ON MEXICO ISSUES
- Karen Flores, was appointed as general director of the Mining Chamber of Mexico (CAMIMEX). It will be the first time since its foundation in 1906 that CAMIMEX will be run by a woman.
- Aloro Mining Corp., released drilling results from the last four holes collared in the southeastern area of its Los Venados project in Sonora for a total of approximately 1,347m drilled. The drilling intersected a felsic dome with 3-10 weight percent pyrite content in pervasive altered volcanic flow units and intrusive dome rock unit up to 200 meters thick. Assay results were discouraging showing very low grade Au, between 0.1-0.2 g/t Au, in scattered intercepts from 1.5-7.6m wide throughout the broad zone of pyritized felsic dome. No more work is planned in this area of the concession.
- Riverside Resources Inc., completed the acquisition of Los Cuarenta project in Sonora from Millrock, where it has identified three targets. The Santa Rosalia target is the highest priority of the 3 targets and is defined by past open cut and underground vein mining where recent sampling has shown a strike length of more than 500 m and open to the east and west.
- Tamino Minerals Inc., announced its business development plan and exploration expenditure guidance for the period 2019-2020. The plan is to identify and acquire high-quality, advanced-stage exploration projects and discover early-stages opportunities that can be strategically tested and quickly progressed to key decision point. Exploration expenditure guidance are planned to be $5M in 2019-2010, with $2M in the Amalia project, $1.2M in the El Volcan project, and $1.8M in other small exploration projects and acquisitions.
- Oceanus Resources Corporation, announced the commencement of the 2019 exploration program at its El Tigre project in Sonora. The Company has recently mobilized the exploration team back to the property to continue prospecting and mapping, as well as, sampling in the area of the Caleigh vein. The objective of this program is to establish drill targets.
- Radius Gold Inc., and Pan American Silver Corp., announced the commencement of the phase 3 drilling program at its Amalia project in Chihuahua. Pan American Silver intends to complete further geological mapping, re-logging of previous drill core, and drilling an additional 2,500 m as part of the phase 3 program.
- Gainey Capital Corp., announced that it has finalized the reparation and construction of approximately 39Km of road and a water reservoir system to support its planned drilling program at its Las Margaritas project in Durango. The company received the approval from SEMARNAT to drill up to 32 targets. Gainey has already awarded the drilling contract and will commence soon a first phase of drilling comprising 2,190m to test 16 drill targets.
- GoGold Resources Inc., released drill results from four new holes drilled at the Main Zone, and underground channel sampling results from its Los Ricos project in Jalisco. Significant intersections were encountered in hole LRGG-19-034 with 0.92 g/t Au and 177 g/t Ag (3.28 g/t AuEq) over 20.1m, including 3.41 g/t Au and 621 g/t Ag (11.68 g/t AuEq) over 4.9m; and in hole LRGG-19-035 with 1.29 g/t Au and 127 g/t Ag (2.99 g/t AuEq) over 24.4m, including 3 g/t Au and 258 g/t Ag (6.44 g/t AuEq) over 9.8m. In addition, GoGold rehabbed the historic El Troce old working where a mapping and channel sampling program was conducted. Encouraging results were obtained with grades varying from 0.98-6.8 g/t Au, and 44-492 g/t Ag over 2-3 m wide. Given the results, the company has decided to move a drill to test the targets at El Troce area.
- Silver Spruce Resources Inc., reported high grade Au assay values from surface rock sampling conducted at its Cocula project in Jalisco. Nine out of twenty six rock chip samples recently taken from surface outcrop returned Au assay values of 0.88 g/t Au up to 12.55 g/t Au, Ag values of 13 g/t Ag up to 53 g/t Ag, and Pb values of 0.2% Pb up to 7.4% Pb. These recent sample assays continue to confirm the presence of widespread Au mineralization at surface, along with Ag and Pb values. The company also announced that it filed the first ever 43-101 technical report for its advanced Au Cocula project. Silver Spruce will continue its due diligence activities designed to support a definitive purchase decision of the property.
- Mexican Gold Corp., discovered a new resistivity anomaly at the Cinco Señores target area in its Las Minas project in Veracruz. This notable TEM resistivity anomaly, similar in size to the El Dorado Au-Cu-Ag resource, extends more than 700m towards the Las Minillas target. The company plans to drill test this anomaly in the near future.
