Core widths in CMLP-17-63 and CMLP-17-66 are considered to be true widths. Core widths in CMLP-17-65 and CMLP-17-68 are considered oblique to the mineralized zone. Gold assay composites were calculated using uncut assays.
A complete list of all intersections is available in Table 1 below along with a plan map and cross section.
Program Results
The drill program, which began in August 2016, is designed to validate the historic drilling database at the La Plata project. The drilling program is also intended to infill and expand known resources in the main La Mina VMS lenses leading to the completion of a National Instrument 43-101 resource estimate later this year.
Holes CMLP-17-65 and 68 are on the same section and were successful in extending mineralization on the eastern flank of the La Mina north zone lenses. Hole CMLP-17-63 was also completed on the same section and intersected mineralization just below the former mine underground workings.
Hole CMLP-17-66 was completed on the next section 30 m to the north and was successful in extending mineralization another 30 m toward the west. This hole intersected zinc-enriched sulphides with high grade values of 13.58% zinc over 10.22 m along with corresponding high gold and copper values.
Modelling of historic and current drill results by Toachi staff has delineated four discrete mineralized zones which define the La Mina North and La Mina South blocks. For a 3-D graphic of the wireframed zones, please visit our website at www.toachimining.com and see our latest presentation. To date, Toachi has completed 13,748 m of drilling on the La Plata project.
Nick Tintor, President and CEO, stated, "Toachi continues to generate exceptional drill results from the La Plata project which underscores the high grade and gold-rich nature of the VMS mineralization in this deposit."
Management believes the La Plata project, which is characterized by geology typical of major gold-rich VMS camps around the world, hosts excellent potential for the discovery of additional discrete VMS zones amongst the 14 exploration targets identified to date.
43-101 Resource Estimate
Work on a maiden 43-101 resource estimate study has begun and is being supervised by Brian Wolfe of International Resource Solutions PTY Ltd., of Perth, Australia. Mr. Wolfe has been to the La Plata project site and is working closely with Toachi's geological staff in preparing the resource estimate and technical report.
Toachi and its consultants anticipate delivery of a resource estimate sometime in September, one month later than previously planned.
Jonathan Goodman, Chairman, stated, "The completion of our maiden 43-101 resource estimate will be a milestone document for the La Plata project as our drilling is expected to materially enhance the historic estimates."
La Plata Deposit Geology
Gold-bearing sulphide mineralization at La Plata occurs as compositional banding composed of chalcopyrite, sphalerite and pyrite laminae with barite occurring as clasts and also as thin layers.
Base and precious metal mineralization at La Plata is interpreted to have formed as part of multiple volcanic episodes that created a stacked volcanic-exhalite hydrothermal sequence which is considered favorable for hosting multiple VMS lenses.
Examples of this exclusive group of gold-rich VMS camps include Noranda, Doyon-Bousquet-LaRonde and the Flin Flon camps in Canada.
Toachi's exploration staff has identified more than 14 discrete exploration targets across the property concessions which extend for more than 9 kilometres, attesting to the potential of this emerging district.
The La Plata Project
Toachi entered into an option agreement with a private Ecuadorean company to earn between a 60% to 75% interest in the La Plata gold-copper-silver-zinc VMS project, located 85 km south of Quito, Ecuador.
For complete terms of the transaction, please see our press release dated February 11, 2016 which is available on our website at www.toachimining.com or on www.sedar.com .
La Plata is a gold-rich volcanogenic massive sulphide deposit which was the subject of small scale mining from both an open pit and underground workings from 1975-1981.
From 1996 to 2000, Cambior Inc., a Canadian mining company, completed 8,628 metres of drilling and a preliminary resource estimate totaling 840,000 tonnes grading 4.8 grams gold per tonne, 4.1% copper, 54.4 grams silver per tonne and 0.7% lead and 4.2% zinc per tonne in 1999, according to a report completed by AMEC Foster Wheeler, a mining consulting firm, in March 2015.
Following a drill program by Cornerstone Capital Resources Inc., which included 5,933 metres of drilling from 2006-2007, a revised mineral resource estimate totaling 913,977 tonnes grading
8.01 grams gold per tonne, 88.3 grams silver per tonne, 5.01% copper, 6.71% zinc and 0.78% lead per tonne in the inferred category was completed.
The resource estimates described above are historical estimates as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects S.2.4 ("NI 43-101").
Toachi has not completed the work required to independently analyze and verify the results of the previous operators nor has a qualified person completed sufficient work to classify the estimates as current mineral resources or mineral reserves. With respect to the Cambior estimate, the Company is also not aware of what categories were used in the estimate. As a result, Toachi is not treating these estimates as current mineral resources or mineral reserves.
The Company believes these historic results provide an indication of the potential of the property and are relevant from an on-going exploration perspective.
QA/QC Sampling and Core Sampling Protocols
Before sampling, a centreline, representing bottom of hole (or a reference line when this is not known) is marked on the drill core. The core is cut and sampled, always sampling the right-hand side of the drill core. Samples are selected based on logged geological features, such as rock type, mineralization, alteration, veining etc. Sample length does not exceed 1.2 m nor is smaller than 20 cm. In areas of similar geological characteristics, sample length is, in general, 1 m.
A total of 10% of the samples submitted are certified blanks and standards and field duplicates with, as a minimum, one blank submitted at the beginning of each sample batch. Certified standards are submitted at an average of 6% of the samples submitted. Field duplicates are taken at a rate of 1 in 20 of the samples taken.
Drill hole analysis was completed by ALS Peru S.A. and MS Analytical in Canada.
For ALS, sample preparation was completed in Quito, and analysis by ALS Peru S.A. in Lima. The lab is accredited with International Standards ISO/IEC 17025:2005 and ISO 9001:2015.
All major ALS Geochemistry analytical laboratories are accredited to ISO/IEC 17025:2005 for specific analytical procedures.
For MSA, analysis was completed by MS Analytical in Canada with preparation performed by Ecuadorian partner, LAC y Asociados. Both LAC y Asociados and MSA are ISO 9001:2008 registered companies. MS Analytical also meets the requirements as outlined in ISO/IEC 17025.
