Thin Section Results
January 23, 2018
Cascadero (‘CCD or the Company”) is pleased to announce the results of a thin section study of twelve (12) rock grab samples taken from the Company’s Sarita Este gold prospect, 70% owned by the Company. Sarita Este is located in Salta province in northwestern Argentina in close proximity to First Quantum’s Taca Taca multi-billion tonne Cu-Mo-Au porphyry deposit.
The results of the study suggest that Sarita Este is a high-sulphidation gold bearing epithermal system. Additionally, the phases of alteration present in the host rocks at Sarita Este are consistent with a large hydrothermal system related to porphyry-type mineralization as the samples were collected over a 2 km by 5 km area. The presence of cubic clasts (after pyrite), iron oxides and malachite (after chalcopyrite?) in association with the late silicification indicates that the hydrothermal system matured sufficiently to produce sulphides and therefore the area has the potential to contain a mineralized porphyry-type magmatic system. This sequence of alteration events materially increases the size of the Sarita Este target.
Mr. Bill McWilliam CEO of Cascadero Copper states “we are extremely pleased with the results of this thin section study which are not only strongly positive regarding Sarita Este’s potential but extremely valuable to Cascadero as it further advances and explores this promising early stage gold prospect.
We are especially excited by the introduction of evidence regarding the mineral potential of Sarita Este’s suggested large-size underlying parent. This conclusion completely changes and upgrades the valuation metrics of the Company.”
The presence of iron oxides and malachite after chalcopyrite in association with the late silicification indicates that the hydrothermal system matured sufficiently to produce sulphides and therefore the area has the potential to contain a mineralised porphyry-type magmatic system.
Twelve (12) samples were sectioned. Eleven (11) of the samples are felsic volcanic rocks and the other is granite. The weakly altered medium grained granite is cut by a small quartz vein/breccia zone that exhibits alteration stronger than the surrounding wall rocks. The alteration to sericite is accompanied by both hematite and malachite (possibly after chalcopyrite).
In general, the three massive felsic volcanic rocks (flows?) are more intensely altered than the younger granite. The feldspars are altered to albite. The alteration includes weak propylitic (sericite-chlorite-epidote) alteration and weak to intense silicification.
The tuffaceous felsic volcanic rocks are more intensely altered than the massive rocks with plagioclase altered to albite and intense silicification with the addition of quartz.
The alteration ranges from weak propylitic (sericite-chlorite-epidote) to moderate propylitic (albite-sericite-chlorite-epidote-calcite) to phyllic/silicic and grading to argillic (clay-quartz-jarosite-alunite). The intense silicic alteration is manifest by the addition of quartz as a pervasive replacement, veinlets, stockworks or breccia. The late silicification is associated with cubic casts, limonite, goethite and malachite, which are probably remnants of weathered pyrite and/or chalcopyrite. Electrum (a gold-silver alloy) was tentatively identified in one of the quartz-rich areas.
The variation in alteration from less in the more massive rock to most intense in the more porous tuffaceous rocks is consistent with alteration caused by circulating hydrothermal fluids rather than in-situ alteration during cooling. Alteration that ranges from weakly propylitic to phyllic and argillic are typically found in shells surrounding porphyry style copper and copper-gold deposits. In addition, intense silicification with sulphide minerals and/or gold-silver commonly overprints the earlier alterations in mineralized systems.
The thin sections were prepared by Vancouver Petrographic Ltd. and are described in detailed report delivered to the Company in January 2018.
A “thin section” is a piece of rock or a mineral species specifically prepared to study its optical properties. Each sample is ground to a 0.03 millimetre thickness then polished and placed between two microscopic slides. The samples are then studied to identify resident minerals, determine their volumetric percentages and describe their textures. Petrographic studies are critical to understanding the origin of the rock in order to provide a geological understanding of the property.

