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

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 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.
  • Canuc Resources Corp. announced that several breccia targets have been exposed and sampled at its San Javier project in Sonora. Recent mapping has shown that the Carranza breccia could extend over an area roughly 400 m by 100 m. Select zones of this breccia have previously assayed 238 g/t Ag, 0.7 g/t Au over 11 m and 133 g/t Ag, 1.1 g/t Au over 6.5 m. Another breccia has been mapped on the Jazmin workings, with local high grade silver-gold results. Over 400 samples have been sent to the lab, assays are pending.
  • San Marco Resources Inc. released assay results from the newly discovered Cu-Ag mineralization on its Chunibas project in Sonora. The rock chip sampling followed the recognition of a geochemical anomaly in a soil survey, resulting in the discovery of isolated outcrops on otherwise covered terrain of presumably intermediate volcanic rocks strongly altered by an assemblage of epidote>chlorite>quartz>calcite>specularite. Results of 16 samples include 0.1%, 5.9%, 0.87%, 0.76%, 1.38%, 0.97% 1.8%, 0.41%, 3.72%, 0.25% Cu; 1, 51, 6, 8, 19, 4, 17, 4, 66, 4 g/t Ag.

The new zone comprises 350 m of old working, where 39 channel samples up to 2 m in length were collected, with 21 samples returning over 10% Zn and a peak value of 30.7% Zn; 21 samples over 100 g/t Ag and a peak value of 606 g/t Ag; nine samples over 5% Pb and a peak value of 17.6% Pb. “Our underground geological mapping shows a number of high angle structures up to 2 meters wide containing sulphide mineralization grading up to 1,300 grams per ton silver, 42% zinc, 18% lead, and 13% copper that appear to feed into the overlying oxide zone.”
  • Golden Goliath Resources Ltd. is to complete early in 2018 the drill targeting that was commenced on 2017 at its San Timoteo property in Chihuahua. Past work included a review of past data, including geology, geochemistry, structural geology, geophysics and drilling. Final drafting and final drill target selection remain to be completed. The company anticipates receiving a US$100 K option payment in 2018, and a final payment of US$2.8 M in November 2018. This would provide more than enough funding required for drilling without the need for any further dilution that a private placement would create.
  • Prospero Silver Corp. released drill results from its EL Petate prospect in Hidalgo. Highlights include 24.9 m @ 0.76 g/t Au, 22 g/t Ag; 12.6 m @ 0.51 g/t Au; 16.0 m @ 0.75 g/t Au, 2 g/t Ag; 3.9 m @ 1.18 g/t Au, 4 g/t Ag; 14.7 m @ 0.19 g/t Au, 2 g/t Ag; 1.1 m @ 10 g/t Ag, 1.5% Zn; 10.0 m @ 0.49 g/t Au, 24 g/t Ag; 3.2 m @ 1.96 g/t Au, 34 g/t Ag, 0.1% Zn; 19.3 m @ 0.32 g/t Au, 1 g/t Ag; 12.8 m @ 0.28 g/t Au, 6 g/t Ag.

IMPACT Silver provides Exploration Update on Santa Teresa gold target, Royal Mines of Zacualpan, Central Mexico

Impact Silver Corp

MPACT Silver Corp. (“IMPACT” or the “Company”) is pleased to provide an exploration update on a new and developing gold target within the Royal Mines of Zacualpan Silver District in central Mexico. Although work will be continuing on the silver-gold veins that have provided five centuries of historical production at the Zacualpan District, the work at Santa Teresa represents a new initiative for IMPACT’s exploration team to explore different sorts of mine making targets.

Summary
As a result of technical interpretation and additional field work, a new, possible bulk tonnage, gold target named Santa Teresa is being advanced by the IMPACT exploration team. Channel, chip and grab samples of bedrock have returned grades ranging up to 114.5 g/t gold, with 17 samples having more than 10 g/t gold and 197 greater than 1 g/t gold. Additional rock sampling and geological mapping has been initiated to designate drill targets.

Santa Teresa is located in the Valle de Oro sub-district of dominantly gold veins located four kilometers southwest of IMPACT’s producing Guadalupe mill and immediately to the south of IMPACT’s past producing Nochebuena (silver) and Carlos Pacheco (gold) mines. To the northeast is the large Coronas mine, one of the oldest and better known past producers of the Zacualpan district.
