G MINING VENTURES ANNOUNCES
10,000 METER EXPLORATION AND DRILLING PROGRAM AND
PROVIDES OVERVIEW OF TOCANTINZINHO DEPOSIT
o Inaugural 10,000 meter drilling program to commence shortly
o Limited drilling to date, with only 82,805 meters (296 drill holes) from 2004-2015
o Focus on optimizing mine plan, de-risking initial years of production, and exploration at depth
o 1 diamond rig and 1 RC rig to be mobilized on site by mid-November
o GMIN also provides geological overview of deposit and historical drilling campaigns to date
G Mining Ventures Corp. (“ GMIN” or the “Corporation”) is pleased to announce an exploration and drilling
program (the “ Program”) at its recently acquired Tocantinzinho Gold project located in Para State, Brazil
(“Tocantinzinho” or the “Project”). The Program will total 10,000 meters and be focused on (i) de-risking the
pre-production period and (ii) testing for extensions to the known mineralization below t he pit in the
directions that remain open . Additionally, GMIN is pleased to provide a geological overview of the
Tocantinzinho deposit and of the historical drilling campaigns completed from 2004 through 2015.
Louis-Pierre Gignac, President & CEO of GMIN, commented: “Tocantinzinho is a homogenous orebody with
excellent grade continuity, and we are excited to launch our inaugural drilling program. With an existing gold
reserve of 1.8 million ounces , o nly 82,805 meters in 296 drill holes were completed inside the broader
tenement, in various phases between 2004 and 2015. The primary objective of the Program is to optimize
mine planning and de -risk mine performance during the initial years of production . With the deposit open
at depth and down p lunge, t he Program will also include exploration diamond drilling focused on
mineralization below the pit. The Program is to commence this month and continue into 2022.”
Pre-Production Drilling Campaign
7,000 meters of diamond and reverse circulation drilling will be targeting mineralization planned to be mined
during the early years of production. This campaign is intended to significantly de-risk mine performance,
particularly in the initial years of production. The objectives are to:
• Mitigate ore dilution by providing better definition of ore and waste boundaries;
• Optimize mine scheduling in the first 2 years of operation by populating areas with a low er drilling
density near surface (see Figure 1);
• Increase confidence in the quantity of ore mined and milled during ramp -up from a project financing
perspective; and
• Expand and validate the artisanal tailings by i mproving the sampling coverage in the area above the
pit and near the future infrastructure footprint.

Exploration Drilling Campaign
3,000 meters of diamond drilling will be targeting mineralization at depth down plunge to the northeast and
southeast of the currently known mineralization . The campaign is intended to test for extensions to the
known mineralization below the pit in the directions that remain open. The deposit is weakly tested at depths
beyond 350 meters, as focus by prior operator shifted to permitting after the mineral resource exceeded
2.0 million gold ounces . The deepest drill hole reaches 490 meters from surface, which is only 150 meters
below the current pit design (see Figure 2).
GMIN will follow up on drill holes from previous campaigns that rem ain open, such as TOC 09-121,
TOC 09-139 and TOC 09-152 (see Figure 2), which show higher -grade mineralization at the northwestern
and southeastern ends of the pit. This first phase of exploration drilling is aiming at better understanding the
attitude and spatial continuity of the high -grade interval in TOC 09-139, and potentially demonstrating
continuity of gold grades with TOC 09 -152. Partially tested mineralized intervals at the southeastern
extremity of the pit also provide good exploration opportuniti es and will be tested in the current program
(see Figure 2).
Details of the significant intervals at the base of the pit are presented below.

Overview and Background of Tocantinzinho Gold Deposit
Mineralization and Deposit Type
Tocantinzinho is a granite -hosted gold deposit, with several features typical of intrusion -related gold
systems, such as gold-bearing magmatic-hydrothermal textures and specific alteration assemblages such as
phyllic alteration. Its genesis is a source of debate as it also shares some features of Porphyry -style gold
deposits. Mineralization is mainly hosted in sub -parallel or anastomosing sheeted veins and veinlets
(chlorite-quartz-pyrite) in multiple directions.
The deposit is located within an intrusive suite, bounded and controlled by a major regional northwestern -
trending structure. In the center of the deposit lies an andesitic body, mostly barren, and often marks a
contact with mineralization . The Fort Knox g old mine, located in Alaska, USA, and currently operated by
Kinross Gold Corporation is an example of a deposit classified as an intrusion-related gold deposit and shares
some similarities with Tocantinzinho, such as gold-bearing sheeted veins, granite-hosted, Au>Ag and timing
of mineralization within the intrusion.
The deposit is sub -vertical, southeast trending with excellent grade continuity and consistency (see
Figure 3). Its continuity has been demonstrated by diamond drilling over approximately 900 meters in strike-
length, with widths up to 140 -200 meters and vertical extents up to 360 meters. While the lateral extents
have been tested by diamond drilling (see Figure 2), the main exploration upside is at depth where
mineralization remains open (current target of exploration drilling).
Historical Exploration and Drilling (2004-2015)
The exploration work completed to date includes geological mapping, channel and chip sampling, soil and
stream sediment geochemical surveys, a detailed topography survey, auger drilling, geophysical
investigations, limited reverse circulation drilling, and core drilling. Diamond drill holes are the principal
source of geological and grade data for Tocantinzinho deposit. However, the deposit does not have a high
level of historical drilling, with only 82,805 meters in 296 drill holes completed inside the broader tenement
between 2004 and 2015. The mineral resource estimate is directly supported by only 45,039 meters drilled
(55% of total) between 2004 and 2010. A summary of the historical drilling can be found below.

