ON MEXICO ISSUES

  • Fresnillo PLC and Mag Silver Corp. are awaiting a Supreme Court (Suprema Corte de la Nación) resolution on a mining duty attached to environmental impact, set by the state of Zacatecas. The federal government challenged the State’s right to impose such a duty back in 2017.

ON EXPLORATION

  • Aloro Mining Corp. updated on its exploration of the Los Venados project in Sonora. Mapping and sampling have defined a rhyodacitic volcanic dome associated with high sulfidation style alteration with Au-Bi-Mo anomalies. Several felsic dome/silica breccia complexes have been located, with the highest priority target on the dome at the southeast part of the property, where gold in soil anomalies and IP anomalies coincide. A new environmental report is being submitted to the authorities, seeking permit for 12 reverse circulation holes.
  • Colibri Resource Corp. completed the final 900 m of its 3,000 m phase 1 drilling program on its Pilar project in Sonora. Samples have been taken to the lab and results are pending. A 56 sample soil survey returned 10 samples greater than 0.1 g/t Au, and 3 samples over 1 g/t Au.
  • Colibri Resource Corp. released results from drilling on its Pitaya project in Sonora, by joint venture partner Agnico Eagle. Highlighted results from the last four holes comprise 9 m @ 0.26 g/t Au; 26 m @ 0.19 g/t Au; 34 m @ 0.22 g/t Au. During 2016-2017, Agnico drilled 7,641 m in 27 drill holes.
  • Azucar Minerals Ltd. has begun drilling the North zone and the north end of the Villa Rica zone of its El Cobre project in Veracruz. Preparations for this drilling campaign include surface and soil geologic and alteration focused mapping and sampling. “The current drilling at Villa Rica is focused on the Naranjo zone, a new area of exposed porphyry alteration and mineralisation located approximately 500 metres north of the previous Villa Rica drilling and about 1.2 kilometres south of the Norte Zone.”

ON MINING

  • Mexus Gold US begun mining at the 8 Brothers/370 project in Sonora. “The company has mined 1000 tons of material containing an average of 9 grams Au and 50 grams Ag per ton. This material is currently being run through a crushing system and placed into an aerated VAT holding tank”. Its portable Merril Crowe system has been installed and tested.

ON FINANCING

AZUCAR MINERALS COMMENCES DRILLING AT THE EL COBRE PROJECT, MEXICO

2018-06-13_NR_AMZ

VANCOUVER, B.C. Azucar Minerals Limited (“Azucar” or the “Company”) (TSX-V: AMZ; OTCQX: AXDDF) is pleased to announce that drilling has commenced at its El Cobre porphyry copper-gold project in Veracruz State, Mexico. The last few months have been spent preparing for this drill campaign with surface and soil geologic and
alteration focused mapping and sampling, core relogging and drill site preparation work. Drilling is currently underway at the Norte zone and at the very north end of the Villa Rica target which is located south of the Norte zone. At the Norte zone, step out and infill drilling has been planned to define the size and provide appropriate drill density for potential resource definition in the future. The current drilling at Villa Rica is focused on the Naranjo zone, a new area of exposed porphyry alteration and mineralisation located approximately 500 metres north of the previous Villa Rica
drilling and about 1.2 kilometres south of the Norte Zone. The Company anticipates drilling to be underway with one or more rigs throughout the course of 2018 in order to test all targets currently defined.

This vein is parallel to the Babicanora and Babicanora Norte veins and is approximately 400 metres southeast of Area 51, which is the highest-grade mineralized area of the Babicanora Vein having average resource grades greater than 1,000 grams per tonne (“gpt”) silver equivalent (“AgEq”, defined below). There are 23 known epithermal veins on the Property, including 11 which have drill-intersected high-grade mineralization and consist of the Babicanora, Babicanora Footwall, Babicanora Norte, Las Chispas, Giovanni including La Blanquita, William Tell, Varela, Granaditas, Luigi and Amethyst veins. Five of the 23 veins have been included in the maiden resource (refer to “Technical Report and Mineral Resource Estimate for the Las Chispas Property, Sonora, Mexico”, effective February 12, 2018 and amended May 9, 2018).
