MARGAUX RED CAPITAL INC. AND SIGMA LITHIUM RESOURCES INC. ANNOUNCE

FILING OF TECHNICAL REPORT FOR QUALIFYING PROPERTY AND PROVIDE AN

UPDATE ON THE PRIVATE PLACEMENT AND THE QUALIFYING TRANSACTION

Vancouver, British Columbia: March 28, 2018 – Margaux Red Capital Inc. (NEX-MXC.H)

(“Margaux”) and Sigma Lithium Resources Inc. (“Sigma”) are pleased to announce the filing of a

technical report (the “SGS Technical Report ”) on Sigma’s 100% owned past-producing lithium project

in Brazil (the “Project”), which includes a mineral resource estimate for the Xuxa pegmatite on the Grota

do Cirilo property of the Project. Margaux and Sigma also provide this update regarding the proposed

qualifying transaction as detailed in Margaux’s December 22, 2017 press release (the “Proposed

Transaction”) and Sigma’s private placement financing. Margaux advises that there has been no material

change to the information contained in its prior press release, other than the further information provided

in this press release.

Select Technical Information regarding the Qualifying Property

Sigma, through its wholly-owned subsidiary Sigma Mineração S.A., is focused on developing its 100%

owned past-producing project located in the Araçuaí and Itinga regions of the state of Minas Gerais,

Brazil. Sigma’s properties are comprised of 28 mineral rights. The Project has been evaluated as a

potential high grade, hard rock lithium mining project which hosts numerous prospective lithium bearing

pegmatites within its land package of over 18,800 hectares.

Based on the SGS Technical Report (with an effective date of January 29, 2018), completed by SGS

Canada Inc. in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral

Projects (“NI 43-101 ”) and approved for purposes of the Proposed Transaction by the TSX Venture

Exchange (the “TSXV”), the mineral resource estimate outlines approximately 12.9 million tonnes of

resource classified as Measured & Indicated at an average grade of 1.56% Li20. In addition the mineral

resource estimate outlines an additional approximate 600,000 tonnes of resource classified as Inferred at

an average grade of 1.47% Li20. The mineral resources outlined were reported using an open-pit mining

perspective.

The following is the summary mineral resource estimate for the Xuxa pegmatite which is located on the

Grota do Cirilo Property of the Project:

Cut Off Grade Category Tonnage* Average Grade

(Li2O%) (% Li2O)

0.5 Measured 8,502,000 1.57

0.5 Indicated 4,385,000 1.55

0.5 Measured+Indicated 12,887,000 1.56

0.5 Inferred 609,348 1.47

Notes: The mineral resource estimate has been conducted using the CIM Definitions Standards for

mineral resources in accordance with NI 43-101. Mineral resources, which are not mineral

reserves, do not have demonstrated economic viability. Inferred mineral resources are

exclusive of the Measured and Indicated resources.

A fixed density of 2.72 t/m3 was used to estimate the tonnage from block model volumes.

Resources are constrained by the the topography

In addition, as part of the SGS Technical Report, exploration work undertaken by Sigma, as well as

historical work at the Project, was analyzed and assessed for exploration potential based on available

drilling, channel samples, grab samples and surface mapping. This analysis identified the potential for

additional mineralization with estimated aggregate volumes ranging from 37 million tonnes to 57 million

tonnes of potential lithium bearing mineralization. The following tables summarize the exploration

potential outlined in the SGS Technical Report.

Private Placement

As previously disclosed, the pre-transaction financing is by way of a brokered private placement (the

“Private Placement”) of subscription receipts (“Subscription Receipts”) by Sigma through a syndicate

of agents being co-led by National Bank Financial Inc. and Cormark Securities Inc. and including

Canaccord Genuity Corp. (together, the “Agents”). The Private Placement is expected to close on or

about March 29, 2018, and is expected to provide adequate capital to further explore and develop the

Project (including the exploration and development expenditures detailed above).

