Gold79 Outlines a Significant Exploration Target for Its Jefferson Canyon Gold-silver Project, Nevada
Gold79 Outlines a Significant Exploration
Target for Its Jefferson Canyon Gold-silver
Project, Nevada
Ottawa, Ontario--(Newsfile Corp. - January 26, 2021) - Gold79 Mines Ltd. (TSXV: AUU) ("Gold79" or
the "Company") is pleased to provide an update on its Jefferson Canyon Project located 7 km east from
the Round Mountain Gold Mine in Nevada USA.
Chairman & CEO Gary R. Thompson stated,
"Our work at Jefferson Canyon continues to highlight the
significant potential of this asset. Our recently identified 4 square kilometre gold-in-soil anomaly (see
press release, Jan. 12, 2021), along with compilation of historical data suggests that this is an
advanced exploration project. Our review of the historical data suggests there are geological
similarities to Round Mountain and that the small resource that may have already been identified is
just the beginning. We look forward to aggressively drilling Jefferson Canyon later this year, in an
effort to start proving up the multi-million-ounce gold exploration target we have identified."

As part of the Company's historical data compilation and review of the Jefferson Canyon project, an
exploration target has been defined. It is estimated that the exploration target has the potential for 40 to
200 million tonnes at 0.5 to 1 g/t AuEq with gold and silver. The internal mineralization block model used
to assist in providing an outline of the exploration target accounts for about one quarter of the gold-in-soil
anomaly area identified in the recently completed soil survey. Large areas of the gold-in-soil anomaly are
located to the east and northwest of the previously drilled areas and have not been drill tested.
Gold79 has generated an internal (non-compliant under CIM standards) block model of mineralization for
the Jefferson Canyon project (Figure 2). The block model was calculated based on 118 historical holes
totaling 18,106 metres. The Company does not currently have rock density measurements for Jefferson
Canyon core. Rock density of 2.3 grams per cubic centimetre was used given that Jefferson Canyon
shares many geological similarities with the neighboring Round Mountain deposit.

The goal of the internal resource estimate was to have a better understanding of the widespread gold-
silver mineralization at the property and identify mineralized domains suitable for future drilling and
resource definition. The table below summarizes the Jefferson Canyon mineral resource estimate
(internal, non-compliant) using various cut-offs.

Disclaimer: Figure 2 and Table 1 provided above represent a preliminary internal mineral
resource estimate for the Jefferson Canyon project that is only intended for informational
purposes. The resource is non-compliant under CIM NI-43-101 reporting standards and the
stated figures cannot be relied upon. Gold79 does not treat this as a current mineral resource
estimate and there are no assurances that it could be achieved.
Gold equivalent grade (AuEq) was calculated from estimated gold and silver grades in the block model
centroids using IDW2 (inverse distance weighting power 2), a recovery of 85% and average daily gold
and silver prices over the last 12 months of US$1,759/oz and US$19.50/oz respectively.
The formula used for calculating AuEq is as follows: AuEq
Revenue = ([IDW2 estimated Au g/t] *
[85%recovery] / [g to oz] * [Au $/oz]) + ([IDW2 estimated Ag g/t] * [85%recovery] / [g to oz] * [Ag $/oz]).

Ag mineralization.

Notes: (1) GJ drill holes were drilled by CR Exploration Company in 1984. JDD holes were drilled by
AMI Partners in 1981 and the TJ holes were drilled by Tuma Corporation in 1969-1970; (2)
Mineralized intervals are drilled lengths as true widths have not been determined at this time; and (3)
Gold equivalent grade (AuEq) was calculated using the following formula with average daily gold and
silver prices over the last 12 months of US $1,759/oz and US $19.50/oz respectively: AuEq = ((Au g/t *
Au $) + (Ag g/t * Ag $)) / Au $ per gram.

Next Steps
Gold79 is in the process of preparing its permit application to the US Forest Service for an extensive
drilling campaign at the Jefferson Canyon project. Gold79's permitting design will allow holes over the
entire soil anomaly as well as to confirm and validate historical drill results.
Geophysical data is currently
being reprocessed for QAQC and inversion modelling to further refine drill targets.
About the Jefferson Canyon Project
The Jefferson Canyon Project is located in south central Nevada and contains a large volcanic-hosted
epithermal Au-Ag system which is the same age as the nearby Round Mountain deposit/mine. Round
Mountain is a world-class low-sulfidation epithermal deposit that has produced 15Moz of gold to date
with additional reserves and resources. Both Round Mountain and Jefferson Canyon are hosted in felsic
ash-flow tuffs along the margins of calderas and both contain a strong northwest-trending structural
control to mineralization. Mineralization at Jefferson occurs in veins, vein-stockwork, disseminated and
stratiform replacement. Drill hole GJ81 at Jefferson Canyon returned 41.2m of 6.4 g/t Au and 402 g/t Ag
(
CR Exploration Company, 1985).
