Sandspring Resources (SSP-V) Sona Hill is a potential high-grade satellite gold deposit located 5km southeast from the 6.9 million ounce Toroparu Gold Deposit
Nov 3rd 2016 - NR
Sandspring Resources is pleased to announce initial results from its 2016 Core Drill Resource Definition Program (the "2016 Program") on the Sona Hill Prospect.
The Company has received assay results from the first 20 core holes (2,776 meters) drilled within the northern half of the Sona Hill prospect. Highlights of the drill results received to date include 30.4 m of 3.56 g/t gold from 64.5 to 95 m drill depth, including 9.4 m of 9.85 g/t gold from 73.6 to 83 m in Sona Hill Drill Hole (SOD) 058; 6 m of 5.91 g/t gold from 44.0 to 50.0 m drill depth, including 1.5 m of 14.1 g/t gold from 48.5 to 50 m in SOD0057; and 8.6 m of 4.05 g/t gold from 76.6 to 85.2 m drill depth in SOD046 are presented in Table 1.
Sona Hill is a potential high-grade satellite gold deposit located 5km southeast from the 6.9 million ounce Toroparu Gold Deposit ("Toroparu")1 (see Exhibit 1 Location Map). Drilling continues to support Management's belief that the Sona Hill anomaly hosts higher-grade, shallow mineralization that could complement the existing Toroparu and SE Zone Satellite deposits and improve project economics.
Hard rock mineralization was discovered at Sona Hill in 2012 during exploration of the cluster of ten gold features surrounding Toroparu. A 3,700-meter drill program in 2015 over an area of 800 m x 200 m intercepted high-grade mineralization within the hanging wall of a north-south oriented low angle shear structure, demonstrating the potential for a high-grade satellite gold deposit (see Sandspring press release dated February 3, 2016).

A complete list of gold drill intercepts are attached as Exhibit 1.
* The width as defined in Table 1 and the complete list of drill intercepts accompanying this release are the length of core and not the true width of mineralization as the true width of mineralization cannot be determined with the data and information available at this stage of the drill program.
To further support the continuity of mineralization between existing drill holes, Sandspring is completing a 7,000-meter infill drilling program in 75 diamond drill holes on 50m x 50m spacing. This drill density is designed to allow the Company to model and estimate a resource for the Sona Hill anomaly that can be incorporated into the mine plan for Toroparu.
Rich Munson, CEO states: "The drill results of this campaign confirm last year's intercepts and are very encouraging. Sona Hill is a "gold only" deposit with high-grade shallow mineralization. We are hopeful that mineralization at Sona Hill could be fed into the Toroparu processing plant in the early mine years, expediting payback and further bolstering the project's economics. "The success to date at Sona Hill also underscores the potential for further resource growth in the Toroparu district. Sona Hill is just one of ten high-priority gold features surrounding the Toroparu deposit, each of which has the potential to bring additional resources to the project."
The reported holes, SOD042-SOD061, represent a total of 2,776 meters of diamond core drilling (drilled July to August 2016) within the Sona Hill Area shown below.

Drill core logging indicates high to medium grade gold-pyrite mineralization is carried by sets of late staged tourmaline-feldspar bearing quartz veins, surrounded by strong hydrothermal bleaching and alteration. The veins form a network within intrusives of intermediate composition above an intensely altered low angle shearzone.
The Sona Hill mineralized system remains open at depth and along strike, and the Sona Hill drilling results underline the potential to develop additional resources within the 20 km by 7 km regional hydrothermal alteration halo surrounding Toroparu. Concurrent with the drill program, the Company is also conducting a soil geochemistry and IP geophysical survey west of the Sona Hill prospect, with the objective of identifying new zones of gold mineralization and finding the geological link with the main Toroparu area.
Otomung Concession Exploration
Further geochemical investigation is also ongoing in the prospective Otomung Concession, northwest of Toroparu (please see Location Map above), where last year's regional geochemical survey indicated anomalous zones located within or close to a feature interpreted as a granitoid intrusion, which indicates a geological setting like Toroparu. Infill sampling on a 100m x 50m grid over several anomalous features identified during the 2015 regional sampling program within the Otomung area is underway, with results expected in early 2017.
Analytical testing and reporting of quantitative assays for the results reported in this press release was performed independently by Bureau Veritas Mineral Laboratories Vancouver, Canada. Bureau Veritas Commodities Canada Ltd. is an ISO9001: 2008 accredited laboratory. A system of blanks, standards and duplicates were added to the Toroparu sample stream by the Company to verify accuracy and precision of assay results, supplementing a variety of internal quality assurance/quality control ("QA/QC") tests performed by Bureau Veritas Mineral Laboratories.

Quality Assurance / Quality Control
The drill program and sampling protocol is managed by Sandspring under the supervision of Lucas W. Claessens, P.Geo. and Pascal Van Osta, P.Geo. The diamond drill holes are drilled at HQ and NQ sizes and core recovery to date has averaged 94%. Half core is cut by rock saw and is generally sampled using 1.5 m meter intervals. Analytical testing and reporting of quantitative assays for the results reported in this press release was performed independently by Bureau Veritas Mineral Laboratories in Vancouver, Canada. Bureau Veritas Commodities Canada Ltd. is an ISO9001: 2008 accredited laboratory. Gold analyses reported in this release were performed by standard fire assay (FA450) using a 50-gram charge with atomic absorption finish and a gravimetric finish for assays greater than 10 grams per tonne. Samples from the geochemical survey were submitted for analysis of ICP 37 elements (including gold) AQ252 30 gram (Aqua Regia digestion - Ultratrace ICP-MS analyses). A system of blanks, standards and duplicates were added by the Company to the sample streams to verify accuracy and precision of assay results, supplementing a variety of internal QA/QC tests performed by Bureau Veritas Mineral Laboratories. The half core samples were securely transported by Sandspring personnel from the project site to the Bureau Veritas sample preparation facility in Georgetown, Guyana.
