ON MEXICO ISSUES

  • A gold nugget weighing 850 grams was found in La Cienega area, south of Pitiquito in Sonora. The nugget was discovered using a metal detector by a local gambusino. Northwest Sonora is known by the presence of orogenic gold style deposits, like La Herradura, Nochebuena, La Choya, San Francisco and El Chanate. This type of ore deposits has produced large gold nuggets, of up to 12 kg in weight, with the most famous specimens coming from the El Boludo, La Cienega and Tajitos gold placers.

ON EXPLORATION

  • Colibri Resource Corp. has begun phase 1 of its 2018 drilling program on its Pilar property in Sonora. The program envisages up to 30 holes to be drilled focusing on modelling and extending the known mineralization of the Main Zone to the northwest and southwest along trend. “To date, Colibri has defined an in-house resource of 700 K tonnes @ 1.9 g/t Au”.
  • Kootenay Silver Inc. informed on advances on the current drill program at its La Cigarra property in Chihuahua. Six holes have been completed, and one more is in progress at La Borracha zone, which is the extension of the structure that hosts La Cigarra resource, and drilling has now tested 1,000 m of strike length beyond the resource. Results will be disclosed once all assays have been received. The next drill target is the newly identified Nogalera gold zone, with 8 holes planned on anomalous mineralization over more than 1,000 m of length. Once Nogalera has been drilled, the 104-Vein on the southern part of La Cigarra resource is to be drill tested.
  • Azure Minerals Ltd. updated on work being done at its Oposura project in Sonora. Drilling along strike of an outcrop carrying up to 59.6% Pb+Zn on the West Zone intersected high grade mineralization over an area of 400 x 400 m.

Highlights on the Second Week of March, 2018. Mining and Exploration News in Mexico

By Jorge Cirett

During the 10th week of the year (March 5th to March 11th, 2018), at least 24 press releases were announced by companies working in Mexico, and three articles on mining matters in Mexico published by newspapers. ON MEXICO ISSUES, the Fraser Institute released the results of the 2017 survey on Mining Attractiveness by Jurisdiction, with Mexico stagnant at mid table due to low results on taxation regime, labor disruptions and security perception. The Sonora government is supporting the mining industry with the signature of a collaboration agreement with the Economy Bureau. The governors of Chihuahua and Oaxaca attended the PDAC in Toronto for promoting mining investment in their respective states. Other delegations present were from Durango and Zacatecas. ON EXPLORATION, In Sonora Riverside announced a bigger land position at its Cecilia project; Oceanus has mapped the favorable El Tigre Formation rock package for 5 km in strike length at its El Tigre property; Mexus Gold updated on exploration of its 8 Hermanos property; Millrock disclosed interesting low grade drilling results from its Navidad property; Azure has started the second drill campaign at its Sara Alicia Au-Co property. In Chihuahua VVC Minerals received the permit for drilling its Samalayuca property; Radius updated on exploration at its Amalia project. In Guanajuato, Vangold started the phase two of drilling at its Pinguico property. ON MINING, two companies, Americas Silver and Santacruz Silver presented production results for the quarter and/or full year 2017. Magellan Gold announced the restart of its mill in Nayarit.  ON FINANCING, Canuc Resources closed a $1.1 M financing round, Colibri closed the first tranche of a financing round netting $1.08 M. Vangold announced the opening of a financing round for raising up to $2 M. Santacruz Silver obtained a US$2.3 M private loan. Starcore closed a financing round for $125 K with an insider.  ON RESOURCES AND DEVELOPMENT, Levon Resources released an updated mineral resource report for its Cordero project in Chihuahua. Alio Gold provided an exploration update at its Ana Paula project in Guerrero. Leagold updated its mineral resource estimate for its Los Filos mine and the Bermejal Underground deposits in Guerrero. ON DEALS AND CORPORATE ISSUES, Sonoro Metals acted on the LOI to option a group of properties adjacent to its Cerro Caliche property in Sonora. Autlan is to acquire all shares from Metallorum (it already controls an undisclosed percentage), which owns the Lluvia de Oro mine in Sonora.

