GREAT PANTHER SILVER CONFIRMS CONTINUATION OF GOLD-SILVER MINERALIZATION AT SAN IGNACIO MINE
Surface drilling at Great Panther Silver Ltd.'s San Ignacio mine, part of the Guanajuato mine complex (GMC), has confirmed the continuation of strong gold-silver mineralization along strike of the current mine workings.
The drilling, which is continuing, initially targeted the southeasterly strike extension of the Melladito vein structures, in particular, where this vein set is intersected and cut by, the Plateros vein trend. The result of this intersection is a thickening of the veins, highlighted by hole ESI16-174, which returned a combined estimated true width of 19.24 metres averaging 6.36 grams per tonne gold and 261 g/t silver. This comprised 4.65 metres of 4.81 g/t Au and 275 g/t Ag in the Melladito vein and 14.59 metres of 6.86 g/t Au and 257 g/t Ag in the Plateros vein. The extent of this thicker portion of vein intersection is not yet known and additional drilling and mine development will be required to determine its size and significance. Nonetheless, several other holes returned excellent indications of high gold and silver grades as presented in the associated table.
"We are encouraged by the continuation of mineralization to the southeast of our mine workings, with the Plateros vein locally exhibiting very high grades, particularly in gold,"
stated Robert Archer, president and chief executive officer.
"The results of our exploration drilling have given us sufficient confidence to commence drifting in that direction to further evaluate and delineate these zones from underground."
The surface exploration drilling program began in October, 2016, and comprised
32 holes for 7,464 metres to April 24, 2017, at a horizontal and vertical spacing of approximately 50 metres. Hole ESI16-174 was drilled approximately 400 metres grid south of the current mine workings and stepout drilling continued sporadically along strike for another 900 metres. Drilling has now changed focus to the Purisima vein, approximately 650 metres to the west of the current mine workings.
