Excellon Increases Production to 500,763 Silver Equivalent Ounces in Q3 2017


Toronto, Ontario – October 16, 2017 – Excellon Resources Inc. (TSX:EXN; TSX:EXN.WT; OTC:EXLLF) (“Excellon” or the “Company”) is pleased to announce third quarter 2017 production results from the Platosa Mine in Durango, Mexico.

Q3 2017 Production Highlights

  • Material increase in production following the completion of the Optimization Plan, including:
    • Silver equivalent (“AgEq”) production of 500,763 ounces, up 73% from Q2 2017 and 96% from Q3 2016
    • Silver production of 226,173 ounces, up 41% from Q2 2017 and 47% from Q3 2016
    • Lead production of 1.6 million pounds, up 86% from Q2 2017 and 78% from Q3 2016
    • Zinc production of 2.2 million pounds, up 95% from Q2 2017 and 86% from Q3 2016
  • Production rates averaging 200 tonnes per day (tpd) vs. 125 tpd in Q2 2017
  • Production headings accessed four mantos by the end of the quarter, including the high-grade 623 Manto, with further increases in production planned through the remainder of the year

“The turnaround in production at Platosa was clearly evident during the third quarter, with significantly improved tonnage-per-day, grades and costs,” stated Brendan Cahill, President and Chief Executive Officer.  “All-in sustaining cost decreased during the quarter to approximately $11-$13 per payable silver ounce.  We are now well positioned to continue ramping up production from four mantos through the fourth quarter and to realize a further decrease in AISC and increase in cash flow.”



TORONTO, Oct. 16, 2017 /PRNewswire/ – Sierra Metals Inc. (TSX: SMT) (NYSE AMERICAN: SMTS) (BVL: SMT) (“Sierra Metals” or “the Company”) is pleased to report third quarter 2017 production results featuring the highest quarter of throughput and second highest quarter of metal production to date from the Yauricocha Mine.

Results are from Sierra Metals’ three underground mines in Latin America: the Yauricocha polymetallic Mine in Peru and the Bolivar copper and Cusi silver Mines in Mexico.

Third Quarter 2017 Production Highlights

  • Silver equivalent production of 2.7 million ounces; an 8% decrease from Q3 2016
  • Copper equivalent production of 23.5 million pounds; an 8% decrease from Q3 2016
  • Total tonnes processed of 504,751; a 6% decrease from Q3 2016
  • Increase of 3% in silver equivalent production and 13% increase in throughput at Yauricocha during Q3 2017 vs Q3 2016

During the third quarter of 2017, consolidated metal production decreased 8% compared to Q3 2016. The decrease in metal production was due to lower production in Mexico which was partially offset by record throughput in Peru. The temporary decline in production in Mexico was mainly due to the implementation of a new plan to improve operational performance and produce profitable silver ounces at Cusi and improve efficiencies at our Bolivar copper mine. Like the successful program at Yauricocha in Peru, the Company has engaged in an operation turnaround program in Mexico to modernize operations, improve production and lower costs. We expect to see the results from this program become more apparent in the latter part of 2017 and early 2018.



October 16th, 2017, Vancouver, BC, Canada –ALIX RESOURCES CORP. (“Alix” or the “Company”) (AIX-TSX:V) (37N–FRANKFURT) announces that Perth-based lithium processing technologist, Lithium Australia NL (ASX: LIT)(“LIT”) has moved to a 54% controlling stake in the Electra lithium project in northwest Mexico. The project comprises the Tecolote, Tule, and Agua Fria concessions and is currently the subject of a farm-in and joint venture between Alix and LIT. LIT has the right under the JV terms to earn an ultimate 65% holding in Electra. Lithium Australia moved to the majority 54% ownership on completion of a recent drilling program.

This generated confirmation of a new 2.5 km-long, 25-50 m-thick mineralized zone lying on the western flank of the Agua Fria concession in what the JV partners described as the project’s best discovery yet.

  • Primero Mining Inc. acknowledged having received US$4.6 M in VAT refunds from the Mexican authorities in two installments over July and August, and is working closely with the SAT to recover in due time the outstanding US$32 M.


