In a move that places it in a historic Mexican mining region,
Robex will acquire the property in exchange for US$500,000, payable in instalments over two years. The current mining concession expires in 2029 and covers a 44-ha parcel, including a former silver-lead-zinc mine.
Mining in the area dates from the 15th century, when high-grade veins were worked for native silver and for oxidized lead mineralization. A small-scale underground operation ran until about 1996.
Robex plans to take a 9,000-tonne bulk sample from workings at a 75-metre depth and drill from the workings to vertical depths of around 150 metres, where flat-lying manto-type mineralization was intersected in earlier underground drilling. One drill hole cut a 22-metre section of sulphide mineralization grading 514 grams silver, plus 22.3% zinc and 8% lead, in a limestone host rock.