- US Antimony Corporation, reported estimated sales for August 2019. It sold 146.6K Lb Sb and 1159 tons of zeolites. “The Company continues to take steps to reduce its costs of producing Sb products in response to the lower global sale prices.”
- Consolidated Zinc Limited, provided August 2019 production results from its Plomosas mine in Chihuahua. The company mined 2,794 tonnes of 14% Zn, 8% Pb, and 42 g/t Ag, and processed 2,913 tonnes of 13.5% Zn, 8% Pb, and 39 g/t Ag.
- Consolidated Zinc Limited, announced a plan to rise A$3.5M to fund the Plomosas mine operations in Chihuahua, to process the pending sale of Zn-Pb concentrate currently stockpiled, and for working capital. A$2.48M will be rised through pro-rata non-renounceable rights offer, and A$1M through a private placement.

- Defiance Silver Corp., announced that it has applied for TSX Venture Exchange approval to extend by one year the expiry date of an aggregate of 5.75M of outstanding warrants exercisable at $0.45 per share (San Acacio project, Zacatecas).
ON RESOURCES AND DEVELOPMENT
- Almaden Minerals Ltd., provided an update to their shareholders of the progress achieved to build its precious metal Ixtaca mine in Puebla. The company reported that the waste rock and flotation tailings have low potential for metal leaching. It also reported that the mine plan considers a dry stack filtering tailings facility, and co disposal with waste rock with no tailings dam, eliminating the risk of a tailings dam failure. Almaden has received letters from INAH clearing the area for development, from PROFEPA confirming it has conducted exploration work in accordance with the environmental code, and from the authority responsible for indigenous affairs confirming that no indigenous communities are located in the mine impact area. Local community members have publicly expressed their support of the project. One key aspect to develop the Ixtaca mine was the strong support granted for over 800 people from the local community. They signed a declaration of support for the project and delivered to the environmental authorities, and a Memorandum of Understanding has been signed with local water users. The Municipality has included mining as one of its accepted investment and development activities. Based on the FS, an initial investment of USD $174M is required to generate an after-tax internal rate of return of 42% and NVP of USD $310M, using a discount rate of 5% and precious metals prices of USD $1,275/Oz Au and USD $17/Oz Ag. The project would employ over 400 people during an 11-year mine life and would also provide updated infrastructure to a highly marginalized region.
- Discovery Metals Corp., announced mobilization to conduct a 30,000 – 35,000 m drilling program at its recently acquired Cordero project in Chihuahua. The company plans to commence it in about five weeks from now and expect to be completed in twelve months, with the focus of delineating and discovering the highest-grade phases and domains of the mineralized system, and testing new high priority targets. The company has estimated 20,000-25,000m of drilling at the Cordero deposit and 10,000m on six regional areas that require follow-up work and drill testing.
- Azure Minerals Limited, reported that Au-Ag exploration is underway around Mesa de Plata and Loma Bonita deposits on its Alacran project in Sonora. The Mesa de Plata deposit (10.5M tonnes of 82 g/t Ag for 27.4M Oz Ag, including 1.8M tonne of 275 g/t Ag for 15.5M Oz Ag) remains open to the west but is constrained in this direction by the concession boundary. To the north and east the mineralization has been truncated by erosion, however the mineralized zone remains open to the south. Potential for repetitions of Mesa de Plata exist further to the north, where outcropping vuggy silica forms similar-looking silicified ridges. Further exploration is planned for this area. At the Mesa Bonita deposit (5.4M tonnes of 0.9 g/t Au and 28 g(/t Ag for 150K Oz Au and 4.8M Oz Ag), the mineralized zone is constrained to the west by erosion into a valley but remains open to the north, south, east and at depth down-dip. Being open in several directions, there is good potential that further drilling will significantly increase the size of the resource.
- Impact Silver Corp., presented drilling results from its Zacualpan project in Mexico state and extended the mineralization 50m to depth at the San Ramon mine. Significant drill intersections were encountered in hole MPZ-284-19 with 321 g/t Ag, 0.38 g/t Au, 0.19% Pb and 0.60% Zn over 2.62m true width, hole MPZ-285-19 with 1,393 g/t Ag, 2.15 g/t Au, 2.4% Pb, and 6.4% Zn over 1.58m true width and 305 g/t Ag, 0.97 g/t Au, 0.7% Pb, and 1.7% Zn over 1.38m true width, hole MPZ-287-19 with 418 g/t Ag, 0.5% Pb, and 0.5% Zn over 2.14m true width, and hole MPZ-288-19 with 214 g/t Ag, 0.9 g/t Au, 0.1% Pb, and 0.3% Zn over 1.87m true width, and 317 g/t Ag, 0.3% Pb, and 0.4% Zn over 1.22m true width. Known mineralization over the total San Ramon workings has a down dip length of over 500m. Further drilling is planned to further test the extent of this prolific zone.
