the proposed western block extension and surface geological mapping efforts are focussed on finding the northern extension."
Results are summarized in the tables below. Intervals containing high grade assays have also been re-calculated using a top cut of 105g/t gold.

CP-07-100 (azimuth 089/dip -63) was drilled on line 9583400N, between holes CP-06-57 and CP-06-58. Both of these earlier holes returned long, high-grade intercepts of 189 metres at 24 g/t gold (PR June 6, 2006) and 255 metres at 12.55 g/t gold (PR June 21, 2006) respectively. CP-07-100 crossed the contact between the Suarez conglomerate and the Misahualli andesites at 214.70 metres down hole, and immediately intersected intense epithermal quartz-carbonate-sulphide stockwork veining and brecciation with abundant visible gold. Between 387.80 m and 423.26 m the hole intersected very intense veining with pervasive visible gold and assayed 35.46m @ 133.05 g/t Au and 104 g/t Ag, including 1.02m @ 2447.20 g/t Au and 1100.0 g/t Ag. The hole then passed into a weaker stockwork zone before intersecting the high grade Muchacho vein between 443 and 448 m assaying 5m @ 204.14 g/t Au. Low intensity stockwork mineralization continued to 464 m. The entire 250 m mineralised interval assays 35.18 g/t Au and 27.1 g/t Ag. Using a 105 g/t Au top cut the hole assays 250 m at 15.02 g/t Ag and 27.1 g/t Ag.
CP-07-101 (azimuth 87/dip -53) was drilled as an infill hole on line 3300N, crossing the trace of holes CP-06-51 and -56. The hole drilled through the base of the Suarez conglomerate at 283.46 m down hole and into intense quartz-carbonate-sulphide stockwork veining and brecciation in andesites. Mineralization continues to 518.00 m downhole, with the entire interval assaying 264.00 m @ 5.40 g/t Au and 8.82 g/t Ag. The interval includes a high grade zone of 50.36 m @ 14.77 g/t Au and 20.47 g/t Ag. The hole ended at a depth of 559.30 m.
CP-06-94 was drilled on line 2800N, up-dip from hole CP-06-90 (PR January 31, 2007). The Suarez formation conglomerate - andesite contact was intersected at 406.25 m down hole. The andesites contain both sporadic quartz-carbonate-sulphide stockwork and narrow sheeted banded epithermal veins. The mineralisation increases in strength down hole with the hole ending with 243.14 m @ 2.30 g/t Au and 20.6 g/t Ag. The intercept contains a number of high-grade zones with visible gold including 16.60 metres assaying 6.64 g/t Au and 52.0 g/t Ag, and 2.70 metres assaying 18.34 g/t Au and 80.6 g/t Ag. The results indicate that the strongest zone of epithermal mineralisation is swinging to the east at the southern end of the system. Additional drill holes have been planned to test this hypothesis.
Drill holes with assays pending or in progress include infill holes CP-07-102 on line 2900N, CP-07-103 on line 3100N, CP-07-105 and CP-07-106 on line 3200N, CP-07-109 on line 2800N, CP-07-110 on line 3700N, CP-07-111 on line 3700N and CP-07-112 on line 3500N. Drill hole CP-07-107 is a scissor hole that has been completed on line 3300N. Hole CP-07-108 has begun testing the western fault block on line 2600N.
Holes CP-07-98, 99 and 104 have been completed on sections 9582700N and 9582600N to test the southern continuation of FDN, although CP-06-98 failed to reach its target depth due to difficult ground conditions encountered while traversing a major fault.
South of FDN on section 9582000N, drill hole CP-07-97 intersected epithermal silicification and marcasite replacement of the Suarez conglomerates. However, no epithermal mineralization was intersected in the underlying andesites and the hole was not sampled.
Results from forty-six diamond drill holes have been released for the FDN prospect to date. Further drill results will be released as analytical data are received, validated and compiled.
The FDN target is interpreted to be an intermediate sulphidation epithermal gold-silver system. The deposit is buried by dominantly post-mineralization basin infill sediments (Suarez Formation) of Jurassic age within a pull-apart basin. The hydrothermal system is characterized by a combination of multiphase quartz-carbonate-sulphide stock work veining and hydrothermal brecciation within intensely silicified andesitic volcanic rocks that underlie the basin. In the southern part of FDN (south of 9583500N), the system is interpreted to dip moderately to steeply westward with a vertical structure bounding it to the east, and is cut by a steep east-dipping fault to the west. At the north end of the system (including and north of line 9583500N) the vein orientations and correlation of mineralization between drill holes indicates that the system is vertical.
Drilling at the FDN deposit has outlined a mineralized envelope that is traceable continuously for over 1100 metres along strike, exceeds 100 metres in width through the central portion, dips moderately westward through to vertical and has a vertical extent of over 250 metres. Drill holes intersect this envelope at an angle and therefore drill hole intercept widths reported in this press release are not true widths. The deposit remains open at depth and to the south. Both the infill and step out drilling programs continue to expand the size of the deposit. Independent experts Dr. Richard Sillitoe and B. Terrence Hennessey have confirmed that the orientation of Aurelian's drill holes is optimal for the FDN deposit.
Samples consist of half NQ, NTW and BTW-size diamond core that are split by diamond saw on site, prepared at the ALS Chemex laboratory in Quito, and assayed by 50g fire assay with an ICPAES, AAS or gravimetric finish at the ALS Chemex Lima Laboratory. The quality assurance-quality control (QA-QC) program of Aurelian includes the insertion of certified standards of known gold content every 20 samples, blanks at least every 20 samples and field or lab duplicates every 20 samples. Samples from significant drill intercepts are sent to two additional laboratories to verify gold and silver analyses. Metallic screen fire analyses for Au are also regularly run as additional QA-QC checks. The remaining half core is retained for verification and reference purposes.
