AURELIAN INTERSECTS 158.40 METRES GRADING 25.21 G/T OF GOLD, 70.45 METRES GRADING 9.15 G/T OF GOLD AND 134.97 METRES GRADING 5.61 G/T OF GOLD IN INFILL DRILLING AT FDN
Aurelian Resources Inc. has received results from 10 additional drill holes from the buried epithermal gold-silver discovery at Fruta Del Norte (FDN) on its wholly owned Condor project in southeastern Ecuador. These include 158.40 metres grading 25.21 grams per tonne gold (Au) and 19.0 g/t silver (Ag) in infill hole CP-07-139 and 134.97 metres grading 5.61 g/t Au and 8.5 g/t Ag in drill hole CP-07-132, which has added significant mineralization to Section 9583400N. Also included was 70.45 metres grading 9.15 g/t Au and 26.0 g/t Ag in infill drill hole CP-07-134 on Section 9583500N. At the eastern edge of the deposit on Section 9582900N, drill hole CP-07-129 assayed 236.50 metres grading 2.81 g/t Au and 10.2 g/t Ag.
"With the current resource definition drilling program completed, our efforts to better define the northern and southern extents of FDN are now the priority for drilling at the deposit," says Patrick F.N. Anderson, Aurelian's president and chief executive officer. "A drill rig is currently being mobilized to the Papaya target, 700 metres north of FDN. This rig will drill a fence of holes across an area with anomalous copper-gold and gold-bearing float and outcrop. The Papaya target is interpreted to occur within the continuation of the Las Penas fault zone, the structure that hosts FDN. The NI 43-101-compliant mineral resource estimate is proceeding well, but will likely be delayed a number of weeks due to the late arrival of key assay data and additional work required to determine how best to incorporate some of the high-grade assays in the FDN dataset."
Aurelian also wishes to confirm that it has no asset-backed commercial paper.
A table containing more complete intercepts from the 10 additional drill holes is presented herein, while maps, cross-sections, photos, and full gold and silver assay data from this and previous press releases may be viewed at the company's website.
FDN results
Results are summarized in the tables herein. Intervals containing high-grade assays have also been recalculated using a top cut of 105 g/t gold.

CP-07-125 (azimuth 092/dip minus 64) was drilled on Section 9582700N to test the southeast continuation of the FDN system toward the Bonza-Las Penas epithermal deposit. The hole clipped the eastern edge of the FDN system before entering the fault zone. The mineralized interval assayed 57.10 metres of 0.90 g/t Au and 5.4 g/t Ag.
On Section 9582800N, two holes (CP-07-131 and CP-07-135) have been completed on the eastern edge of the system. Both holes intersected broad zones of epithermal stockwork veining, with hole CP-07-131 (azimuth 88/dip minus 63) assaying 302.54 metres of 1.96 g/t Au and 14.1 g/t Ag, which includes a higher-grade interval of 42.30 metres of 4.53 g/t Au and 11.1 g/t Ag. At depth, the hole intersected a further 74.76 metres assaying 2.16 g/t Au and 29.8 g/t Ag. Further east, CP-07-135 (azimuth 90/dip minus 56) returned intervals of 21.89 metres of 1.22 g/t Au and 5.8 g/t Ag and 74.20 metres of 1.24 g/t Au and 9.3 g/t Ag.
Two holes (CP-07-129 and CP-07-136) have also been completed in a similar eastern location on Section 9582900N. Both holes have again intersected a broad zone of epithermal stockwork veining, with an interval of 236.50 metres of 2.81 g/t Au and 10.2 g/t Ag, including 6.05 metres of 59.80 g/t Au and 40.3 g/t Ag from CP-07-129 (azimuth 81/dip minus 65) and 77.34 metres of 0.90 g/t Au and 8.9 g/t Ag from CP-07-136 (azimuth 85/dip minus 57) farther east.
On Section 9583000N, drill hole CP-07-138 (azimuth 90/dip minus 53) was drilled to close off the system to the east for the upcoming resource estimate. The hole intersected only weak epithermal mineralization and, consequently, did not contain significant intercepts.
CP-07-133 (azimuth 85/dip minus 62) was drilled at depth on Section 9583100N; the hole intersected epithermal stockwork mineralization assaying 33.00 metres of 0.71 g/t Au and 1.4 g/t Ag, followed by 9.00 metres of 1.33 g/t Au and 3.2 g/t Ag.
On Section 9583400N, drill hole CP-07-132 (azimuth 89/dip minus 63) was drilled to test the top eastern corner of the system. This drill hole intersected mineralization higher than expected, due to an internal fault that steps the mineralization down to the west through the central part of the deposit. For technical reasons, the hole prematurely stopped in mineralization returning an interval of 134.97 metres of 5.61 g/t Au and 8.5 g/t Ag, with the final 15.74 metres assaying 15.20 g/t Au and 14.7 g/t Ag. The hole was subsequently twinned with drill hole CP-07-137 (assays pending), which successfully passed through the entire mineralized zone.
Also on Section 9583400N, CP-07-139 (azimuth 98/dip minus 50) was designed to test the continuity of the high-grade mineralization on the eastern edge of the system. The hole drilled through the west fault and into intense epithermal mineralization at 301.80 metres, exiting the mineralization at 460.20 metres. Uncut, the interval assayed 158.40 metres of 25.21 g/t Au and 19.0 g/t Ag. The hole included zones of high-grade mineralization with significant visible gold, including 11.15 metres of 193.49 g/t Au and 81.2 g/t Ag, which in turn includes 0.85 metre of 2,090.00 g/t Au and 789.0 g/t Ag. This correlates with high-grade intercepts in previously released drill holes (CP-06-57 and CP-07-100), indicating that this is a significant zone of high-grade mineralization.
Further north, drill hole CP-07-134 (azimuth 76/dip minus 60) was angled onto Section 9583500N to fill in the deep part of the system. At 407 metres, the hole passed through the west fault and into intense epithermal mineralization, assaying 70.45 metres of 9.15 g/t Au and 26.0 g/t Ag.
Results from 84 diamond drill holes have been released for the FDN deposit to date. Further drill results will be released as analytical data are received, validated and compiled.
The FDN deposit is interpreted to be an intermediate sulphidation epithermal gold-silver system. The deposit is buried by dominantly postmineralization 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 stockwork veining and hydrothermal brecciation within intensely silicified andesitic volcanic rocks that underlie the basin.
Drilling at the FDN deposit has outlined a mineralized envelope that is traceable continuously for over 1,200 metres along strike, exceeds 100 metres in width through the central and southern portions, has a vertical extent of over 250 metres, and dips moderately westward through to vertical with an eastern contact that dips steeply to the east, south of Section 9583500N. Drill holes intersect this envelope at an angle and therefore drill hole intercept widths reported in this press release are not true widths.
Samples consist of half NQ-size, NTW-size and BTW-size diamond core that are split by diamond saw on site, prepared at the ALS Chemex laboratory in Quito and assayed by 50-gram fire assay with an AAS or gravimetric finish at the ALS Chemex laboratory in Lima. The quality assurance and 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 gold are also regularly run as additional QA/QC checks. The remaining half of the core is retained for verification and reference purposes.
