ON EXPLORATION

  • Endeavour Silver Corp. disclosed drilling results from its Parral properties in Chihuahua. At the San Patricio vein system 8,846 m of core drilling have been completed over 1400 m of strike length. “Three mineralized areas were intersected, of which the largest and central zone now measures 600 m long by 250 m vertical (starting 150 m deep) by 1-3 m true thickness, still open to the south and at depth”. Highlighted true width (TW) intercepts include 2.1 m @ 303 g/t Ag, 0.05 g/t Au, 0.4% Pb, 0.5% Zn; 1.0 m @ 678 g/t Ag, 0.22 g/t Au, 3.5% Pb, 0.9% Zn; 3.0 m @ 689 g/t Ag, 0.24 g/t Ag, 1.6% Pb, 1.1% Zn; 1.6 m @ 293 g/t Ag, 0.27 g/t Au, 3.5% Pb, 7.6% Zn; 2.3 m @ 1,660 g/t Ag, 0.72 g/t Au, 6.5% Pb, 14.4% Zn. Metallurgical recoveries from core samples with flotation and leaching tests include 47% Ag from Sierra Plata (oxide), 98% Ag on El Verde (mixed), 95% Ag on Remedios-Argentina (mixed), 94% Ag and 93% Au on Palmilla (oxide) and 91% Ag and 86% Au in Cometa-San Juanico (mixed).
  • San Marco Resources Inc. announced it was awarded the Espiritu 2,712 ha SMR concession in the recent mineral concession lottery by the Mexican government. The property is less than 30 km SE from San Marco’s Chunibas and 1068 projects in the Sahuaripa district. “Espiritu SMR overlies a window of pre-mineral cretaceous volcanic and sedimentary rocks intruded by Laramide age granitoids”. Previous operator in the area, Kootenay Silver Inc. stated: “An extensive area of polymetallic vein, stockwork, breccia and gold-copper porphyry mineralization”. A porphyry copper setting and a vein and stockwork zone of precious and base metal mineralization are separated by a major fault. Selected drill hole intercepts include 48.0 m @ 0.19 g/t Au, 0.1% Cu; 220.5 m @ 0.14 g/t Au, 0.15% Cu. San Marco is preparing to do a first-pass ground validation and prospecting.

  • Kootenay Silver Inc. optioned the Copalito project in Sinaloa (See below). “The Copalito Project covers a gold and silver epithermal vein system comprised of numerous veins, with individual veins currently traced over strike lengths up to 2 kilometres. Veins vary in width from 0.5 to 10 meters at surface and grade from background to highs of 7.2 gpt gold and 1,620 gpt silver in grab samples”. Vein textures indicate a low or intermediate sulfidation vein system.
  • Millrock Resources Inc. is beginning a second round of drilling at its La Navidad project in Sonora. The target in the project is orogenic gold mineralization, bulk mineable run-of-mine oxidized deposit. The 1,650 m program aims to drill 150 – 250 m in depth in seven holes, testing areas of gold soil anomalies that now are supported by gold anomalies in trenches. The strongest anomalies occur in folded, faulted metasedimentary rocks of Jurassic age, in close proximity to diorite and monzonite dikes. An induced polarization survey has identified low angle structures conducive of orogenic gold deposits. A 1.4 km of trenching on 16 trenches has been completed, with multiple intervals of anomalous gold, like 18.0 m @ 0.56 g/t Au, 24.9 m @ 0.32 g/t Au, 18.2 m @ 0.20 g/t Au, 10.9 m @ 0.38 g/t Au.

A 40 line-km controlled source audio-magnetotellurics (CSMAT) is planned on potential mineralization under shallow cover. A 3,000 m program is expected to commence on July.
  • Discovery Metals Corp. disclosed assay results of 152 samples from its Minerva project in Coahuila. “Minerva encompasses Ag-Pb-Zn mineralization hosted in skarns, mantos, chimneys and breccias”, similar to La Encantada mine 30 km to the East. The mineralization is located along the margin of a polyphase granitoid intrusive body, with ample zone of shallow gravel cover. At La Tercia prospect, channel samples returned 0.8 m @ 30 g/t Ag, 2.3% Pb, 4.6% Zn; 2.0 m @ 249 g/t Ag, 6.9% Pb, 0.1% Zn; 4.0 m @ 37 g/t Ag, 1.6% Pb, 0.2% Zn; 0.6 m @ 3.8% Pb, 0.4% Zn; 0.6 m @ 84 g/t Ag, 5.8% Pb, 0.2% Zn. At Concordia samples returned 0.8 m @ 1,775 g/t Ag, 14.5% Pb, 40.3% Zn; 0.7 m @ 51 g/t Ag, 2.6% Pb, 0.4% Zn; 0.4 m @ 11 g/t Ag, 0.4% Pb, 25.8% Zn.

Mill recoveries averaged 88.4% Au, 57.4% Ag. Also during the quarter the Altiplano facility received 373 tonnes of concentrate containing approximately 805 Oz Au and 26,813 Oz Ag.

ON FINANCING

  • SilverCrest Metals Inc. completed its prospectus offering for gross proceeds of $17.25 M, including the exercise of the over-allotment option in full. The company paid the underwriters a cash commission of up to 6% of the gross proceeds of the offering.

  • Azure Minerals Limited, identified a 500m long by 250m wide strong zinc and lead soil anomaly at its Mina Blanca prospect within the Oposura project in Sonora and is coincident with high-grade mineralization from a rock sample collected in the Mina Blanca old working. Soil samples were tested with a portable XRF analyzer, with values reaching highs of 0.32% Zn and 0.15% Pb. The rock sample from the Mina Blanca old working returned 1.71 g/t Au, 1,600 g/t Ag, 4.6% Cu, 1.6% Pb, and 2.8% Zn. Azure announced further exploration plans, including drilling for its Oposura project.
  • Mammoth Resources Corp., announced results of two holes drilled at its Tenoriba project in Chihuahua in the Moreno and Masuparia areas. El Moreno area drill hole intercepted 7.2m of 0.23 g/t Au, 36 g/t Ag and 3.59 % Cu, while the Masuparia area hole returned 27m of 0.51 g/t Au from 28m depth, including 8.4m of 1.30 g/t Au, and 23.5m from 70m depth of 1.30 g/t Au, including 10m of 2.9 g/t Au and 5m of 4.9 g/t Au.
  • Golden Minerals Company, drilled 8 holes in its Mogotes project in Durango, with low grade gold mineralization intercepted on 2 holes. The epithermal system seems to be deeper than the surface geochemical values initially indicated. Additional mapping and sampling is ongoing in the northern portion of the property.
  • Defiance Silver Corp., carried out an IP survey at its San Acacio project in Zacatecas. The IP survey identified a 200m long by 300m wide target along the underexplored 900m Veta Grande vein, and requires an additional IP survey to close off the anomaly on the property. This undrilled target has the potential to host a virgin silver ore shoot at depth.
  • Advance Gold Corp., announced plans to carry out underground mapping & sampling at its Tabasquena mine in Zacatecas, along with an IP survey followed by a drill program. The aim of the IP survey is to delineate the veins and trace their extension along strike.
