December 20, 2017, Vancouver, BC – Alio Gold Inc (TSX, NYSE MKT: ALO) (“Alio Gold” or the “Company”), is pleased to provide the final drill results from the 2,000 metre drill program to twin previous drill holes within the pre-feasibility pit for metallurgical test work samples at its Ana Paula project in Guerrero, Mexico.

Highlights

• Final drill results received from the 2,000m drill program for metallurgical sampling, confirm high-grade mineralization and lithology in the Mineral Resource Estimate (‘MRE’) dated May 16, 2017 as per the NI 43-101 Preliminary Feasibility Study
• Drill hole 17-13 intersected 112.0m (from 8.0m to 120.0m) of 3.85 g/t gold
• Drill hole 17-14 intersected 33.1m (from 116.9m to 150.0m) of 7.07 g/t gold
• Drill hole 17-15 intersected 54.6m (from 11.6m to 66.2m) of 7.19 g/t gold

“These final results of the drill program are again a reminder of the high-grade nature of the breccia mineralization within the proposed open pit at Ana Paula and give us further confidence in our existing block model,” said Greg McCunn, Chief Executive Officer. “We are excited to be turning our attention to testing the extension of the breccia zone below the proposed pre-feasibility study pit with a 6 hole, 4,000 metre program that is expected to begin in early January. This surface drill program will be undertaken in parallel to the construction of the underground decline which is being driven into the mineralized area to allow further drill testing from underground.”

Twin hole drilling program for metallurgical samples

This program which is now completed, was intended to provide sufficient material within the proposed open pit for metallurgical testing. Drill results for hole APM-17-04 and APM-17-05 were previously announced on October 24th, 2017 and drill hole APM-17-06 through APM-17-10 were previously announced on December 4th, 2017.

Note on true width calculation:
For the complex breccia and surrounding halo mineralization and in the monolithic breccia (MBX), the calculation of a true width is inappropriate since these units are not tabular. For the mineralization outside of these units (i.e. sediments (SED) and intrusive (INTRS)) the true width can be estimated since the mineralization is likely following the stratigraphy.

About Alio Gold

Alio Gold is a growth oriented gold mining company, focused on exploration, development and production in Mexico. Its principal assets include its 100%-owned and operating San Francisco Mine in Sonora, Mexico and its 100%-owned development stage Ana Paula Project in Guerrero, Mexico. Located within the highly prospective Guerrero Gold Belt on 56,000 hectares of underexplored land the Ana Paula Project is a high-grade, high margin project currently in the definitive feasibility stage. An underground decline to provide access for an exploration drill program has been initiated targeting the continuation of the high-grade gold mineralization below the proposed pit which has the potential to significantly enhance the robust economics of the project. The Company also has a portfolio of other exploration properties, all of which are located in Mexico.

Quality Assurance/Quality Control

Drill holes reported in this press release were drilled using PQ sized diamond drill bits. Company personal were located at the at the drill site. Contractors and employees of Alio Gold conducted all logging and sampling. The core was logged, marked up for sampling using standard lengths of approximately 1.5 meters. Samples were then collected by sawing a ¼ of the PQ core using a diamond saw with the remaining ¾ portion of the PQ core retained for metallurgical test work. The samples were catalogued and placed into sealed bags and securely stored at the site until it was shipped to sample preparation laboratory owned by ALS Chemex in Guadalajra, Mexico. The core was dried and crushed and pulverized to 85% passing 75 microns. The pulps were then shipped for assay to the ALS Chemex located in Vancouver, Canada. At that location, the samples were analysed for gold using fire assay with an atomic absorption finish (FA-AA) on a 50 gram charge. Samples returning over 10 grams per tonnes were re-assayed using a fire assay with a gravimetric finish. Samples were also analyzed for a suite of 35 elements using Aqua Regia Inductively coupled plasma atomic emission spectroscopy (ICP-AES). Over limits for silver, arsenic, zinc were re-assayed using a ore grade ICP-AES method. Quality control procedures included the systematic insertion of blanks, duplicates and sample standards into the sample stream. In addition, The Labs inserted their own quality control samples.

Cautionary Note to United States Investors
The Company is subject to the reporting requirements of the applicable Canadian securities laws, and as a result it reports its mineral reserves and resources according to Canadian standards. Canadian reporting requirements for disclosure of mineral properties are governed by NI 43-101. The definitions of NI 43-101 are adopted from those given by the Canadian Institute of Mining, Metallurgy and Petroleum. U.S. reporting requirements are governed by Industry Guide 7 (“Guide 7”) of the Securities and Exchange Commission (the “Commission”). These reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but embody different approaches and definitions.

The Company reports “resources” in accordance with NI 43-101. While the terms “Mineral Resource,” “Measured Mineral Resource,” “Indicated Mineral Resource” and “Inferred Mineral Resource” are recognized and required by Canadian regulations, they are not defined terms under standards of the Commission and generally, U.S. companies are not permitted to report resources in documents filed with the Commission. As such, certain information contained in this news release describing mineralization and resources under Canadian standards is not comparable to similar information published by United States companies subject to the reporting and disclosure requirements of the Commission. It cannot be assumed that all or any part of Measured or Indicated Resources will ever be converted into Mineral Reserves, an Inferred Mineral Resources has a lower level of confidence than an Indicated Mineral Resources and it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. Under Industry Guide 7, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. In addition the quantity and grade of reported Inferred resources are conceptual in nature, and are estimated based on limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. For these reasons, Inferred Mineral Resources has a lower level of confidence than Indicated Mineral Resources and it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of a feasibility study. In addition, the definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” under CIM standards differ in certain respects from the standards of the Commission.