Through the Private Placement Sigma has offered a maximum of 10,000,000 Subscription Receipts at a

subscription price of $2.00 per Subscription Receipt for aggregate gross proceeds of up to $20,000,000.

Applying the exchange ratio for the Proposed Transaction of 10.045125 Margaux common shares per

Sigma common share, the 10,000,000 Sigma common shares to be issued on conversion of the

Subscription Receipts will be exchanged for 100,451,250 Margaux common shares (resulting in an

effective subscription price of $0.1991 per Margaux common share). Each Subscription Receipt will

entitle the holder, at no extra cost, to one common share of Sigma. The Subscription Receipts will

automatically be exchanged, without payment of any additional consideration or further action on the part

of the holders, into common shares of Sigma immediately prior to closing of the Proposed Transaction.

The net proceeds of the Private Placement will be used for ongoing exploration and development of the

Project, as described in more detail above, and for working capital and general corporate purposes. Funds

from the Private Placement will be held in esc row and will be released to Sigma if the conditions

precedent to completion of the Proposed Transaction have been satisfied. If such conditions are not

satisfied within 60 days following the closing of the Private Placement, funds will be returned to the

- 4 -

subscribers without deduction. The Subscription Receipts were offered in Canada, the United States and

in jurisdictions outside of Canada and the U.S., in each case in accordance with all applicable laws. The

Agents will be entitled to agency fees of 6% of the gross proceeds of the Private Placement and warrants

to acquire (at an exercise price of $2.00 per share) such number of Sigma common shares as is equal to

3% of the number of Subscription Receipts issued.

Margaux Red Capital Inc.

Margaux is a capital pool company incorporated under the provisions of the Canada Business

Corporations Act with its registered and head office in Vancouver, British Columbia. Margaux is a

“reporting issuer” in the provinces of British Columbia and Alberta. Margaux does not hold any interest

in any of the consolidated assets of Sigma.

The Proposed Transaction is an arm's length transaction subject to requisite regulatory approval,

including the approval of the TSXV. A filing statement outlining the terms of the Proposed Transaction is

currently being reviewed by the TSXV, and will be filed following completion of that review and

settlement of any comments of the TSXV.

Margaux currently has 6,696,750 Margaux common shares issued and outstanding. Under the terms of the

share exchange agreement for the Proposed Transaction, an aggregate of 662,978,250 Margaux common

shares are to be issued in exchange for all outstanding Sigma common shares, being an exchange ratio of

10.045125 Margaux common shares per Sigma common share. Since (as noted above) the Proposed

Transaction is not a non-arm’s length transaction for purpose of applicable TSXV rules, Margaux

shareholder approval is not required for the Proposed Transaction. Following completion of the Proposed

Transaction it is expected that shareholder approval will be sought to change Margaux’s name to “Sigma

Lithium Resources Inc.” and to do a consolidation of the then outstanding Margaux common shares.

The respective pro forma holdings of Margaux upon completion of the Proposed Transaction is expected

to be as follows: (i) Margaux’s current shareholders will hold 6,696,750 Margaux shares (1%); (ii)

506,274,300 Margaux shares (75.6%); (iii) 56,252,700 Margaux shares (8.4%) will be held by holders of

Subscription Receipt investors.

Board of Directors and Management

In addition to the directors and officers disclosed in Margaux’s December 22, 2017 press release, it is

expected that additional directors of Margaux will be appointed upon completion of the Proposed

Transaction, the biographies of whom will be included in a press release at the time.

Trading Halt

Trading in the Margaux common shares has been halted and may remain halted pending completion of

the review of the Proposed Transaction by the TSXV. There can be no assurance that trading in the

Margaux shares will resume prior to the completion of the Proposed Transaction.

Sponsorship

A waiver of the sponsorship requirement has been conditionally provided by the TSXV in light of the

Private Placement being brokered.