- Leagold Mining Corporation, announced drilling results from its Los Filos underground and the Guadalupe open pit mines in Guerrero. Highlights from the Los Filos underground mine include 8.86 g/t Au over 45m and 6.59 g/t Au over 15.46m. Highlights from the Guadalupe open pit include 1.4 g/t Au over 32.73m, including 7.71 g/t Au over 2.67m, and 6.2 g/t Au over 10.61m, including 10.55 g/t Au over 5.2m. The drill program at Los Filos will contribute to the reserve base and extend the mine life. At Guadalupe, the drilling program is testing for extensions of the mineralization at depth and also confirming the limited nature of old underground workings prior to open pit mining in this area.
- Orla Mining Ltd., awarded the engineering, procurement, and construction contract for its Camino Rojo project in Zacatecas. Orla expects to begin the detailed engineering work by mid-September to build a mine that begins to produce Au in mid-2021. Au production is expected to average 97K Oz Au per year at an estimated AISC of USD $576 per Oz Au. Orla submitted permits applications to SEMARNAT for the MIA and change of land use at the end of August. The legislated timelines for the review of properly prepared MIA and change of land use applications and mine operating permits for a project that does not affect federally protected biospheres or ecological reserves are 120 working days and 105 working days, respectively, which can be completed concurrently.
- US Antimony Corporation, announced progress on its Au-Ag Los Juarez project in Queretaro. It completed the installation of the ponder liner in the 2 hectares tailings pond and the deepening of the water well to 222m to provide more than 240 gallons per minute. “The pond and the well will be more than adequate to ramp production from 100 tons per day to 400 tons per day. Projects remaining include fencing the pond, completion of the laboratory for fire assaying precious metals, and atomic adsorption equipment for assaying Sb, Ag, and Au in the leach circuit. The mil fine ore bin has been filled with crushed ore from the mine. Initial testing could start within 30 to 60 days.
- Oroco Resource Corp., filed a geological technical report regarding its Santo Tomas project in Sinaloa. “The report summarizes a data set now controlled by the company that comprises 90 historical drill holes totaling 21,075 m, and recommends a significant program of phased surface exploration, deep geophysical surveys, and diamond drilling that aims to verify and build upon a key new geological model and a substantial body of historical drilling, mineral resource estimates, and pre-feasibility studies. The Report provides the company with a current, technical foundation upon which to advance the Santo Tomás project by confirming the technical analysis of the mineralization on the property”.
- Sonoro Metals Corp., reported that a program of 3D modelling, mapping and sampling is underway at its Cerro Caliche project in Sonora. It also launched a phase 3 drilling program to test the Veta de Oro, La Espanola, Cuervos and Guadalupe/Cabeza Blanca zones, where previous scout holes reported intervals of high-grade vein Au mineralization. “The program is a continuation of the company’s strategy of systematically exploring Cerro Caliche as it concurrently advances its proposed heap leach pilot operation (HLPO). Drilling to date continues to outline shallow, bulk tonnage Au mineralized zones with grades similar to operating heap leach mines in the region”.
ON DEALS AND CORPORATE ISSUES
- Almaden Minerals Ltd., appointed its new VP Project Development to oversee detailed engineering and construction of its Ixtaca project in Puebla.
- Golden Goliath Resources Ltd., granted 3M stock options to directors and officers, and 400K to employees and consultants. The incentive stock options are exercisable for a period of five years at a price of $0.10 (San Timoteo project, Chihuahua).
- Golden Minerals Company, announced termination of sale agreement with Compañia Minera Autlan S.A.B. de C.V., regarding the sale of certain of its Mexican properties. The CEO of Golden informed that unfortunately they could not come to terms with Autlan and now they are in position to consider future options for the properties that were included in the Autlan agreement (Velardeña and Rodeo in Durango, and Santa Maria project in Chihuahua).
- Millrock Resources Inc., completed the sale of five of their Mexican properties to Riverside Resources Inc.