  • Azure Minerals Ltd. plans to start a 100 diamond hole, 5,000 m drill program at its Oposura property in Sonora during October, once the permits have been received. “Drilling by previous explorers of 85 surface holes tested the mineralised zone over an area of approximately 1,400m (east-west) x 400m (north-south) (see Figure 1). Early drilling by Azure will twin some of these historical holes to assess whether they can be used in defining the deposit and estimating the mineral resource”. With all the historical and recent work compiled Azure has derived an exploration target of 2.5 M tonnes @ 10% – 12% Zn+Pb.
  • Prospero Silver Corp. has received from SEMARNAT the permit to drill the Petate property in Hidalgo. Drilling is to start on September 17th, 2017, with 12 holes to test four targets: Apartadero SE, Apartadero Central, Tajo and Petate #3. “High-level epithermal alteration is exposed over a 5×4 km area with highly anomalous gold and silver hosted in extensive outcrops and float of steep to strata-bound jasperoid.”
  • Radius Gold Inc. released high-grade channel sampling results from the recently optioned Amalia property in Chihuahua. At the Campamento zone, where a 150 m by 300 m zone of intense silicification, brecciation and stockwork veining has been mapped, results include 62 m @ 0.43 g/t Au, 98 g/t Ag; 14 m @ 1.47 g/t Au, 167 g/t Ag; including 7 m @ 2.37 g/t Au, 239 g/t Ag.

  • San Marco Resources Inc. is readjusting its exploration strategy to accommodate an evolving geologic model on its Chunibas project in Sonora. The discovery of breccias in the recent core drilling program led to re-mapping and re-logging of the core, and the generation of a larger porphyry related breccia gold model with over printing epithermal quartz-carbonate veining. The surface mineralized footprint is 3 km x 1.5, and still open. The gold mineralization occurs disseminated and vein controlled. The re-logging of the core highlighted an 88 m breccia interval @ 0.37 g/t Au, and several drill holes present magnetite bearing potassic alteration associated with elevated gold grades. To test the property under the new model a magnetic survey is to be undertaken, along with the extension of some soil lines and deeper drill holes.


  • Argonaut Gold Inc. announced the first pour of gold at San Agustin, Durango, as scheduled. Impressive is the claim by the company of having had no lost time accidents during the 10 months construction period.
  • Primero Mining Corp. informed that the expected ramp-up production following successful negotiations with unionized workers has been significantly delayed due to persistent issues with underground equipment reliability, which has impacted development rates and stoping activities. As a result the production guidance has been lowered to 75 K to 85 K Oz AuEq at total cash costs of between $800 and $900 per AuEq Oz and all-in sustaining cost (AISC) of $1,050 to $1,150 per Au Oz.


  • Telson Resources Inc. has entered into a loan facility and offtake agreements with Trafigura Mexico, S.A. de C.V., to sell 100% of the lead and zinc concentrate produced at its Campo Morado mine in Guerrero.

The loan facility matures on September 2010 and bears interest at rate equal to LIBOR (3M) plus 5%.
  • McEwen Mining Inc. has entered into an agreement on a bought deal basis under which up to 9 M shares are to be purchased, for gross proceeds of $46.6 M, before deducting underwriting commissions and estimated offering expenses. If all the associated warrants are exercised before the two year expiration date aggregate proceeds are to reach US$74 M.  (El Gallo, Sinaloa).
  • Alamos Gold Inc. has secured amendments to its existing undrawn revolving credit facility, including an increase of the facility from US$150 M to US$400 M on more favourable terms (Mulatos, La Yaqui; Sonora).


  • Americas Silver Corp. released an updated mineral reserve and resource estimate for its Cosalá operations in Sinaloa. Proven and probable mineral reserves stand at 4.0 M tonnes @ 100 g/t Ag, 0.02% Cu, 1.6% Pb, 3.9% Zn; Measures and indicated resources include 8.0 M tonnes @ 128 g/t Ag, 0.24% Cu, 0.5% Pb, 1.2% Zn; Inferred mineral resources include 4.1 M tonnes @ 147 g/t Ag, 0.33% Cu, 0.6% Pb, 1.0% Zn.

A 240 m step-out drill hole intercepted 3.6 m @ 11.6 g/t Au. These results confirm the potential for extending the current resource, already defined in an area of 250 m x 150 m. “The Sub-Sill area is located between the El Limon and El Limon Sur ore deposits and under the El Limon Sill. The Sub-Sill area occurs in the Mesozoic carbonate-rich Morelos Platform, which has been intruded by Paleocene granodiorite stocks, sills and dikes. Skarn-hosted gold mineralization is developed along the contacts of the intrusive rocks and the enclosing carbonate-rich sedimentary rocks”.
  • Argonaut Gold Inc. provided updated pit-constrained mineral resource estimates for its El Castillo and La Colorada mines in Durango and Sonora respectively. At El Castillo measured and indicated resources stand at 63.97 M tonnes @ 0.36 g/t Au, and inferred resources at 1.57 M tonnes @ 0.36 g/t Au, for contained 751 K Oz Au and 18 K Oz Au respectively.