Sarita Este Gold Project Update?First Phase Of 2017 Exploration
November 15, 2017
The Company is pleased to announce the results of Phase One of its Sarita Este program in the Puna region of Salta Province, Argentina.
The Sarita Este prospect is an untested gold bearing system that is believed to represent a high-sulphidation epithermal system peripheral to First Quantum’s Taca Taca copper-molybdenum-gold porphyry deposit located approximately six kilometres to the northeast. Of the 128 prospecting rock samples collected in the area since 2004, 87 (68%) are greater than 1 ppm gold and 36 (28%) are greater than 10 ppm gold. The gold bearing samples are from sheeted quartz veins within a broad area of recessively weathered limonitic, sericitic and clay altered volcaniclastics. The alteration system appears to be structurally controlled exhibiting a strike length of 1,200 metres in a NNW trending direction and 400 metres wide. Outcrop is limited by the recessive weathering and the prospect is open in all directions. The samples are selective grab samples, and the geochemical results are not necessarily representative of the mineralization hosted on the property.
The October 2017 program consisted of grid soil sampling, rock sampling detailed structural and geological mapping. A total of 646 soil samples were collected from the “C” horizon, and a total of 218 rocks samples were collected, including 46 one-metre channel samples from three (3) historic 2012 Cascadero trenches.
All samples were shipped to the Alex Stewart Argentina SA Lab in Mendoza for preparation and analysis of 42 elements by 4 acid digest and Ultratrace ICP-MS, and gold by fire assay AA. Currently, the QA/QC program consists of the insertion of duplicates and standards at the lab. A more rigorous QA/QC program of field blanks and standards will be implemented once drilling and trenching begins.
Alex Stewart Argentina SA is an ISO 9001 and ISO 14001 accredited analytical lab and is not a related party to Cascadero Copper Corp.
Phase Two trenching and systematic sampling of the Sarita Este zone will begin once results have been received and permitting is in place.
The Sarita Este property is an early stage exploration project on which no mineral resource has been identified nor has the economic viability or technical feasibility been established. The property has never been subject to a drill program.

taron exploration program

MAP ONE
TARON PROPERTY LOCATION
TARON EXPLORATION PROGRAM
The first program will consist of an HQ core hole program that will test the potential of the mineralized material adjacent to the eleven (11) best drill holes of the recently completed 2017 program. It is planned to complete four one-hundred metre vertical core holes around each higher-grade hole. A drill hole will be collared at 100 metres to the north, east, south and west around the eleven highest-grade 2017 drill holes for a total of 3,300 ? 4,000 metres. This is expected to augment the volume of Cesium mineralization present and provide the metrics to increase the Taron target deposit grade, size and develop a potential mineral resource.
The second program is a property-scale exploration program that will include detailed mapping, trenching, mineralogy, reconnaissance style drilling, and metallurgy to test for mineral leach kinetics.
Another objective is to determine the location(s) of the boundary fault zone and its related splays in the eastern part of the Taron property. This is based on the assumption that Taron mineralization may be associated with major crustal structures that define the eastern boundary of the Puna with the eastern boundary ranges of the Andes. The fault zone separating the basement strata represents a continental northerly trending suture zone that separates the rock assemblages of the ancient continent of Gondwanaland to the east from more exotic terranes to the west.
Company management believes this area may be the location and conduit for Taron style mineralization. This suture zone was likely established during a major orogenic event. This continental scale collision zone spans much of the south-central Andes, an event that occurred some 455 million years ago. This is very exciting for Cascadero to hold an interest in a small portion of a continental orogenic event that are known to create the geological setting for a variety of large-scale mineral deposits.
MAP TWO on the following page illustrates and identifies the Punco Zone that is 4,800 metres (4.8 kms) to the south east of the Taron Main and North Zones. The Punco zone was subject to prospecting and samples were taken from a backhoe pit. The host rocks are similar and the grade of the samples is similar to samples from Taron North and Main Zones. In 2010, the Company completed an MMI geochem program that extended the properties’ potential for Cesium mineralized material part of the way across the Taron showing towards the assumed continental suture as the MMI data showed a positive Cesium response.
MAP TWO
PLAN VIEW - TARON PROPERTY
The Taron target deposit consists of five (5) Contiguous Mineral Tenures, approximating 8,179 hectares (83 Units) in area. The Tenures are registered to Cascadero Minerals S.A. (CMSA), which is 100% owned by Cascadero Minerals Corporation (CMC), a Canadian Company, which is 70% owned by Cascadero Copper Corporation (CCD) and 30 % owned by Regberg Ltd. (RB). CMC operates as a 70% CCD and 30% RB joint venture.
NOTE: the Punco zone is situated on the Incamayo tenement which is 100% owned by CMC. The Incamayo property has excellent potential to host Copper-Gold-Silver-Tin-Tellurium mineralized material as these elements occur in historic drill holes.

