Where pioneering strategy
meets hard-asset heritage

In 2008, Eduardo Tavarez and William Rosa forged a partnership with a singular purpose: to design investment strategies that create lasting, compounding value. Over the following years, they developed an innovative methodology for identifying high-potential ventures — channeling capital into startups and expanding operating businesses across industries. It was their deep, historical connection and shared expertise in gemstones that ultimately gave rise to Worcon Mining: a company built at the precise intersection of hard assets and institutional finance.

Today, under the leadership of Eduardo Tavarez and William Rosa — the family's gemstone assets have been consolidated, professionally appraised, and structured for international capital markets. Mining concessions span over 2,100 acres across Brazil's historic gemstone heartland.

Building on that momentum, Worcon Mining pioneered the use of gemstones as collateral for mergers and acquisitions — unlocking entirely new financing pathways. In 2020, operations were formally reorganized under World Connection Group Co. LLC — a U.S.-based holding company — with partnerships spanning the USP Mining Laboratory, independent gemologists, and high-yield international trading platforms.

Partnerships & Policy

relationships

Worcon Mining's delivery model is built around long-term institutional alliances that give our clients and counterparties unusual leverage — from U.S. foreign-trade policy access through our partnership with USFTI, to logistics and precious-metals execution out of the Dubai hub through Jonro Global Trading. Each alliance is deliberately chosen to close a specific capability gap across the Americas, the Gulf, and beyond.
