Ladies and Gentlemen:

We have acted as counsel to
Jones Ventures INTL Acquisition1 Corp, a Cayman Islands exempted company (the “Company”), in connection with
the preparation of the Registration Statement on Form S-1 (the “Registration Statement”) filed with the U.S.
Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities
Act”), relating to the offer and sale by the Company of up to 23,000,000 units of the Company (the “Units”)
(including up to 3,000,000 Units subject to the Underwriter’s (defined below) over-allotment option), with each Unit consisting
of (i) one Class A Ordinary Share of the Company, par value $0.0001 per share (the “Class A Ordinary Shares”),
for an aggregate of up to 23,000,000 Class Ordinary Shares (including up to 3,000,000 Class A Ordinary Shares subject to the Underwriter’s
over-allotment option), and (ii) one Right (a “Right”) of the Company, with each Right entitling the holder
thereof to purchase one tenth (1/10) of a Class A Ordinary Share, for an aggregate of up to 23,000,000 Rights (including up to 3,000,000
Rights included in the Units subject to the Underwriter’s over-allotment option) to be issued under a rights agreement (the “Rights
Agreement”) to be entered into by the Company and VStock Transfer, LLC, as Rights Agent, pursuant to the terms of an underwriting
agreement (the “Underwriting Agreement”) to be executed by the Company and Jones Trading Institutional Services
LLC (the “Underwriter”).

This opinion is being furnished
in accordance with the requirements of Item 601(b)(5) of Regulation S-K promulgated under the Securities Act.

In rendering the opinions
set forth below, we examined and relied upon such certificates, corporate records, agreements, instruments and other documents, and examined

we have examined and are familiar with originals or copies, certified or otherwise identified to our satisfaction, of (i) the Registration

the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us
as certified or photostatic copies, the authenticity of the originals of such latter documents, that all parties to such documents had
the power, corporate or other, to enter into and perform all obligations thereunder and all such documents have been duly authorized by
all requisite action, corporate or other, and duly executed and delivered by all parties thereto. As to any facts material to the opinions
expressed herein that we did not independently establish or verify, we have relied upon oral or written statements and representations