ON MEXICO ISSUES

  • Mexico stays about the same on the investment attractiveness index published yearly by the Fraser Institute. Mexico fell to the 50 (of 91 jurisdictions surveyed) position from the 44 (of 104) on the 2016 survey, affected mainly by low rankings in security, taxation regime and labor regulations/work disruptions. In 2014 Mexico was on the 24 position of 122 surveyed. Chile ranked 8 and Peru 19 on the 2017 survey. Below is the table for the perception of the taxation regime (which presents the effect of the recently imposed royalties as a hard fact). The security perception ranking, along the other rankings can be seen at the following link: (https://www.fraserinstitute.org/sites/default/files/survey-of-mining-companies-2017.pdf).Taxation Regime Index, Fraser Institute 20171
  • The Sonora government is supporting the development of the mining industry in the state with the signature of a collaboration agreement with the Economy Bureau (Secretaría de Economía). The agreement looks to promote investment, better technical assessments, training and cut red tape. The mining industry represents 17% of the state’s GDP, with the state providing 31% of Mexico’s mining production. Sonora’s Governor Claudia Pavlovich has been pushing a proposal on the Deputies Chamber to install a 100% deduction of exploration expenses on the year these are incurred.
  • The governors of Chihuahua and Oaxaca attended the PDAC in Toronto Canada to promote mining investment on their states. Both Javier Corral (Chihuahua) and Alejandro Murat (Oaxaca) attended the Mexico Mining Day 2018 and had personal interviews with companies doing business in their states or trying to set a foothold there. Other delegations present were from Durango and Zacatecas.

ON EXPLORATION

  • VVC Minerals Corp. received the permit for drilling at its Samalayuca property in Chihuahua. The SEMARNAT permit approved 22 new drilling sites, in addition to 13 already approved. The drilling is to focus on La Gloria Extension area, La Concha pit area, La Zorra zone and the Julianna, Suerte and Trinidad areas. The completed and proposed drilling cover 7 Km of strike length on the property.
  • Vangold Mining Corp. concludes phase 1 drilling, starts phase 2 drilling at El Pinguico property in Guanajuato. Vangold completed five of 15 drill holes targeting the underground stockpiles (backfill) on the El Pinguico vein, with poor recoveries and grades. While a better method of assessing these stockpiles is researched, the company has initiated the phase 2 drilling campaign targeting the lower El Pinguico vein extension below the old workings, 300 m below the surface.
  • Riverside Resources Inc. announced that it has been granted the mineral rights to the Cecilia 1 concession, increasing the ground held on the Cecilia project in Sonora to almost 6,000 hectares. Epithermal Au-Ag mineralization is associated to a rhyolite flow-dome setting.
  • Oceanus Resources Corp. updated on its exploration efforts on El Tigre property in Sonora. The El Tigre Formation is the rock package that host the historic El Tigre mine, which operated from 1903 to 1938, producing 353 K Oz Au and 67.4 M Oz Ag; the favorable El Tigre Formation has been now traced for 5 km.
  • Mexus Gold US. presented an update on exploration of its 8 Hermanos and Scorpio_370 claims in Sonora. Mexus controls 2,800 hectares in an area with sedimentary rocks intruded by granodiorite, dioritic dikes and a diorite porphyry, all covered in turn by Tertiary volcanic tuffs and flows. Three samples from the 370 concession returned 9 g/t Au, 41 g/t Ag; 47 g/t Au, 33 g/t Ag; 10 g/t Au, 8 g/t Ag. Porphyry copper potential is highlighted on a report (no alteration is described).
  • Radius Gold Inc. provided an update on exploration at the Amalia project in Chihuahua. The 10,380 ha project has Au-Ag mineralization defined over 2 km of strike length in high level chalcedonic veins, stockworks and breccias and deeper level structurally controlled higher grade mineralization. “Radius continues to advance the Amalia project and is currently permitting drilling and bulldozer trenching.” Recent channel sampling returned 4.5 m @ 10.3 g/t Au, 202 g/t Ag, extending the total strike length of the high-level epithermal mineralization of the Campamento zone to 500 m.
  • Millrock Resources Inc. reported on first phase core drilling at its La Navidad project in Sonora, funded by earn-in partner Centerra Gold. In total, 2,130 m were drilled in 12 holes, with several anomalous intersections, like: 17.2 m @ 0.75 g/t Au (including 1 m @ 9.05 g/t Au); 15.65 m @ 0.60 g/t Au; 18.30 m @ 0.33 g/t Au; 18.0 m @ 0.12 g/t Au; 6.00 m @ 0.26 g/t Au; 5.90 m @ 0.45 g/t Au; 57.0 m @ 0.29 g/t Au; 16.6 m @ 0.35 g/t Au.
  • Azure Minerals Ltd. announced the start of the second drilling campaign on its Sara Alicia project in Sonora. “The Sara Alicia mineralised zone consists of carbonate rocks intruded by a porphyry. This intrusive event caused strong alteration and mineralising reactions in the limestones to form a skarn body which hosts massive and semi-massive sulphides containing the cobalt and gold mineralisation”. The first phase of this drilling campaign is to comprise 1,000 m in 10-12 holes, targeting along-strike and down-dip extensions. The second phase is planned to complete a 50 x 50 m drill pattern over the mineralized body.