Cesium Recovery From The Taron Deposit Demonstrated
November 7, 2017
The recovery of Cesium from a mineral sample from the Taron target deposit has been demonstrated. The mineral sample was obtained from the 2009 drill program (drill hole number TAR-09-5). A sub-sample was crushed and ground to a particle size of 100 microns (P80). The Cesium content of the sample was analyzed at 4761 ppm or 0.476%. A full analysis is shown in Table 1 below.
The metallurgical treatment of this sample was demonstrated at the University of British Columbia (UBC), Department of Materials Engineering, Vancouver, Canada.
Highlights included:
94.7 % extraction of Cesium after 4 hours of leaching at 90 C with 250 g/L H2SO4 and 20 % SolidsRecovery of 97.8 to 99.4% of the Cesium as a Cesium Aluminum Sulfate (Alum) precipitate after addition of aluminum sulfate and cooling to 4 C.Purification of the Cesium-containing alum using (1) re-dissolution and re-precipitation of alum by hot water leaching, cooling and filtration, (2) re-dissolution of purified alum by hot water leaching followed by removal of aluminum and sulfate by stepwise precipitation by addition of barium hydroxide. The result of this treatment was a high - purity Cesium hydroxide solution.Conversion of the Cesium hydroxide solution to Cesium formate solution by simple addition of formic acid.The co-precipitation of iron, arsenic and other species from the leachate using neutralization with limestone was demonstrated.
The overall procedure had three stages: leaching, crystal formation, crystal purification, and Cesium sulfate purification, and the corresponding recoveries of Cesium were 94.7%, 99.9%, and 96.1%, respectively. This gives a total of 90.9% Cesium recovery over the entire process assuming all wash solutions would be recycled with negligible Cesium losses.
The Company is funding ongoing study of Cesium recovery including (1) upgrading of the Taron mineral sample by mild scrubbing and screening, (2) acid leaching with reduced acid concentration, (3) alternative leaching process options. Following these studies, it is expected that the Company will commence a metallurgical pilot plant study to provide final engineering parameters for a feasibility study for Cesium recovery from the Taron target deposit

Mr. Bill McWilliam, Chairman, Cascadero Copper commented “This initial metallurgical program has conclusively demonstrated that high - quality Cesium formate Cesium Hydroxide solutions may be recovered from the Taron target deposit mineralization”. “Cesium formate is in high - demand in the oil and gas drilling sector as Cesium formate solution has a very - high density (2.30 g/cm3). Cesium formate also has several other important properties for drilling and completion of down hole operations. It is considered the premier product of alkaline brines and all other drilling fluids.”
“It is expected that the ongoing UBC metallurgical program will increase the efficiency of the process and decrease costs. In addition, I these metallurgical results may be an historic moment in geological deposit understanding, mineralogy, due to impressive persistence and excellence of the UBC metallurgical team. I understand that the recovery of Cesium from an epithermal sediment hosted polymetallic mineral source other than Pollucite, is a first.”
“I congratulate Cascadero’s staff, consultants, advisers and investors for their support and patience to the finish line.”
