Stratabound drilling expands Mexican polymetallic property

Drilling at the Sierra Azul lead-zinc-silver property in Mexico’s Coahuila state has extended mineralization down dip from the past-producing Santa Genoveva mine.

Owner Stratabound Minerals (SB-A) reports that mineralization was intersected 150 metres below the lowermost workings, along a minimum strike length of 350 metres. Previous owners had mined 4,000 tonnes of material grading 12% zinc, 4% lead, 30.9 grams silver per tonne and 0.25 grams gold.

Stratabound drilled four holes, with the first and third collared at the same location but drilled in opposite directions in order to test the hangingwall and footwall. The second hole, collared nearby, was drilled vertically. Hole 4 was collared 100 metres to the south and drilled into the footwall.

Highlights include: 34.55 metres (21.45-56 metres) grading 2.44% zinc, 0.49% lead and 3.26 grams silver per tonne in hole 1; 27.65 metres (44.35-72 metres) grading 6.42% zinc, 2.07% lead and 3.9 grams silver in hole 2; 6 metres (71-77 metres) grading 1.63% zinc, 0.54% lead and minor silver in hole 3 (which was lost in a zinc-enriched sandstone unit); and 18 metres averaging 2.16% zinc, 2.3% lead and 2.22 grams silver in hole 4.

The mineralization in holes 1, 2 and 4 also included several higher-grade intervals. As well, holes 1 and 4 both intersected one separate, but narrower, interval with metal concentrations similar to those reported above.

Mineralization at the Santa Genoveva deposit is associated with oxidized and fresh dolomite and sandstone units. A 500-metre-long chargeability anomaly coincides with the deposit, which remains open along both dip and strike directions.

Drilling is continuing.

Stratabound also reported the discovery of several old workings along strike from the Santa Genoveva deposit in both directions. Samples taken from the workings varied from 0.62% zinc, 1.33% lead and 25 grams silver to 37.7% zinc, 1.35% lead and 3 grams silver.

The new showings, which extend the known strike length of mineralization at Sierra Azul to 3.7 km, have prompted Stratabound to stake another 1,500 ha to the north and to option two claims, covering a total of 353 ha, to the east and west of the property. As a result, the company now owns, or has the right to earn a 100% interest in, 40 sq. km of prospective stratigraphy in the area.