ON MINING

Highlights on the Second Week of January, 2018. Mining and Exploration News in Mexico

By Jorge Cirett

Leisure is the mother of all vices, according to an old Mexican proverb, and having ample spare time during the worst part of the down cycle in the mining industry during 2015 led to creation of this weekly newsletter. First by fueling the creation of the Gambusino Prospector site to publish exploration and mining news, and then noticing that in mid-late 2015 there were news releases worth compiling and spreading, like the private raising of noticeable amounts of cash, and then by compiling the news releases by areas of interest. It was a matter of trial and error until a workable format was born. And remember, there was time available, as the downturn was not throwing much work in our way. The bottom of the downturn was felt in early 2016, with raising spirits in March after PDAC, spirits that continued high through May and Midyear. Things were looking brighter through the end of 2016, but it would take until 2017 for work to noticeably increase in Mexico.  The past year has brought relief to drillers and laboratories, as well as some work for geoscientists and other professionals of the exploration area, but full work is still to come. The expectations for this year are high, even if a swing to a full boom is not expected, but a clear optimistic mood can be perceived in the exploration industry. Having said that, compiling and publishing the news releases takes a two or three hours every week day, and compiling, writing and publishing this newsletter takes anything from four hours (a few times in the year) to up to 12 hours in the more extreme cases…… every week of the year. Believe me, we have learnt to dread the times of the year when the quarterly reports are released. Writing the highlights every week is both a pleasure and hard work that satisfies and exhausts. For the last two years Miguel Heredia was taking care of finding and publishing the press releases from companies working in Mexico and I was doing the compression of the information in a few pages. We now have the help of Laura Ramirez in the research and publishing phase, and starting next week Miguel Heredia and I are to start sharing the task of producing the newsletter in alternate weeks.

During the 2nd week of the year (January 8th to January 14th, 2018), things come back to normal with at least 30 press releases being announced by companies working in Mexico. ON MEXICO ISSUES, the illegal blockade at El Limon-Guajes mine in Guerrero continues. A government sanctioned process to set a date to clear the issue will be held at the end of the month (the end of the month!). ON EXPLORATION, in Sonora, Riverside is awaiting drill results from its Glor and Clemente projects and announced its intention to drill during 2018 its Cecilia project; Canuc informed the delineation of several breccia bodies at its San Javier project; San Marco released high-grade copper results from a new zone at its Chunibas project. In Chihuahua Golden Goliath is in the process to select drill targets at its San Timoteo project. In Coahuila, Silver Bull announced high-grade channel sample results from underground workings at its Sierra Mojada project. In Durango, Riverside announced its intention to drill the El Capitan project during 2018. In Guanajuato, Vangold is to measure the underground stockpile (backfill) at its Pinguico mine. In Estado de Mexico Impact Silver updated on exploration on the Zacualpan district. In Hidalgo, Prospero released interesting results on the first drill campaign at the El Petate project. ON MINING, Seven companies: Torex Gold, Coeur Mining, Hecla Mining, Endeavour Silver, Capstone Mining, Alio Gold and Alamos presented preliminary Q4 and annual production results for 2017. Santacruz Silver announced the commencement of construction work to expand the mill capacity at Veta Grande, Zacatecas. ON FINANCING, Avino Silver is now formally on the TSX.  ON RESOURCES AND DEVELOPMENT, Southern Silver updated its resource estimate on Cerro Las Minitas in Durango to over 50 M Oz Ag, 400 M Lb Pb, 1,600 M Lb Zn. Leagold released the high-grade results of the last 15 holes of its 2017 infill and expansion drill program at the Bermejal underground deposit in Guerrero.

ON MEXICO ISSUES

  • The illegal blockade at El Limon-Guajes mine in Guerrero continues. Torex Gold informed that two communities, Nuevo Balsas and Valerio Trujano have publicly supported the company and have asked the state government to intervene to lift the illegal blockade. The company is using an alternate route to enter and inspect the facilities while a government sanctioned process for selecting the workers union by vote is underway with a meeting scheduled for January 30, 2018, at which time the parties are expected to agree to a timeline for a vote (vote that the blockading union is expected to try to delay).

ON EXPLORATION

  • Impact Silver Corp. updated on exploration work at the Santa Teresa target, located on the Royal mines of Zacualpan district in Estado de Mexico. Numerous north-south and northeast striking veins transect the Santa Teresa area, with 197 assays greater than 1 g/t Au and up to 114.5 g/t Au. Half of the veins have extremely low sulfide content. The presence of a feldspar porphyry is considered to enhance the prospectivity of the area.
  • Riverside Resources Corp. informed on its exploration plans for 2018, which include the reception of drill results from the Glor and Clemente projects in Sonora, the drilling of the El Capitan project in Durango and Cecilia in Sonora. New partnerships will be explored to advance the Tajitos, (Sonora), La Silla (Sinaloa), Thor (Sonora) and Ariel (Sonora) projects.
  • Vangold Mining Corp. is to star underground drilling at its Pinguico property in Guanajuato on January 15, 2018. The drilling is to focus on grade definition of the underground stockpile (backfill) which is thought to amount 500 K tonnes, to define grade and metallurgical properties. The phase 2 program is to target the Pinguico vein to depth and on strike.
