TARON
The current Taron metallurgical experiment at UBC has produced promising results. It seems that eight (8) hours of leaching or longer is needed for a high Cs extraction. In addition, ~95% of Cs was precipitated as Cs alum with the addition of aluminum sulfate hydrate. The Company is not in position to disclose further data at this time as the results are a significantly better than the previous metallurgical experiment and the change is not fully understood. A new set of UBC leach tests will proceed.
The Company has reviewed the results from the 35 drill holes and the 10 drill holes with the highest grade Cs is planning an infill drill program around each of these higher grade holes with four (4) vertical reverse circulation drill holes (40 drill holes) at 75 metres depth totaling 3,000 metres. The objectives are to add additional tonnage to the showing and increase the overall grade. In addition the Company will in early February dispatch a prospecting crew and a possible ground magnetic survey to the east of Taron. There is evidence based on a property MMI geochem program that traversed the property in 2012 that the cesium mineralization is preset to the east to the Cambrian contact. This area is believed to be the location of the fault system that served as the conduit for the cesium mineralised epithermal fluids to surface permitting the fluids to flood and reside in the porous sediments that host the deposit. Drilling is scheduled for February 2018.
SARITA ESTE – DESIERTO II
The Sarita Este property borders Taca Taca to the west and Desierto II to the south. First Quantum (FM) holds title to Taca Taca which is a medium size Cu- Au-Mo porphyry system. The indicated resource is 1.612 billion tonnes. Mill feed should exceed 0.77% CuEq over the first 8 years.
As is widely known porphyry systems commonly occur in clusters. We believe Sarita Este and Desierto I and II have the basic alteration assemblages, elements and size to host one or more Cu-Au porphyry systems. We are particularly excited by Sarita Este as it adjoins Taca Taca’s western border, and it hosts very high gold grade values on surface. (See MAP ONE).
A rock geochemistry study Mark Fedikow Ph.D, in 2012 had the following observation and conclusions:
OBSERVATIONS AND CONCLUSIONS
There is overwhelming evidence in terms of patterns of variation for most elements analyzed in this survey to support the scenario of a buried zone of base metal mineralization in the southern survey area. Re-constructing this environment in light of the rock geochemical results however is somewhat difficult given that all elements from all six alteration facies subdivisions are enriched within the same approximate 3 km by 2 km area of the southern property. This area is bounded on the north by UTM northing 7283000 and by eastings 262500 to 262700.
Not all elements are enriched in the same samples and in many ways this is definitive of “zonation”. However, there is some difficulty with this model based on the consistent enrichments of most elements analyzed for this survey. The development of more or less concentric zones of mineralization-related alteration including their characteristic alteration mineral assemblages (sulphides, silicates, oxides, etc) around porphyry systems is well documented. Each of these alteration facies is developed at progressively greater distances from the mineralized zone. To see enrichments of the kind displayed by the TTM data would indicate that different levels of the concentric alteration haloes the system must have been exposed by erosion at surface in order to be sampled. An alternate explanation could be invoked whereby the system has been rotated and eroded in such a manner so as to expose multiple alteration facies in surface outcrop.
Regardless of the exact geological setting and attitude of the mineralized zone and attendant alteration facies the geochemical patterns depicted in this survey indicate the following:
- There is a multi-element anomaly developed over an approximate 3 km x 2 km area in the southern portion of the TTM (Sarita Este) property. Metal zonation is present within this 6 km2 zone.
- This anomaly is best explained by a buried base metal mineralized zone.
- The anomalous responses would necessarily be from rock samples collected from hanging wall rocks to this mineralization or to the roof pendant to a porphyry system.
- The irregular outcrop sampling pattern makes interpretation uncertain but not impossible.
- Based on copper responses the possibility exists that there are two buried base metal mineralized zones on the property.

SARITA ESTE (Con’t)
In 2006, the Company reported the assay results from 35 samples collected by CCD in 2006. 16 of the samples were greater than or were above 1.0 g/tn.
As published in a Cascadero news release dated August 13th 2012, 63 samples were taken from the same area but included the results for sub crop and two (2) high-sulphidation vertical zones in a trench.
This produced 11 samples that were greater than 10.0 g/tn; 10 samples that assayed greater than 30.0 g/tn; and 3 of those assayed over 100 g/tn and the highest single assay was 162.6 g/tn. These spectacular results were essentially ignored by the market. Historic exploration is all in the name of CCD. There have been three geochem surveys, 2006, 2012 and 2017. No drill holes or widespread trenching and no geophysical surveys. on his property to date and CCD acquired to prospect in 2005. A detailed mapping program was completed in 2017 and is available on the CCD website. www.Cascadero.com The 2017 program consists of property scale geochem and detailed mapping of the quartz-pyrite-gold-silver-copper veins and vein arrays to attain a an orientation that will focus the proposed 2,000 metre trenching program prior to locating drill holes. The program is expected to generate ~2,000 rock chip, rock grab and heavy mineral sieved samples for assay. The program is expected to take four weeks to complete.
SANTA ROSA
The program is scheduled to take five (5) weeks and generate ~2,000 samples. The objective is to use an excavator to strip the shallow overburden across selected alteration zones. This will provide data on the continuity of the mineral rich sulphide vein system that is present on the property over a strike length of seven (7) kilometres. A portable rock saw will be used to properly cut samples across the vein system. Samples will be collected for first stage mineralogy and metallurgy and mapping the vein system is a priority. Santa Rosa was acquired by CCD in 2006. There are no drill holes in the vein system and no mechanised trenching. A geophysical program was conducted in 1995 but is not available for review.
