Radius Gold Announces Initial Resource Estimate of 406,316 oz at 9.57 g/t Gold Equivalent at Holly

Highlights

• A maiden Inferred Mineral Resource has been estimated for the first target, La Peña vein at the Holly project, Guatemala.

• The high grade La Peña vein remains open to expansion along strike and importantly at depth,

where exceptionally high grade results have been returned.

• Multiple other drill targets remain un-tested at Holly with potential for new discoveries.

Table 1: Holly, Peña Vein Resource Estimate

(Effective date 7th June, 2022)

Notes:

1. Resources estimated using a 3.0 g/t Gold equivalent cut-off grade and a top cap grade of 100 g/t Gold and 2,000 g/t Silver and presented on a 100%-basis

2. Gold Equivalent Au(eq) values based on Au US$1800 and Ag US$22 using formula (Au g/t + (Ag g/t*0.01222))

1. Mineral Resources which are not Mineral Reserves have not demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, marketing, or other relevant issues. The mineral resources in this report were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum standards on mineral resources and reserves, definitions, and guidelines prepared by the CIM standing committee on reserve definitions and adopted by the CIM council. Notwithstanding, to meet the requirement that the reported Mineral Resources show "reasonable prospects for eventual economic extraction".

2. The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as an Indicated or Measured Mineral Resource. It is uncertain if further exploration will result in upgrading them to an Indicated or Measured Mineral Resource category.

3. Contained metal and tonnes figures in totals may differ due to rounding.

4. A technical report regarding the mineral resource estimation for the project will be filed by Volcanic on SEDAR within 45 days.

The Mineral Resource Estimate is underpinned by data from 21 diamond drillholes totalling 3707m of drilling. Drill spacing ranges between 20 and 100m. All sample data was composited to a 2D dataset (linear grade and true thickness values) prior to analysis and estimation. The sample database and the topographic survey were reviewed and validated by Bruce Smith, Ludving Monroy and Shawn Rastad prior to being supplied to John Arthur, an independent UK based Resource Consultant. Such review and validation help to support the reliability of the estimate. Geological domain modelling was completed by Bruce Smith and Dr John Arthur. Mineral Resource domain modelling, grade interpolation, Mineral Resource classification and reporting of the Mineral Resource statement, was performed by Dr John Arthur. Dr Arthur, Mr Smith, Mr Monroy and Mr Rastad are "qualified persons" within the meaning of National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). Block modelling was carried out using cell dimensions of 32mE by 32mN by 8 mRL and was coded to reflect the surface topography and mineralised zones. Density values were globally assigned into two zones, an upper zone between 50 to 100m from surface had an average density of 2.33t/m³ and below this an average density of 2.52t/m³ was applied. The Mineral Resource Estimate has been classified based on data density, data quality, confidence in the geological interpretation and confidence in the robustness of the grade interpolation.

The effective date of the Mineral Resource Estimate is June 7, 2022 and a Technical Report on the Holly property will be filed on Volcanic's website and SEDAR within 45 days of this news release.

Volcanic Founder, Director and CEO, Simon Ridgway, commented:

"The maiden Mineral Resource Estimate at the La Peña vein on the Holly property is an excellent start. I always believed from the exceptionally high grades found in outcrop at this property when Radius first made the discovery that it could host a significant gold deposit. With just thirty holes completed on the property since Volcanic signed the option deal with Radius, we have demonstrated that potential. The high grades, continuity and orientation indicate the deposit is appropriate for underground mining, and with the possibility of two mills operating within trucking distance of the deposit in the near future, the economic benefit for the communities in the area would be transformative.

Although it is at an early phase of exploration, we felt it important to show all stakeholders the value in the ground and what it can mean to the local communities. Their understanding, support and participation in advancing this project for the benefit of their communities and the shareholders is very important to Volcanic."

Radius Gold Inc. Director, CEO and project QP, Bruce Smith, commented:

"The high grade of the initial resource estimate and size with just a small number of drill holes demonstrates the potential of the La Peña vein system to grow quickly. This initial mineral resource estimate advanced our understanding of the project geology and we look forward to expanding La Peña at depth and along strike. Further at Holly project there remain multiple targets for drill testing and resource expansion, in particular the Alpha vein system and the intersection of Alpha and La Peña systems at depth. The data collected to date will guide the exploration strategy as well as the design for underground development at Holly."

Agenda in Guatemala

Volcanic will follow this resource calculation with the preparation of a preliminary economic analysis aimed to show that the high-grade La Peña vein deposit could be mined from underground, causing minimal surface disruption. It is anticipated that trucking of high-grade ore to a nearby mill could minimize on-site processing and other associated costs and impacts. The strategy is to calculate an approximate value of the deposit and potential income and be able to offer concrete benefits and much needed long term employment opportunities to the local communities. Radius expects the Holly project can grow significantly through exploration, but at this time it is important to clearly define the opportunity and potential value of the project to all stakeholders.

Technical Information

Bruce Smith, M.Sc. (Geology), a member of the Australian Institute of Geoscientists, is Radius's Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects. Mr. Smith has 28 years of mineral exploration experience and has prepared and approved the technical information contained in this news release.

Quality Assurance and Quality Control

Volcanic Gold follows industry standard procedures for diamond core drilling and analysis. Drilling is carried out using NQ and HQ size tooling. Drill core is cut in half using a rock saw with one-half of the core then taken as a sample for analysis. Sample intervals are generally 1m intervals, producing samples of between 2 to 9 kg. Half-core samples were initially processed at a Volcanic Gold preparation facility. The half core samples underwent primary crushing and split to produce a 250g sample under the supervision of a company geologist and qualified person. The split sample was then air shipped to certified ALS laboratories in Vancouver for further preparation and assay. All samples are fire assayed for Au and are analyzed for Ag and multi-elements using method code ICP following a four-acid digestion. Overlimits are analyzed using an appropriate method. Multi-element geochemical standards and blanks are routinely entered into the drill core sample stream to monitor laboratory performance. Quality control samples submitted were returned within acceptable limits.

Terms of Guatemala Radius Gold and Volcanic Gold Mines option

Pursuant to an option agreement signed in May 2020 with Radius, Volcanic can earn a 60% interest in the Holly and Banderas projects by spending the cumulative amount of US$7.0 million on exploration of the properties within 48 months from the date of the agreement. In accordance with the Option terms, Volcanic spent an initial US$1M on exploration within the 12 months of receiving the required drill permits, which expenditures included a minimum 3,000m of drilling on the properties.

Following the exercise of the Option, Volcanic will enter into a standard 60/40 Joint Venture in order to further develop the Properties. Volcanic has also been granted an exclusive right to evaluate all other property interests of Radius in Guatemala with a right to acquire an interest in any or all other such properties on reasonable terms.
