More great results from ARU.
I am hoping that some impatient hot money will flee at the reopen of trading tommorrow because results were not "spectacular", in a relative sense, giving an opportunity to collect some more shares at the closing price today or lower.
-The best news is obviously that ARU continues to hit nice grades and thicknesses on step outs to the N, apparently as far north as line 83700 (700 m strike length now).
-Running a close second in my book, is that they hit the host volcanic package west of the mineralised fault zone at a fairly reasonable depth in hole 61, including a bit of sinter at the conglomerate/volcanic contact. This opens up possibilities for finding gold west of the fault zone in a position relatively down-dropped from the known zone. Although the PR seems to indicate that the interval below the sinter, and west of the fault zone is not gold bearing, I think there is reason to think that gold bearing rock west of the westernmost fault has been offset to the South in addition to down, relative to the known zones. I will go into this idea more below.
-Previously I speculated on the possible presence of a WNW trending fault cutting the gold zone just North of line 9583500.

I think that the fault is there, but based on the drill results, I would now say it cuts across the mineralised zone just south of line 958350, marking the change from the wide, relatively high grade zones on section 9583400 N (holes 57, 58 and 59) to the narrower, lower grade intercepts in hole 62. I agree with those folks speculating on the possibility of a feeder zone underlying the highest grade areas, and throw out the idea that it is centered on the structural intersection of the NNW and NS faults.
-----WNW faults-----
Besides the evidence for the WNW fault zones in linear topographic trends, maybe some of the bigger ones, can be seen in the regional magnetic data:
Possibly the faults show up as sharp contacts between the pink/red and the blue/green aeas. The pink/red marks intrusive rocks associated with the porphyry mineralisation at Camp and Tranca Loma. I think that the two WNW trending intrusive trends were originally a single WNW trending band of intrusives but that the porphyry trend is cut by the NS gold bearing fault zone and that the west side has moved south relative to the east side of the gold bearing fault zone (FDN and B/LP bearing fault zone). In fact, it looks like the B/LP gold zone is intersected on the north and south by WNW structures.
Additional evidence for this lateral sliding of the E and W sides of the fault zone relative to each other occurs in the apparent shape of the Bonza mineralisation lens.
If you stand on one leg, squint and tip your head to the right while looking at the outline of the main B/LP zone <g> in the above figure, you may see what looks like a big, severely flattened S with a fat part in the middle. This shape is referred to as a sigmoid or sigmoidal bend. If this interpretation is correct, it is also indicative that there is lateral movement on the NS fault zone (west side moved south) as well as the vertical movement (west side down) and that this lateral movement was active during gold depostion.
If all this extreme arm-waving is at all correct, it suggests:
-There is a target in the block of rock west of and in contact with the fault zone, south of the currently drilled FDN area, that might represent the faulted off western portion of the currently known high-grade zone that has moved south.
-There may be repeated high grade zones with a shoot-like nature where other WNW striking faults cross the NS fault zone. For example I think there may be another high-grade shoot developing to the north, centered on an area just north of hole 65. I think the funny loop in the river with the white spot in the middle, to the NW of hole 62, marks where the river hits the WNW structure.
-If the NS structure does indeed cut and offset the porphyry trend it suggests that the B/LP hydrothermal system is significantly later than and possibly unrelated too the porphyry hydrothermal system.
I think I will wait for the results of holes 63-65 before making an updated OOM (order of magnitude resource calculation).
Just having fun, all is my interpretation based on data presented on ARU website and is therefore open to major changes as more data becomes available or as if I change my mind about things. |
