TECHNICAL MEMORANDUM

Pinto Valley Unit Compliance

INTRODUCTION At the request of Capstone Mining Corp., AJAX Ltd (AJAX) has updated the Conceptual Groundwater Elevation Map and Cross Sections for 2015. The field work was completed in June 2015. This study fulfills the requirements of Compliance Item 12A of Aquifer Protection Program (APP) permit No. P-100329 as stated in the 2006 Groundwater Assessment Work Plan for the Pinto Valley Unit (PVU) to develop an updated conceptual groundwater elevation map for PVU. The study is intended to accomplish two tasks identified in the 2006 work plan: to demonstrate that the open pit is a hydraulic sink and to verify the adequacy of APP Point of Compliance monitoring well locations to monitor groundwater quality at the Pinto Valley Unit. The scope of the study includes collecting water levels at wells across the site, plotting conceptual groundwater elevation contours and constructing hydrogeologic cross sections in the open pit area. GROUNDWATER ELEVATION DATA AJAX checked water levels in 50 wells across the Pinto Valley mine site. Water level measurements were taken from across the site within a 3 day period from June 24th through June 26th. Depths-to-water measurements were collected with Durham Geo Slope Indicator 500 feet and 1000 feet Water Level Indicators. The water level measurements were recorded on field data sheets. If wells were dry or inaccessible that was also recorded. Water depths were converted to groundwater elevations by subtracting the depth to water from the surveyed measuring point elevation. In instances where surveyed well collar coordinates were not available, the well was located on a topographic map and an approximate elevation was interpolated from topographic contours.

The water elevations of the Pit Lakes were provided by PVM staff. The pit lake elevations were measured on June 23, 2015. The elevation of the northwest pond was 2,856.6 ft amsl. The elevation of the south pond was 3,000.2 ft amsl. The potentiometric surface was created in the SURFER software package using measured water levels. SURFER has several mathematical algorithms available for gridding and contouring datasets. All of these algorithms were tested with the 2015 water level observations to determine which best fit the data. Both the pit area potentiometric surface and the No. 4 Tailings area potentiometric surface were created using a Kriging algorithm. The resulting contours were drawn on an AutoCAD base map of the Pinto Valley Unit. Groundwater contours were adjusted to honor the observed elevations from surface water bodies and surveyed wells, where possible. Contours were not extrapolated outside the limits of the monitoring well data. Some wells showed considerably different water levels than nearby wells screened at different depths. This may be a result of the vertical component of groundwater flow being reflected in wells of different depths with different screened intervals and the complex structural geology of the Pinto Valley site. In some cases the data from these wells were not used to contour the potentiometric surface. In cases where there were multiple pressure transducers in a single well the shallowest transducer reading was used to construct the potentiometric surface. Levels from pumping wells were not used to contour the potentiometric surface. REVIEW OF WELL STATUS In the course of the eight years that PVM has performed annual monitoring, several wells have been damaged, destroyed, gone dry or otherwise been made inaccessible for monitoring. At the same time, new wells have been drilled and added to the monitoring list. The current Pinto Valley Mine APP lists 47 wells to be used for pit containment monitoring. As of June 2015 only 32 of these wells could be checked for water level. Table 1 lists the wells included in the APP and the current status of each one. Table 3 lists all wells that have been used since 2007 to construct the potentiometric surface and shows the years that they were measured. Table 3 also gives construction detail for these wells. As mining has progressed to the east and northeast many wells and piezometers in that area have been lost. The extent of the hydraulic sink in this area cannot be fully defined without additional monitoring points. AJAX will evaluate adding additional wells to the monitoring list in this area. Possible options include existing wells not currently being checked, new wells being drilled for geotechnical and hydrogeological investigations, and new wells drilled specifically for this monitoring program. ANALYSIS OF POTENTIOMETRIC SURFACE AND FLOW DIRECTION The results of the 2015 groundwater level measurements are presented in Table 2, below. The conceptual potentiometric surface interpolated from these measurements is presented on the attached Conceptual Groundwater Elevation Map, Drawing 1, and Conceptual Hydrogeologic Cross-Sections, Drawing 2.

Groundwater flow at the site generally follows topography. Groundwater in the vicinity of the open pit flows toward the pit lake from all directions, indicating the open pit is a hydraulic sink. Water that is not captured by the open pit sink generally flows west or northwest toward Pinto Creek as seen on Drawing 1. This is the same general groundwater flow pattern that was shown on previous potentiometric surface and groundwater elevation maps. Groundwater elevations changes from 2014 to 2015 were generally small, with only five wells showing water level changes of more than 10 feet. Well West 39 dropped 33.05 feet, well GT-MW-6 rose by 11.07 feet, well West 33 rose by 21.81 feet, well MW-04-15 rose by 40.28 feet, and well Shopsite 2 rose by 61.9 feet. The water level in well Shopsite 1 also rose. The well had a depth to water of 10.8 feet in 2014 and in 2015 it was artesian and flowing out of the well casing at ground level. Well APP-6 has been artesian in past years and the well head is configured for a pressure measurement rather than a manual measurement. This well was not artesian in 2015 and could not be measured. All water level changes are shown on Table 3.
