Goldrush drills seven m of 3.13 g/t Au at Ronguen

Mr. Len Brownlie reports

NORTH ZONE EXTENSION DRILLING INTERSECTS UP TO 3.13 G/T GOLD OVER 7 METRES, AND TRACES NEAR SURFACE MINERALIZATION AT RONGUEN GOLD DEPOSIT, BURKINA FASO

Goldrush Resources Ltd. has released assay results from the latest drilling program at its flagship Ronguen gold deposit in Burkina Faso, West Africa. Highlights of the program include:

  • 3.13 grams per tonne (g/t) gold (Au) over seven metres in reverse circulation (RC) hole KGRR12-258;
  • 2.22 g/t Au over three metres and 2.02 g/t Au over five metres in RC hole KGRR12-256;
  • 1.87 g/t Au over four metres in RC hole KGRR12-259.

Len Brownlie, president and chief executive officer of Goldrush, noted: "The North zone drill program has confirmed the presence of gold mineralization over a 620-metre strike extension of the North zone that was not previously included in the July, 2012, resource estimate update. The drilling demonstrates the continued prospectivity of the Ronguen deposit area."

"Over the coming months, Goldrush will advance Ronguen through the completion of a preliminary economic assessment, which will identify the best choices for near-term production and quantify the economics of the deposit at this stage. Goldrush also intends to continue the exploration of other targets in proximity to the Main zone," Mr. Brownlie added.

Key technical details

Eighteen RC drill holes totalling 1,045 metres tested shallow oxide mineralization associated with a previously undrilled 620-metre western extension of the North zone. The North zone consists of mineralization that responds to induced polarization resistivity surveying and is subparallel to the Main zone of the company's Ronguen gold deposit.

The Main and South zones of the Ronguen deposit currently have delineated 332,000 measured and indicated ounces averaging 1.22 g/t Au, and 52,000 inferred ounces averaging 1.85 g/t Au over a strike length of 1,700 metres. The majority (309,000 ounces gold) of the measured and indicated resources are in the oxide category and amenable to lower-cost heap leach processing.

To assist in the delineation of additional oxide resources, an induced polarization survey was completed over the Ronguen deposit and interpreted with newly acquired software with the ability of 3-D imaging. Analyses of the results provided excellent coincidence between the resource and high-resistivity anomalism.

Two identified adjoining resistivity anomalies with subparallel strike directions provide promising targets, with the western extension of the North zone anomaly investigated by 18 shallow RC drill holes over a strike length of approximately 620 metres.

Eight holes (from east to west: KGRR12-253, -256, -255, -254, -257, -258, -259 and 260) were drilled from grid G1, line 880E, to grid 2, line 590E, a distance of approximately 360 metres, to test the western extension of the resistivity anomaly axis that correlates with the North zone mineralization to the east. Seven RC holes (from east to west: KGRR12-270, -261, -262, -263, -264, -265 and 269) tested a portion of the resistivity anomaly immediately to the southwest, from grid G2, line 540E, to grid G2, line 300E, a distance of about 260 metres. Three RC holes (from east to west: KGRR12-267, -266 and -268) tested the resistivity anomaly trending northwesterly from grid G2, line 470E, to grid G2, line 350E, a distance of 120 metres. Grid G1 is the easternmost, while grid G2 is the westernmost of the two overlapping grids at the Ronguen deposit.

A shallow test of the North zone gold mineralization and associated resistivity anomalism was completed on each section. Nine holes intersected the metasediment-diorite contact, which is an important rheologic control for the gold mineralization at Ronguen. Eight of the holes (KGRR12-254, -260, -261, -262, -266, -267, -268 and -270) that failed to intersect this contact did not contain gold values above a level of 0.4 g/t Au, although only holes -260, -266, -268 and -270 were devoid of gold. Perterbations along the metasediment-diorite contact may have been responsible for it not having been intersected and tested by the short drill holes.

The RC drill hole lengths varied from 40 metres to 72 metres, and the holes were drilled at inclinations between minus 51 degrees and 56 degrees. A total of 1,045 metres was drilled in the 18 RC holes, which were continuously sampled for assaying at one-metre intervals.

Ronguen exploration plan

Eighteen holes totalling 1,045 metres were completed in the fall 2012 drilling program on the Ronguen gold deposit. A total of 231 linear metres in two trenches on the South zone and a 12-metre deep pit on the North magnetic target have been completed as well. The samples from the excavations have been delivered to the assay laboratory and results are pending.

Ronguen deposit mineralization

The Ronguen gold deposit is located within the northeastern part of the highly prospective Birimian-age Boromo greenstone belt in Burkina Faso. The local geology at Ronguen is dominated by an east-northeast-trending metasedimentary sequence consisting of interlayered siltstone, mudstone and minor conglomerate that are intruded by plugs, and narrow dikes and sills of gabbroic composition. The Ronguen mineralized zone is located in the structural hangingwall of a major east-northeast thrust fault, which recorded a tectonic transport direction toward the north. The mineralized deformation corridor represents a major east-northeast-trending reverse fault zone, dipping moderately toward the south. Gold mineralization is found in both metasedimentary and mafic intrusive rocks. The gold mineralization is associated with quartz-carbonate veins/veinlets, and with sulphides occurring as disseminations and patches and in veinlets. Two sets of gold-bearing quartz veins are developed: subvertical shear veins parallel to the shear zone foliation and to the shear zone boundaries, and subhorizontal extension veins. Small quartz stockworks are present and represent a part of the gold mineralization.

Quality assurance/quality control

Goldrush maintains a rigorous quality-control program involving the use of certified standards from an accredited Canadian laboratory, inserted blanks and the use of repeat assays. Details of Goldrush's quality-control program were provided in the company's news release dated Oct. 25, 2010.

The SGS laboratory in Ouagadougou, Burkina Faso, was used for sample analysis. Samples are assayed using standard fire assay techniques on a 50-gram charge with an atomic absorption finish. For its internal control, SGS inserted two certified standards and one blank and analyzed one random duplicate for approximately each 25 samples submitted. For its certified standard and blank samples included in the quality-assurance/quality-control procedure, Goldrush averaged 7.5 per cent of the total samples submitted.

The RC drilling was contracted to Forages Technic-Eau/Burkina sarl based in Ouagadougou, Burkina Faso.
