Gitennes Exploration (GIT-T) has moved two drill rigs on to the Alumbre gold pect at its Virgen property in north-central Peru in an effort to determine the extent of mineralization. Further stepout drilling on the Rio Suro Norte zone has been deferred until the potential of Alumbre has been fully tested.
Recent drilling on the northern extension of the Alumbre zone returned multiple intercepts of gold mineralization in hole V98-61. Drilled due west at an angle of minus 60, hole 61 intersected the following intercepts: 54 metres averaging 0.5 gram gold per tonne, starting at a downhole depth of 132 metres; 46.87 metres averaging 1.54 grams (including a 30-metre interval averaging 2.12 grams), starting at 223.13 metres; and 42.61 metres averaging 0.68 gram, starting at 300 metres.
The bulk of the mineralization is hosted in leached volcanic tuffs and breccias, where it is associated with alunite, sulphur and quartz. The volcanic unit is cut by abundant hydrothermal breccias, which Gitennes says are identical to those found at the Rio Suro zone, 650 metres to the west.
Mineralization and alteration in hole 61 is said to correlate with the original Alumbre discovery holes, V97-24 and V97-33, which lie to the south, 720 to 780 metres uphill. Hole 24 intersected a previously reported 33 metres averaging 11.37 grams, starting at a downhole depth of 153.1 metres, while hole 33 cut multiple intercepts: 14.9 metres averaging 18.33 grams, starting at a depth of 158.2 metres; 3.1 metres averaging 8.54 grams, starting at 186.8 metres; 26.8 metres averaging 3.46 grams, starting at 235 metres; and 21.3 metres averaging 1.64 grams, starting at 261.8 metres.
A total of 18 holes have tested the southern Alumbre area. Most were either lost before reaching the projected target, or, as was the case with holes V98-53 and V98-55, lost at the contact between mineralized and unmineralized rock.
Hole 53, a stepout east of hole 33, hit multiple intercepts: 7.25 metres averaging 0.56 gram gold, starting at a downhole depth of 191.95 metres; 5.55 metres averaging 1.11 grams, starting at 206.5 metres; and 5.05 metres averaging 16.17 grams, starting at 384.3 metres.
Stepping out farther to the east, hole 55 intersected 1.57 metres grading 1.37 grams gold at a downhole depth of 199.73 metres.
North of hole 33, hole V97-48 hit 10.26 metres averaging 0.49 gram gold, starting at a 192.15-metre depth. Farther to the north, hole V97-42 cut 2.1 metres grading 7.79 grams gold, starting at a depth of 20.65 metres; 6.2 metres averaging 1.27 grams, starting at 256.2 metres; and 20.25 metres averaging 1.24 grams, starting at 345.45 metres.
Gitennes collared hole 61 in the northern extension of the Alumbre zone based on a combination of exploration techniques, including transient electromagnetic and induced-polarization surveys, detailed geological work by in-house consultants and rock alteration studies performed by Petrascience Consultants using a portable infrared mineral analyzer.
Results of this work suggest Alumbre has a strong epithermal gold signature, and that previous drilling only tested a small portion of the target, which appears to have minimum dimensions of 1,100 by 185 metres. Four new holes have been completed since hole 61.
