Eleven drill hole locations have been selected to test the three geophysical anomalies and two geochemical targets. One World intends to commence drilling on the latter part of October 2018.

ON MINING

  • Hecla Mining Co. reported second quarter 2018 results, including figures from its San Sebastian project in Durango, where 559,647 Oz Ag, 3,872 Oz Au were produced during the period. The mill operated at an average of 415 tpd (tons per day). Cash cost was $9.79 per Ag Oz and AISC $17.15 per Ag Oz, reflecting the higher cost of transitioning from open pit to underground mining. “A reduction in per ounce costs is expected in the second half of the year as underground production continues to ramp up”.
  • Torex Gold Inc. reported its financial results for the second quarter 2018. Mine production at Limon-Guajes totaled 7.15 Mt (tonnes), averaging 78,629 tpd (tonnes per day) of which 1.28 Mt was ore processed at 11,140 tpd. Mined ore averaged 2.45 g/t Au and processed ore 2.86 g/t Au, for the production of 78,796 Oz Au, with 87% Au recovery in the period and cash cost of $680 per Oz Au and AISC of $1,017 per Oz Au. Cash held at the end of the period was $117.9 M.
  • Golden Minerals Co. announced financial results for the second quarter 2018. During the quarter Golden reported final drill results from the Santa Maria project (Chihuahua) 2017-2018 drill program and announced the preparation of an updated technical report and preliminary economic assessment (PEA). In August 2018, Golden entered into a non-binding letter of intent with The Electrum Group LLC upon which Electrum is to purchase Golden’s remaining interest in the Celaya property in Guanajuato for a payment of $3 M. Cash and cash equivalents stood at $2.5 M at the end of the period.
  • Argonaut Gold Inc. released financial results for the second quarter 2018. During the period the company produced 38,441 GEOs (Gold equivalent ounces) at cash cost $704 per Oz Au and AISC of $832 per Oz Au. At El Castillo, in Durango, 2.22 Mt (tonnes) of waste, and 2.15 Mt (tonnes) were moved, with 2.12 Mt ore @ 0.37 g/t Au crushed to the pads to produce 10,079 Oz Au, 8,111 Oz Ag at cash cost $992 per Au Oz. At San Agustin in Durango, 618 Kt of waste, 1.85 Mt of ore were moved, with 1.88 Mt of ore @ 0.36 g/t Au crushed to the pads to produce 15,528 Oz Au, 55,781 Oz Ag. At La Colorada, in Sonora, 1.81 Mt of waste, 1.06 Mt of ore were moved (32 K tpd), with 1.14 Mt of ore @ 0.36 g/t Au crushed to leach pads to produce 11,503 Oz Au, 29,360 Oz Ag at cash cost $833. “The Company expects the third quarter 2018 will see lower production due to the lower grades stacked on the leach pad during the second quarter 2018 and also expects higher costs during the third quarter 2018 associated with drilling, blasting and hauling costs for normal state operations”.” While the Company’s explosives permit has been reinstated at La Colorada, the legal action brought against the Secretary of National Defense and the Municipality of La Colorada continues through the Judiciary court process”.
  • Alio Gold Inc. reported second quarter 2018 results. The San Francisco mine in Sonora produced 14,466 Oz Au, 7,661 Oz Ag at by-product cash cost $950 per Oz Au, while AISC was $1,172 per Oz Au. The Company is reducing stripping and focuses mining on more profitable ounces to maintain cash neutral operations. As a result of the reduced stripping, the ”production guidance of 90,000 to 100,000 ounces of gold for 2018 will not be met.” At Ana Paula in Guerrero, all development work including the construction of the underground decline, the completion of the feasibility study and further exploration have been temporarily suspended as result of the recent decline in the gold price.
  • Odyssey Marine Exploration Inc. reported second quarter 2018 results. “Odyssey holds a controlling interest in Oceanica Resources, S. de R.L., and ExO, a subsidiary of Oceanica. ExO controls exclusive 50-year mining permits in an area in Mexican waters that contains a large amount of phosphate mineralized material”.” On March 21, 2018, the 11-judge panel of the Superior Court of the Federal Court of Administrative Justice in Mexico ruled unanimously in favor of ExO, nullifying the original denial of the environmental permit application.“ (Don Diego, Pacific Ocean cost of Baja California Sur)

ON FINANCING

  • Harvest Gold Corp. closed a fourth and final tranche of its non-brokered private placement to raise CDN$200 K for a total of CDN$857 K gross proceeds. “The Company paid finder’s fees of 8% cash and 8% warrants to Canaccord Genuity Corp. on certain funds”. Harvest delivered $700 K to Evrim Resources Corp. to fund the Cerro Cascaron project (in Chihuahua) drill program of up to 3,000 m, beginning the third week of September.

ON RESOURCES AND DEVELOPMENT

Additional oxide mineralization is being defined along the Professor and East Francine veins. On the Francine vein mineralization has been traced for over 360 m on surface, and over 240 at depth, but once incorporated the newly defined East Francine vein the total strike length of continuous mineralization along the Francine Vein exceeds 2,400 m and can be traced to a depth of over 600 m.

  • San Marco Resources Inc. signed an earn-in agreement with Antofagasta plc on the Chunibas project, located in Sonora. Antofagasta can acquire a 70% interest in the project by spending US$8 M in exploration, and making cash payments on the aggregate of US$200 K over a period of 4 years. A firm commitment of US$700 K will be used primarily for an initial drill program, including $100 K of reimbursement to San Marco of recent exploration expenditures. “The Project consists of stratiform, volcanic hosted coppersilver mineralization, similar to several ore deposits in northern Chile and is a style of mineralisation not previously discovered in Mexico.”

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.

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.

The mineralized body has a strong magnetic signature, extending for 300 m by 150 m and modelling of the magnetic data indicates a considerable vertical extent. The best intercept from the previous drilling was 26.2 m @ 9.5 g/t Au, 1.26% Co.
