(“Silver Spruce” or the “Company”) (TSX VENTURE:SSE)(FRANKFURT:S6Q) is pleased to provide the latest results from its ongoing reconnaissance and sampling program at its recently acquired Encino De Oro project near Chinipas, Chihuahua, in Mexico. The field crew was led by Leonard J. Karr, CPG, and a third party Qualified Person for Silver Spruce.

To date, a total of 42 chip channel and grab samples have been taken from outcrop, subcrop and float over an area of 3 square kilometres at the Encino De Oro project. Assays of these samples range from a less than detectable to as much as 8 grams per tonne (“g/t”) gold (Au), and 77 g/t silver (Ag), with anomalous values of copper (Cu), lead (Pb), zinc (Zn), arsenic (As) and antimony (Sb).

Prospero Silver Corp. (TSX.V: PSL) (“the Company” or “Prospero”) is pleased to announce that it has staked a high level epithermal vein system 85 kilometers northwest of Pachuca, Hidalgo State, Mexico; the closest town is Zimapan. Known as La Florida, the property covers 4,690 hectares.

The La Florida vein system is at least 3.5 kilometers long and strikes N70°W, dipping steeply to the SW. The property is located close to excellent infrastructure, and Hidalgo is one of the safest states in the Mexican Republic. The target area occurs within the western boundary of Sierra Madre Oriental where other proximal deposits such as Pachuca-Real del Monte, Zimapan, and La Negra are located.

Riverside Resources Inc. (“Riverside” or the “Company”) (TSX VENTURE:RRI / OTC PINK:RVSDF / FRANKFURT:R99), is pleased to report on the progress of the $250,000 USD partner-funded exploration program that is being conducted with Centerra Gold Inc. (“Centerra”) at the Glor Gold Project (the “Project”), located approximately 8 km west of Alamos Gold’s El Chanate Mine in Sonora, Mexico. Geologic mapping and soil sampling results have been very encouraging, having defined a gold-in-soil anomaly and zone of hydrothermally altered rocks that is more than 2 kilometres long. Induced polarization (IP) surveying has also returned positive results; a zone of anomalous chargeability that in extent closely matches the soil geochemistry anomaly has been defined by the survey. Ongoing channel sampling and soon to be initiated mechanical trenching are being carried out to further refine targets for drilling which is anticipated to commence in early 2017.