Mineral Resource and Reserve Estimate(1)
The current mineral resources estimate was generated on September 30, 2018 and is reported at a 0.30 g/t
Au cutoff grade. The estimate is supported by 3D geological and mineralization models , and the block size
used is 10 m east x 10 m north x 10 m high. Modelling consisted of grade interpolation by ordinary kriging
(OK) inside the mineralized shell.

The current mineral reserve estimate was generated on March 31, 2019 using a $1,200 per ounce gold price,
and is reported at a 0.365 g/t Au cutoff grade. GMIN is in the process of updating the current 2019 feasibility
study (Q1-22) and plans to optimize the mineral reserves and mine plan using a $1,400 per ounce gold price
that is more in line with the current market.

Tapajos Gold Province
Tocantinzinho is located in the large Tapaj ós Gold Province and is the largest known gold deposit in the
region. This region was the site of a major gold rush by artisanal miners from the late 1970s until the late
1990s which, according to the Brazilian Department of Mineral Production, had a total historical production
of between 20 and 30 million ounces of gold mainly from alluvial and saprolite sources.
The region is underexplored and hosts many gold deposits, such as Cuiù Cuiù ( Cabral Gold Inc.), Palito and
São Chico (Serabi Gold plc), and São Jorge (GoldMining Inc.). Deposit types vary from orogenic, disseminated
intrusion-related, porphyry -style and epithermal gold, as well as and po tentially porphyry Cu -Mo
mineralization. Deposit models evolve, leading towards the Tapajós Province being host of a major intrusive
system potentially generating various mineralization styles. Drill core observations and grade distributions
of the Tocantinzinho deposit also suggest a minor, late orogenic overprinting.
The association of gold with intrusions and higher -grade veining (orogenic gold) are at the heart of the
exploration model for future property-wide exploration drilling at Tocantinzinho. The numerous showings
and exploration upside in the property could potentially extend the current mine life with shallow, satellite
pits.

• Completion of Program (Q4-2021 through Q1-2022);
• Completion of project optimization studies and detailed engineering (Q4-21 through Q4-22);
• Completion of an updated 43-101 feasibility study (Q1-22);
• Commencement of onsite early works activities to support infrastructure and allow for rapid start of
construction activities (Q2-22 through Q3-22);
• Finalization of a comprehensive project finance facility to fund construction (H1-22); and
• Positive construction decision (H2-22).
Sampling and QAQC Disclosure
From May 2009 to December 2011, the sample preparation procedure at ALS involved weighing and drying
the sample before being crushed to 70% passing 2 millimeters. The sample was then riffle split to 1-kilogram
and pulverised to 85% passing 75 μm (200-mesh screen). The chemical analysis was performed at ALS Lima,
Peru, using 30 g sample for fire assay analysis (ALS Code Au-AA23). Select samples were also assayed for a
suite of trace elements using aqua -regia digestion and inductively coupled plasma -emission spectroscopy
(ICP-ES, ALS code ME-ICP41). A gravimetric finish was performed on fire assays returning more than 10 g/t
gold. Samples with visible gold were submitted to a metallic screen analysis under ALS protocols (ALS Code:
SCR21).
From July 2011 to January 2015 assays were performed at ACME Analytical Laboratory in Santiago, Chile.
Sample preparation was completed at ACME Analytical Laboratory in Itaituba, Brazil, where they were
crushed, split and pulverized until passing a 200 microns mesh. Gold was analyzed by fire assay with an
atomic absorption finish (ACME Code G6/FA430). Samples were also assayed for a suite of trace elements
using an aqua regia digestion and ICP-ES (ACME Code: D01/AQ300).
The QAQC program implemented by the previous operator involved the regular insertion of blanks, certified
standards and field duplicates. Blanks were used at the rate of one blank at each 40 samples, and a standard
was inserted every 10 samples . Field duplicates (one quarter of a core) were inserted at each 15th sample
or less. Coarse duplicates were submitted to the laboratory after return of the rejects of quartering. Results
from QAQC are monitored regularly.
