A hard boundary between the high and low grade zones was used in the base case model. As a sensitivity, a limited soft boundary was tested which allowed low grade zone composites to influence the estimation of the high grade zone within 5 to 10 m of the boundary. The limited soft boundary scenario resulted in up to 3% less tonnage, 1% lower grade for up to 3% fewer ounces. Overall, SRK considers this impact to be immaterial.

Sampling of the saprolite material poses a significant challenge due to the clay-like nature of the ore and the way in which it is stockpiled and fed to the plant (using dozers and backhoes that feed grizzlies installed over chutes which then deposit material onto feeders that drop saprolite on top of crushed ore on the SAG feed conveyor). These constraints prevent sampling on the SAG feed conveyor since the material is already mixed with crushed ore, and the stickiness of the material and inconsistent feed rates of saprolite make sampling at the conveyor feed chutes or off the conveyor feeders unviable solutions. It was therefore concluded that in order to accurately account for the gold coming from Saramacca, the material arriving at RGM would need to be weighed and sampled before being stockpiled. After discussions with several sampling system vendors, a relatively simple system consisting of an auger-type pipe sampling solution was selected. While it is not considered as accurate as a cross-belt or falling stream sampler, it was simpler and less prone to problems due to the sticky nature of the material.

The actuator and valve create a single unit – the control valve. Actuators perform different motion sequences, including linear, pivoting and rotating motions, and they are powered by pneumatic, hydraulic or electrical energy.

Sampling is supervised by an IAMGOLD-RGM geologist or technician at the drill site. FTE Forage drilling personnel collect the samples from the Metzke cyclone splitter, while IAMGOLD-RGM personnel are responsible for further handling of the samples including weighing, tagging, and logging using GemsLogger on a laptop or tablet. All further sample handling in preparation for shipment to Filab is done at Saramacca camp.

The metallurgical test program for the Feasibility Study started in January 22, 2018 under the supervision of IAMGOLD. The metallurgical test plan included both composite and variability samples. The material tested was collected from both the southeast and northwest areas of the pit and from the saddle area in between. The material also covers all rock types including duricrust, laterite, saprolite, transition, and fresh rock. The test plan aimed to determine the response of Saramacca material to the existing Rosebel flowsheet and to identify any possible flowsheet modifications required to optimize recovery.

Lime is added to the grinding circuit to increase the slurry pH to 10.5 which is the alkalinity set point for cyanidation. Sodium cyanide is added to the SAG feed chute and the first leach tanks to effect gold leaching. All tanks are sparged with low pressure air to ensure sufficient oxygen is available for the gold dissolution reaction.

SRK is satisfied that the Mineral Resources were estimated in conformity with the widely accepted CIM Estimation of Mineral Resource and Mineral Reserve Best Practices Guidelines (2003). The Mineral Resources may be affected by further infill and exploration drilling that may result in increases or decreases in subsequent Mineral Resource estimates. The Mineral Resources may also be affected by subsequent assessments of mining, environmental, processing, permitting, taxation, socio-economic, and other factors. The classified Mineral Resource estimate shown by weathering zone for the Saramacca gold project is presented in Table 14-19. The consolidated Mineral Resource Statement, including RGM, is presented in Table 14-1.

As an opportunity, additional test work is recommended to optimize metallurgical performances for each rock type. Additional tests would also help to identify problematic zones or lithologies within the deposit.

Figure 2. There’s a pressure drop between the upper portion of the loop, where the supply side of the load circuits connect, and the lower portion of the loop, where the return side of the load circuits connect.

For example, let’s say you’re away on vacation and you turn your heat off to save power. If the temperature were to dip below freezing and cause a pipe to burst, Iris moisture sensors could detect the leak and automatically tell the Smart Valve to shut off the water main. And that’s just the worst-case scenario. With the help of Iris temperature sensors, the valve could ostensibly be configured to shut off your water before the temp hit the freezing point — effectively preventing a pipe burst from happening in the first place.
